Reviews, Testimonials & Customer Gallery

Anxious about buying subwoofers online?

Perhaps you have been disappointed with products that others have raved about. We understand. We know what it is like because we have had the same experience. In developing our products we have tried many drivers on the market. Some were very disappointing. Some performed so poorly that it was not possible to achieve adequate performance even after they have been improved with our servo technology. If you are a fussy audiophile and insist on accurate bass, rest assured that our products have been designed with your goals in mind.

We often hear comments like these:

"Speed, articulation and incredible accuracy of this product is second to none in its own price range, and maybe 3 times the price category."
Sahin Derya (Istanbul, Turkey)

"... the Rythmik just sounds cleaner."
Kevin S. (USA)

"... my BK XLS200's are left far behind in EVERY aspect."
Martin J.(Sweden)

"The bass is all I have ever wanted: it is clean, tight and controlled, goes deep with authority and fits perfectly to my main speakers." Jouni A. (Finland)

"I am amazed at the low bass in music that I had never heard before."
Adam S. (Newark CA )

"It is such an improvement over my Monitor Audio FB210 I can't even believe it, and that sub cost $1000 new!"
(Matt S)

"This sub is so very tight and firm. I would of never thought that I would be able to own a sub that hits hard and very clean."
Scott K (Chandler, AZ)

Rythmik Subwoofers Used in Mastering Studios

Reviewer: Sterling Sound
Product: F15 with A370XLR amp for mastering studio use

Brian:

Thanks for this, the subs are working well in the studio(s), much tighter than the Velodyne's (ULD15 II) they replaced; which were admittedly 20 years old....

Here is a couple of pics of the subs in use at Sterling...

Thanks,

Barry

From Rythmik: Sterling Sound has purchased 3 pairs of F15 subwoofers for their mastering studios in 2008 and 2009. A great testimonial of the sound quality from our subwoofers.

Product: LV12R

I have had my LV12R Subwoofer for a little over a week now. I spent alot of time deciding between subwoofers. My choices were always from Hsu, Outlaw and Rythmik. One of these Makes, I was going to buy. After so many months of reading the same type of reviews of people saying flip a coin, they are all good. I decided to go with the rythmik LV12R, it being discounted when i bought it definitely helped persuade me as the HSU I was leaning towards was 699, well 639 for their summer sale. I have to say I am extremely happy with my purchase. Coming from an ancient Cerwin Vega HT-10PWR sub, it really only kind of filled the gap, and would bottom out alot. The LV12R obviously blows my old sub out of the water. I threw on some music from youtube that people had labeled bass test or sub breaker and laughed with gittiness from how the sub performed. You know, one of those laughs that are like, is this really happening, wow, almost sinister in a way. I have watched a couple of movies and played some games as movies and games are my main use for this sub. Max Payne, well i didnt realize how much bass/LFE was in this movie. Windows shaking, loose items rattling. Same gitty laughter from the amazement i felt with the youtube clips. Like being a kid in a candy store. No doubt i have to go around now and make sure anything that rattles is made rattleproof. Obviously if you look at the specs, you will see this is a large Sub. Let me tell you, it is large. Could be an end table for a couch. I dont mind the size now, but future apartments or living areas i will need to take into consideration my Sub and where it could go. As this will be something i will not ever want to part with short of winning the lottery, than i'll get one of my own personal IMAX theatres imax is selling now.

Product: LV12R

Hi Brian!

It finally arrived! Box was a bit damaged, it had a hole on the woofer side, but subwoofer was intact.

I'll be playing with my new toy and so far I'm impressed how clean the thing is compared to my BIC F12.

Great Job and keep the good work!

Just got my LV12R and I love it. So much cleaner sounding than the PB1000, that is pretty much it. I would recommend this to anyone that cares about the fidelity of their bass.

Product: FV15HP

Brought my FV15HP home today, holy wow this thing is amazing. I needed a sub that could keep up with my line arrays and this sub definitely does. Before this I had six Acoustic Elegance OB15's in open baffle with ~2200 watts and the Rythmik actually sounds very good in comparison; I get to enjoy transparent bass usually associated with open baffle subs but I also get to pressurize the room and save space doing it. It's a win-win :-). My Denon's XT32 processing dialed back the sub's volume more than I would have expected but that was an easy fix. I am now a servo believer :-)

Product: F12G-PEQ

Brian,

Just wanted to let you know how very much I am enjoying my F12G, which I am using in a stereo music system.

It replaces a sealed 10" Martin Logan Dynamo, and there is just no comparison. The ML got great reviews, but it can't touch the F12G -- of course not in terms of extension (~25 Hz v 14), but also in terms of absolute sonic accuracy.

My system is very nice, but I never heard truly natural, integrated bass below 30 Hz or so until I got the F12G.

And the PEQ has ably filled in a deep null centered at just below 40 Hz, making it unnecessary to buy a separate equalizer to do the job.

Thanks for a wonderful product.

Tom

Product: E15HP

I've had my E15HP for the last 2 weeks.

The original (much smaller) room had a water leak and was unavailable. Of course I decided to hook it up to my 2 channel setup (Linkwitz Orion 3.5 with subjective neutrality mod, Exasound E20 DAC direct to amp). I had high expectations of the E15 in this configuration given the Orion rolloff at 30hz and my expectations were met. The E15 is indeed very musical. I wouldn't say quite as musical as the Orion dipoles, with the room excitation issues of monopoles, but the extension and output blows the Orions away. I like to listen at close to realistic levels, and the dipole bass, while articulate, doesn't have the physics for a lot of low frequency dynamics. The E15 not only blends perfectly, but also adds a new sense of realism. Its the perfect compliment to an otherwise almost perfect setup.

As a side note, It also scares me a little and I haven't been able to turn it up anywhere close to what I used to do!

I played a few movies in this configuration with the Orions as L/R and completely ruined any expectations for my smaller HT sound. I wish I had this space (and budget) for the smaller HT setup. If anything this setup is too dynamic, which is a good problem to have I suppose.

So yeah I am impressed with Rythmik. Unfortunately this means I'll probably have to order another E15HP for my 2 channel setup. The other downside is having the Denon X.4000 in the chain. While its a good receiver and Audyessy XT32 is great and all, I prefer my DAC direct to amp without anything in between. Having the receiver in the chain, adds another veil.

The wife will be thrilled at the idea of buying another subwoofer, this time for the living room....

Cheers,
Greg

Product: F25

Well, here's my deal...

I am trying desperately to build a theater in the basement of my home. I now have everything other than the screen. Unfortunately, I have had no time for building, so the project is falling behind. As far as being properly calibrated, I have never used REW or any other program, but I am quite adept at using the BFD.

What I can tell you right now is that I was very pleased with my SVS 16-46PCi. A single F25 absolutely blows the SVS away! The difference is incredible.

The SVS plays deep and relatively clean compared to older subs I had. The Rythmik takes everything to a completely different level. I hear tiny nuances in deep bass that I had never heard before. Others use descriptions such as "cleaner" and "more articulate". These are good descriptions, but for me, it does not do justice to the difference in sound. The F25 (single as I have not hooked up the second) is different. The bass is there, it is not weak. It is also not boomy or muddy. This goes well with other descriptions. However, the best way I can describe it is...it is as if a veil has been lifted allowing the sound to be more natural and realistic. "Fast" and "Tight" are also words used to describe the sub. Again, good descriptions, but these do not go far enough.

OK, just a quick idea of what I am trying to convey...I am a fan of Johnny Johnson. Johnny was a tremendous piano player who was probably best known as being Chuck Berry's piano guy. Very late in his life, Johnny created some masterful CDs with other musicians. On one such CD, there is a bluesy track with really exceptional bass. I have always loved this track, but now, it sounds different. The pluck of each bass string can be clearly heard. Not just the pluck of each different note, but the fingers on the strings, the accompanying tones that the sliding skin on the steel strings creates...in perfect time. Don't get me wrong, the old SVS allowed me to notice a bit of this definition, but with the F25 it isn't just noticed when trying to hear it, it presents itself front and center in a way that makes me wonder how I went all these years without hearing this reproduced on my equipment. I am VERY familiar with this music and it sounds completely different and much better to me now!

I don't know if this is the holy grail of subwoofers for me. I do know that it is a real eye opener. I was very happy with my decade old SVS and I am in total awe of the F25's ability to wring so much more music out of the same recordings and equipment that I have owned for quite some time.

I will give you more of a description after the new year when hopefully I will be set up in the basement!

Product: E15

I have been enjoying the E15 for nearly 1 year--mostly for home theater use. Thank you for making such a wonderful product. I do not generally enjoy the bass sound that most home theater (and most movie theater) systems produce--rather than hearing deep bass reproduction, I am hearing the distinctive sound of a subwoofer making raspy, bloated, overdriven, distorted, honky, bass-ish sounds which I refer to as "subwoofer sounds". I am not an audiophile, nor a subwoofer expert, but to my ears, the E15 does not exhibit the typical noticable "subwoofer sounds". With system properly set up, it is somewhat difficult for me to even detect that "a subwoofer" is there, rather I hear endless bass extention and authority seamlessly added to the sound of my speakers--which is exactly what I was looking for. My wife and I have been thrilled with our purchase. I would highly recommend your subwoofers to anyone looking to elevate the sound quality of their home theater system.

Thanks,
Thomas Y.

PS. I would also like to add a note on the cost/value equation: For me, this was a lot of money to spend on a subwoofer. However, in my experience, it is hard for most normal people to hear much improvement between a typical $200 audio receiver vs. a higher-end $1000 receiver, or a typical ~$200 speaker vs. a higher end ~$1000 speaker--particularly while watching a movie. However, the difference between a typical ~$200 home theater subwoofer vs an audiophile-quality ~$1000 Rythmik sub is immediately and obviously audible to anyone. The difference is not only noticable, but also significantly adds to the overall enjoyment and experience of the sound. In my view, this represents an excellent price/performance ratio and a tremendous value. If I were putting together a ~$2000 to $2500 HT surround sound system (from scratch) all over again, the E15 would be my first purchase--no question!

Product: FV15HP-SE

After living with my new FV15HP for 3 weeks, I cannot wipe the ear to ear grin off my face every time I listen to it at volume. Or should I say, FEEL it at volume?

Going from two DefTech 12" subs in my 4000 sqft room to the FV15HP was incredible. Not only was the bass deeper, more articulate, faster, etc...it creates earth shaking experiences. When my buddy and I first unboxed it and ran a quick Audyssey calibration and played the IMAX Hubble launch we both thought plaster from the walls and fixtures on the ceiling were going to come down on us! Although neither of us have been to a shuttle launch it felt real with the FV15HP, even only at -13db.

I've always liked Tron Legacy, thought the bass sounded very good even with my DefTechs, but the 15HP brought it to the realm of FUN! It also made Cloverfield scary, WotW disturbing, Monster's Inc surprising, and the Transformers trilogy impressive. It made old music sound new, and new music sound incredible. I dug up an old Telarc classic, Timewarp and discovered new life in its lower octaves.

PacRim has its problems, no ULF and mostly one note bass, but the 15HP brings out sofa thumping mid-bass punch. I love it! Exactly what I was looking for in a sub $1500 sub!

I've been kicking around replacing this or replacing that in my HT, but this has to be my best upgrade besides going FP.

I auditioned other subs from ML, REL and HSU and none of them gave me the chest thumps I was looking for. Granted other ID brands might, SVS was highly recommended, but Rythmik just has the right mix of ingredients to make what I am looking for. Great customer service, great prices, great specs, great reviews, and a great community. Confidence to buy sight unseen/bass unheard.

My fav config is 1 port, 14hz, high damping. Only problem is the occasional port noise. Unfortunately it takes you out of the moment when it happens. Every time it happens I think about going dual port, but ultimately I prefer the punch of One.

Nonetheless, I LOVE THIS SUB!

Thanks Rythmik, Brian and Enrico!

From Rythmik: One port with 14hz and high damping provides a frequency response and sound closest to our sealed version. However, the downside is the roll-off is slower and when playing loud HT with that setting, it can cause occasional port noise. Our recommendation for HT playback with 1 port is 14hz and LOW damping.

Product: LV12R

So I finally Got my speakers and sub hooked up and calibrated. I have a LV12R and I just HAD to come here and rave about it. This thing HITS! I put in Fellowship of the Ring with the Balrog roar and steps that follow and good lord my clothes were literally flapping on my body. My wife and I have seen the movie dozens of times and she said this was the first time she actually felt intimidated by that scene.

I used this scene as a demo for her sister and husband. I had it paused right before the Balrog comes out of the fire and roars. I sat them down and made sure they were comfortable then turned off the lights and hit play and she jumped almost out of her chair. It was great.

VERY happy with the sub. Probably my favorite purchase I made for my HT.

Product: F15 (370WRMS amp)

Before I ask my questions, I need to mention that I have owned my F15 subwoofer for just under one year now (order #3725597) and it has changed my appreciation for music in two ways: first, it has seriously affected my taste in music. I used to spend most of my time listening to modern electronic music, but since adding the F15 to my system, I now enjoy a much wider spectrum of music. Two of my favorites are Donald Fagen and Dire Straits. Second, I was originally under the belief that I would probably need two subwoofers to keep up with my front monitors at a reasonable level of accuracy. I quickly realized that my thinking was backwards -- I actually needed to upgrade my front monitors to keep up with the Rythmik ...

I'm in love with the F15, and I promise that once I move into a larger house, you'll have a returning customer ready to outfit a brand new soundroom with a pair of Rythmik subwoofers. Thank you for the wonderful product!

Product: F15BM (370WRMS XLR amp)

I have had the F15 installed in my system since May.
1. Fit , finish, packing etc. are first rate. I hesitated to buy the cheaper plain black finish, but it is so nicely done that I prefer it to the shiny piano black which I have had with other speakers.
2. I am using it in stereo with Soundlab electroststics. Any dynamic sub is difficult to integrate with a diapole. I have tried several. The F15 is the best I have heard. Granted I have been fiddling with the controls for three months, but at least the controls really work.
3. My only suggestion is to replace the volume pot or add a swithch to give it more adjustment room at the bottom end. My speakers are so inefficient, that the volume control is nearly impossibe to adjust in small increments. I suspect that the tracking also suffers.
4. Despite #3, I am very pleased with the F15 overall, and amazed at the comparative value.

Product: FV15 (370WRMS amps)

I am a financial analyst, guitarist and bassist. My Home Theater Room is also my "jam" room. I am old school, all of my guitar and bass amps are tube amps ...I love analog sound. The main requirements in a subwoofer for me are smooth, juicy, dynamic sound ...and the ability to accurately "track" the bass drum and bass guitar. When I'm playing guitar or bass in my Home Theater Room I "have to" be able to adequately hear the bass drum and bass guitar or all is lost. The Rythmik FV15 has literally blown my mind, and my friends as well. I have 2 x FV15's that replaced 1 x paradigm pw2200. The difference is laughable. My 2 Rythmik subs even drown out my 2 x 15 Ampeg cabs powered by a 500w Ampeg Bass Head. The Rythmik's ability to "boom" for movies WITH the ability to accurately track any bass drum or bass guitar WITH dynamic musicality is amazing. The ability to run them with both ports open for sheer volume or plug one port for more depth is not a gimmick, it works amazingly well. The 3 position hi/mid/low damping switch is effective, but subtle (good thing). I have thrown everything at the subs, and they refuse to complain, they just keep thumping out solid, deep ...musical bass!!! 1 Million % Satisfied.

Initial Impressions on a pair of F15HP subs

Current Set-up:

Linkwitz Orion (rev 3.4) loudspeakers
2 - Genesis Technologies (old company) 700 surround speakers
1 - Genesis (new company) Reference Center channel speaker
2 - Linn Aktiv surround back speakers
2 - F15HP subs (replaced 1 Elemental Design A5-350 sub with 15" driver/550 watt amp)
Oppo 95
2 - Parasound A52 (5 channel amplifiers)
1 - Anthem MCA5 (5 channel amplifier, new caps installed in 2013)
Marantz AV8801 (ssp)
XBOX 360
Infinity HD DVR

My emphasis is 75% music and 25% HT. For the last several years, I have been using a ED A5-350. It has been okay with HT, but meh on 2 channel music. The AV8801 easily allows the sub to be used for 2 channel music listening. With the ED sub, I never listened to 2 channel music with the sub in use. With the Rythmik F15HP subs, well I am getting ahead of myself...

CHOICES, CHOICES

In the past couple of months, after speaking with Brian on several occasions about Rythmik subs, 2 channel music, home theater, my HT/music set-up, servo controlled subs and musical priorities, I narrowed down my Rythmik sub choice to either an F25 or a pair of F15HP subs. I shared pictures and dimensions of the two Rythmik sub options with my wife . She very much preferred the option of the two more diminutive F15 HP subs over a single F25 even though the cost was higher. A week ago last Monday, I called Brian and ordered a pair of F15HP subs with black oak grain and the XLR3 upgrade. As I live in NW Houston, I was able to drive to Austin and pick them up on Friday of the same week. Before returning home, Brian took some time with me discussing room placement options and to make sure I understood the function of the XLR3 amps. Though heavy and packed in rather large boxes, we were able to fit the pair of subs into the back of my Nissan Armada. Upon arriving home, I discovered that the subs were very securley braced/packed and doubled boxed. I would not be worried about having these subs shipped via UPS or Fedex. Brian also has a very cool way of easily removing the subs from the box (illustrated in a pictogram on the flap of the inner box) that consists of removing all the padded inserts but one, placing the box on its side and sliding the sub out on the remaining padded insert. I was not expecting a great deal in the looks department from the F15HP subs, so I was pleasantly surprised as to the subs' handsome appearance. The fit and finish was also top drawer.

SETUP AND LISTENING

I positioned the subs along the front wall, flanking my Linkwiz Orions. I used a pair of xlr cables to connect the subs to the Marantz AV8801. I ran the Audessey XT32 program and I was up and running in no time. The Audessey XT32 always sets my Orions as large speakers. For the next 3 hours I listened to 2 channel audio - classical, jazz, folk, pop, blues. During this time, I switched the front configuration back and forth from large to small taking the F15HP subs in and out. The Linkwitz Orions with the very robust 10" SEAS bass drivers (2 drivers per channel) are very convincing in the lower frequencies. As I mentioned before, with the ED sub all my 2 channel music listening was done only with the Linkwitz Orion. After installing the F15HP subs, I can definitively state that I preferred 2 channel audio with the F15HP subs turned on. This was true whether Audessey 32 was on or off. The Linkwitz Orions (set large) sounded excellent without the F15HP subs. With the Linkwitz Orions (set small) and with the F15HPs on, the music sounded even better. On multichannel music (SACD and DVD-A), my system has never sounded better. I have watched a couple of movies with the F15HP subs in the system, and I can also state that HT has never sounded better.

I am extremely satisified with the performance of the F15HP subs.

Reviewer: Sumpwitch (AVS member)
Product: LV12R

So here is my highly anticipated by no one, yet long winded review of the LV12R¡­

First, I should preface this review by saying that I am a noob. My only experience with HT prior to my new setup was with a Bose Lifestyles system. (Now take it easy ¨C this was purchased by the wife pre-Sumpwitch, so put the torches and pitchforks away). However, I am an avid fan of live music and have played bass for 20 years, so I¡¯d like to think I know what decent bass sounds like ¨C just not necessarily below 30hz.

My room is a very modest 1500 cu. ft., so I knew that this sub wouldn¡¯t have any issues with room size. I will be using this for at least 50% music though so I was a bit worried that this sub would be way too much for my Infinity Primus setup and end up boomy or obnoxious - especially since it has the capacity to go below 20hz. I¡¯m a sucker for a sale though ¨C hence the 65 inch tv that left me with a smaller budget for speakers ¨C and it seemed like Brian extended the price just for me. So after a few days of wife convincing ¨C I pulled the trigger on the LV12R.

I ordered late on a Thursday night ¨C so basically Friday ¨C and it showed up the next Wednesday. Unboxing and setup was a breeze. I appreciate that it was packed in an extra thick box with sturdy foam inside, yet I didn¡¯t need a contractor, team of horses or a plasma cutter to get into it. The sub is shipped upside-down so you can screw the feet on and just flip the box over which is a nice touch. I set it up as recommended by the settings sheet included in the box and was ready to go.

The timing of its arrival ended up perfect for me because the Wed. thru Fri. evenings were spent doing some final touches in my room, so the sub was able to get 20-25 hours on it (mainly music at moderate to slightly above average levels) before I was really able to focus on what it could do. I ran Audyssey on Saturday morning and was ready to go.

THE FIRST MOVIE
So apparently my wife was on another planet (probably visiting her mother) at the beginning of this century and never saw any of the Lord of the Rings movies. What a perfect way to initiate the new room. I fired up the extended Blu-Ray box set and cleared our schedule for the rest of the day so we could dork out.

The accuracy of some of those sounds was amazing. For instance, in ROTK when the trebuchets are launching giant chunks of stone ¨C they land with a nice deep THUD. And that¡¯s it. No lingering overtones or rumble. It¡¯s exactly what I think that would sound like if I were on that field which is a testament to the quality of that soundtrack and the ability of the LV12R to reproduce it. I won¡¯t go into a scene by scene review, I¡¯ll just say that the LV12R exceeded expectation. I could even feel the bass through my giant hobbit slippers (told you I was going to dork out).

The most impressive thing to me is that the sub blew Mrs. Sumpwitch¡¯s mind. Her exact words after the Balrog scene were ¡°WOW! That was pretty f#$%ing cool¡±. Now, this might not sound like a big deal, but this is NOT her thing at all. Here¡¯s an example: One of my other hobbies is racing a blown-alcohol drag boat with some friends. I invited her out to one of our races because the top fuel boats were in town. Now I¡¯m not sure if you guys have ever seen a top fuel car or boat in person before, but those things are ROWDY. 16,000 HP going off at once has crazy low frequency at insane dB. Pretty cool to see even if racing isn¡¯t your thing. So after the first round of top fuelers go off, I looked at her to get some sort of approving nod or gesture to legitimize my hobby¡­she was shoulder-shruggingly unimpressed. Cue the sad trombone. So for her to dig a sub like this is akin to Paula Deen saying ¡°Wow, that low-fat salad was pretty f#$%ing delicious¡±.

SOME TUNES
This is the area I was a bit concerned about. Most of the bands I enjoy either provide an HD stream or allow fans to stream or record their concerts ¨C so I listen to lots of music and was concerned that the sub wouldn¡¯t perform as well here. Some of my worries were put at ease by the accuracy of the movie soundtracks, but I am real picky in this department.

I was having some AVR connectivity issues at first so I had to start with a few DVDs. I started with a few tracks off the Black Crowes ¨C Cabin Fever, followed by the Allman Brothers Live at the Beacon Theater. My initial impressions were just OK. The Black Crowes cover of the Velvet Underground song ¡°Oh, Sweet Nuthin¡¯¡± has a nice melodic bassline that the LV12R handled fine. The Allman Brothers version of ¡°Rockin¡¯ Horse¡± was a bit more impressive. Oteil Burbridge has some nice low pedaling in this song that the sub played tight and accurate. Hindsight being 20/20 allows me to realize that the mix on these DVDs is not very bass heavy so it is hard to make a fair judgement based on them.

The next DVD I tried was Phish ¨C IT (disc 2 ¨C it has no interviews interrupting the music). I could tell from the tune playing at the start menu that this was going to be much different, the bass mix is a lot heavier on this DVD than it was on the last two. Mike Gordon plays with a pick on a Modulus bass that has a graphite neck, so the attack has a very distinct tone. On the intro of the second track (Limb by Limb), when the kick drum and bass come in is a great example of how accurate the LV12R is. It is a simple moment musically, but the kick drum punches in and the simple thum-thum-thump of the root note at 44hz comes through tight and clear with every characteristic of that Modulus bass recreated perfectly. I really only meant to play a track or 2 off this DVD, but I didn¡¯t stop listening for 2.5 hours (and I have seen this DVD a number of times and was at this festival). All I can say is ¡°WOW¡±. I don¡¯t quite know how else to describe it other than it felt like my ears had just got laid. Maybe THAT should be the Rythmik slogan.

I have since fixed my connectivity issues and have thrown all kinds of stuff at this thing. Flea, Claypool, Steve Harris, Victor Wooten, Bootsy¡­the LV12R just shrugs them all off. Drums sound amazing through this. Put on Zeppelin¡¯s ¡°When the Levee Breaks¡± and you¡¯ll swear you are standing in that stairwell where Bonham recorded it.

I did not put any rap, dub-step, or bass competition tracks through it because, well frankly because I don¡¯t care if it can handle those or not. Just not my thing that¡¯s all.

CONCLUSION
I realize that my setup and room are very modest and that it wouldn't be hard to fill my space with good sounding bass. There might even be other subs in this price range that are comparable, but if there is a non-DIY sub out there that is better, goes lower, or is more accurate for what I paid ¨C I¡¯ll be a monkey¡¯s uncle.

I love the LV12R. I¡¯d let it date my sister if it wanted to. My only regret is that this sub may have opened a can of worms on another expensive hobby (like playing in bands and racing boats).

Product: LV12R

Okay so Iv put over 20 hours on my new rythmik lv12r and I'm ready to do a final review on it.

First of all my room is 12x13 and has pretty crappy room acoustics. My corners grab most of the bass so when I did my demoing I sat in a specific spot in the room where the bass is good but not crazy overpowering like it is in the corner

I ordered my sub on a Saturday and it arrived to my house on Wed so it was pretty quick.

When I received it the box was slightly beat up and a hole in the middle corner of the box but there was no damage to the sub. It was not double boxed but shipped with nice thick foam on the inside to keep the sub away from the box invade any punctures or damage was to happen.

Setup was realitivly easy just a power cord and an lfe. Although I really didn't know how to use the sub at first (there were options such as lpf slope and bass extension I was not used to. However simple reading of the directions made it easy to understand what theese options did and even recommended a setting for music and movies.

My intitial thoughts of the sub after running yapo were actually not the greatest. I had to turn the volume level on the sub to about 80 percent and +5 on my avr to get significant power gain results over my dinky pro.sub 600. I continued to play a little rap music to let it break in for a few hours and then re ran yapo.

The second time was a little better as I had the sub volume to 70 Percent yapo put my sub at about -1.5 on my Avr. I could feel the opening up more around the 40-90hz range (I'm guessing I don't have an spl meter yet but I will soon) at mid level listening. The sub seemed to be getting more punchy and slightly more noticeable or maybe better worded made a nicer presence. I listend to it like this playing different movies and music for about 10 hours. In this time I realized it also takes time not only for the sub to break in but my ears as well and just as importantly. Ill explain that next

The sub I was previously using is a little deftech pro sub 600. When I first got it I thought it was awesome! And still.do think its a nice little sub for its size. Anyway when I first got my rythmik I thought it was underpowered because I was used to the boomy sound of my pro sub. It took time for me to get used to how amazingly the lv12r blended with my speakers. It blends so well that its really was hard to tell it was even on at times of low and even medium lfe. That's exactly what I wasn't used to and its exactly why I thought the lv12r was underpowered. Its cause I was used to the boomy obnoxious pro sub. Also remebet that at the same listening.g levels the pro sub was at 90 percent cap where the lv12r is at 30.

After 20 hours and and running yapo for the final time the final results were 55 percent on the sub and 0 on my avr which I bump to +3 for movies. After whatching some blues rays that consisted of hulk,the avengers,looper, lord of the ring 1, and many others I have to say I am in love with sub. It has opened up sooo much and I now realize the deep quality tight bass of has. My ears are used to it now and I wonder how I ever called this sub underpowered.

On thing I love most is how just when u think this sub is close to being.g maxed out its not. It keep powering through even the hardest lowest hitting lfes without any sign of distortion or loss of control. Honestly I have never heard it distort yet even in my torture tests where I thought it would for sure.

Also this sub is the most accurate tightest sounding bass I have ever heard. Its very fast and I belive it can keep up with anything and probably put anything to shame in its price range.

Hats off to rythmik I don't thinks there is a better sub for 550 dollars out there period. I love it.

If I missed anything let me know guys! Its my first ever sub review so go easy on me hahaha:)

The F12 is up and running. Boy oh boy this thing is sweet. I realize that conventional wisdom is that in a 4,000 cubic ft room I needed a 15" and/or ported sub but I'm glad I stuck with the 12" sealed. I have it hooked up with both the LFE and line in from the preamp outs (and no, the earth's magnetic field did not reverse itself ). I ran Audssey with LPF on AVR/12, crossover at 50 Hz (my mains go down to 44 Hz), Delay/phase at 0, rumble filter off, & extension filter at 14 Hz mid damping. I'm using a Marantz SR 7005 AVR. Audssey set the sub at -0.5dB and about 2 feet farther away than my main speakers.

For music I listened to Beethoven's 5th, the Telarc Cincinnati Pops recording of Tchaikovsky's 1812 Overture (in both DTS 5.1 and 176/24 flac formats), and the Chesky test disc Vol 2. For movies I watched parts of Demolition Man and Serenity both in DTS-MA.

I listened to the sub with the damping set at both mid and low and volume ranging from the initial -0.5 dB to +2.5 dB (3 dB hot). I ended up settling on the initial settings of mid damping and -0.5dB.

Even with damping on mid and not running the volume hot this sub fills the room amazingly. With music the bass is full and sweet, not overpowering or localized. You cannot tell the bass is coming from the sub unless you walk over and stick your ear next to the driver. The bass strikes and cannon fire in the 1812 Overture are full without being overpowering or harsh. As for the movies, Serenity has never sounded so large or come to life so much. This 12" sealed sub can definitely shake the walls (I may have to switch to high damping once the wife gets back home ). Even though this sub is putting out way more punch than anything I have had in this system before the effect is desirable not harsh or nerve grating.

Up until a few weeks ago I had never heard of Rythmik. I'm sure glad I did and that you all have been as helpful, and tolerant, as you have. Brian, thanks for your help both on the forum and over the phone.

By the way, did I mention the F12 is on sale, $787? The F12 is so far beyond any other $800 sub I've been auditioning over the past two months it isn't even funny. It even blows away the $1,600 servo sub I was trying to justify buying.

Bottom line: even if your listening area is larger, don't discount the F12, I couldn't be happier. Now, back to the movie

Product: LV12R

I recently purchased an LV12R for my similarly sized basement room (3100 cubic feet, fully closed). I was upgrading from a Boston PV800, which from what I can tell is similar in output to the BIC PL-200. It's a 12" 300 watt ported sub, ironically the same as the LV12R. I examined the spreadsheets from Audioholics to compare what I had with what I wanted. The Boston has been a durable sub for 10 years (I always use my sound system for TV watching) but it was not really able to produce the output and extension I wanted in my new basement. My target was something on the spreadsheet that produced >100db at 20Hz whereas what I had could manage 85db at 20Hz.

The comptetitors I looked at in this price range included Outlaw, Epik and SVS (among others). What impressed me about Rythmik is that it uses a servo amplifier (a unique kind of servo at that), Brian posts all the time in this thread with advice and the reviews of the sound quality have all been glowing.

Now that I have the LV12R in my room I can see what everyone was raving about. Quality AND output. Wow it is really nice. I struggled for awhile trying to decide if I should get an F12 instead but from what I read even the ported Rythmiks are quality enough for music and when it came down to it I watch more movies than listen to music so I need the output. I actually had 2 subs running in my room before (the second was a Mirage LF100, 8" ported) to smooth the standing waves but this single Rythmik has much more output and extension than the other two combined.

I queued up one of my favorite bass scenes - SW Episode 2 when Amidala arrives on Corruscant. The LV12R was able to play the ship's engine noises/sonic boom and the explosion effortlessly where my previous subs would chuff and bottom. The explosion actually flapped my jeans and jiggled my couch! I can see the benefit in having a second sub to smooth out the standing waves but the output of this thing in my room was definitely satisfying and exactly what I was hoping for in an upgrade.

My only problem now is that I can appreciate having the extension switch in medium or high for music and low for movies so I am frequently getting up to flip that. If the LV12R didn't have the option I'd probably be blissfully ignorant but since I've heard the difference I find myself prefering different settings for different things. In the med or high extension setting it is completely satisfying for music. This is definitely not a one note subwoofer. Well done Rythmik!

Hi guys,

I just wanted to let you know that I've been trying out the F12 for a couple of weeks now and I'm loving it. I haven't gone through the entire setup procedure yet, but even just roughly positioned between my two ProAc monitors and calibrating the balance by ear, I am getting a wonderful, deep, and punchy low end that I have never heard before. Apparently this method of repositioning the source of the low end has solved many of my bass cancellation issues.

I have not yet received the 'in line' HPF filters I ordered from Harrison Labs, so for now I'm just using the HPF output of the F12 to feed my Rotel amp and ProAcs. Seems to work well, and have not noticed the 'veiled' sound that one audiophile reviewer was mentioning. But will compare to the Harrison filters soon.

Thanks again for all the advice. Once I get into doing the full setup procedure as specified on your website, I may need to consult with you again. But for now, very satisfied. Thanks for this great solution to the low frequency monitoring challenges I was having.

Best regards, Terrence

Brian,

Set-up the 2nd F12 and switched the amp on my current F12....stereo subs!!!

The quality of the bass with one sub is already great..... adding the 2nd has filled out the soundstage, and balanced out the room interaction....plus, I listen to a lot of live rock audience recordings and soundboards with two drummers...dual F12s has me in bass nirvana

I am now in the "done for now" situation.....Magenpan 1.7 and dual F12's is about as good as I have ever heard and best I have ever owned. The word of mouth about Rythmik + Magnepan, as winning combo, is the real deal. My sub search is over!

Thanks again for your patience with me, great communication, and awesome products

Product: FV15HP

I purchased an FV15HP about two years ago, which is usually the time period I start thinking about an upgrade. Not so with the Rythmik sub. It is a perfect blend of brute force for movies and detailed nuance for music. It still continues to thrill each time I use it. I've shifted more from movies to hi-def audio, and the sub continues to reveal information and complexity in tunes I've listened to hundreds of time, the latest being Led Zepplin's Moby Dick. I usually skip the drum solo but it sounded so amazing and life-like that I had to listen to it a couple of times. Keep up the great work.

Hi Brian,
Just received it today! Though only listen to a few albums & 1 movie so far, 3 words: Amazing amazing amazing! I know it'll get even better as it runs in but the F12 already smokes my 1 yr old SVS SB12NSD but I guess you already know that. It's really amazing how clean the low frequency can sound. From memories I think Rythmik better than MK or JL Fathom. You're a genius!

Robin

Hi Brian,
My jaw drop again! As I run-in the F12 more, about 20hrs now & just watched Star Trek V., the experience is phenomenal, the low frequency attacks are so real & dimensional because the booming or distortion are gone. The F12 ultra low noise floor is more apparent as it run-in more. The combination of F12 with my ProAc 110 (bookshelf spk) has remind me of my listening experience of the 6ft tall Wilson Watt I sh*t you not! Even the movie finishing classical music was a joy to to listen to the last drop. Impressive indeed!

I feel like I am cheating the musical gods. The F15 blends so naturally and precisely and stays out of they way when not needed in both audible and inaudible bands. I cross it over at 45hz and it insinuates itself into my Unifield 3s soundstage without stepping all over the Von Schweikerts. It's a huge upgrade for sure; Blows the REL away!

I have the sub connected speaker level and LFE simultaneously to accommodate 2 channel listening and HT in the same system which saves on having to buy separate subs for each.

The sub in that picture was a DIY ED sub that replaced an A2-300, I had 4 subs in my room when I took the first pic. That one ED DIY sub, one Klipsch RPW12 and the Def Tech towers with built in 10s. I since sold all of the subs and am down to the single FV15 and there is no comparison, hands down the FV15 smashes all of those subs!

It is sooo much cleaner sounding it took a while to get used to, but now I am hearing things in songs I never heard before. I just never had a sub this articulate to really show off some of the songs I thought I knew. These are songs I have heard 100s of times and they sound brand new all over again. Also for movies, this single sub can shake my house! My roommate is across the house and I shook all of their shampoo bottles off of their shelves in the bathroom across the house and my sub is on an isolator!

I am glad I went with the Rythmik, for music it is sooo crisp and clean and yet it still has that low earth shattering bass for movies. My old setup was not bad but I just never knew what I was missing till I got my FV15. I think I will get another here pretty soon to balance out the room aesthetically because this guy is a work of art to me.

Product: F15HP-SE/Sierra-1

Just wanted to drop you guys a line to let you know how happy I am with my F15HP-SE which I got a few days before Xmas (bought via Dave @ Ascend). It is everything I hoped it would be in my system; clean, transparent, and detailed, even at low listening levels. I thought I'd relay the story of what my wife said last night:

My wife Beth rarely sits with me when I'm listening to music, but she came downstairs late last night to get some water. I had my Diana Krall station on Pandora playing from the OPPO, and Beth came and sat down for a while. She listened to a few songs by Diana Krall, Tony Bennett, Ella Fitzgerald, and Michael Buble. I said "listen to this"; and muted the Rythmik with the SMS-1 remote for a few seconds, then un-muted it again. "Wow, it's like adding a whole other dimension to the music!" said my wife. "That subwoofer was a good buy. My favorite part about it is that you don't even know it's there, its just part of the music and you can't tell there is a subwoofer in the room."

High praise indeed from someone who isn't much interested in music or the audio hobby.

------------------

I wrote the above last month, but didn't get around to sending it. I bought a BAT (Balanced Audio Technology) VK-31SE preamp from Audiogon and to arrived yesterday. I listened to the BAT with my Sierra-1's and F15HP-SE/SMS-1 for the first time last night after the kids had gone to bed. Wow! Now I know what people mean when they talk about "texture" in the bass. And if I thought the Sierra's disappeared before, I was mistaken. They were hidden before, but they have vanished now, and there is nothing but music floating in space.

At this point I have to wonder how much better things can get; thanks to both of you for providing such fantastic products at reasonable prices!

I'm 40 years old now, and I'm disappointed that I have gone most of life until this point without experiencing really great music! At least my children will always know great sounding music, and not miss out like I did.

Thanks,

Mike S.

Product: F15HP

I have moved the settings around experimenting but do not really notice a huge difference but I haven't done detailed tests with specific material across the board for each setting - will do that over time. I still do not really understand how each control affects the output. I'm just not well enough read yet to grasp 1st, 2nd, 3rd, 4th order etc. It's a bit above my level but I am learning by reading.

The F-15 fills my area completely. I have done some serious listening with bass heavy tracks - Rush, David Gilmour, Chris Rea and can hear the note scales beautifully. I am a guitarist and a former drummer/percussionist so I can distinguish a note's tonal qualities and the F-15 really delivers. Neal Peart of Rush has an enormous array of drums and the detail that the F-15 reveals when he is thundering away is so precise. Granted, my main speakers are not what most would consider audiophile grade but they do a pretty good job and I am happy with them (for now- until funds are available to look at more upgrading). The power this thing puts out is staggering, the LFE from movies is visceral. I read on the forums of how people are running three or four15 inch subs in rooms smaller than mine and scratch my head... I really think that my single F-15 does everything needed for my big room but then again, I am somewhat new to this.

As you can see from my ownership of the old M&K sub (purchased 1991), I buy stuff and keep it forever - I do my research and am usually very happy with my decision. The F15-H600 was an excellent choice and will probably be the last sub I ever need. You have designed and developed an amazing product and I am totally happy with it. If at some point in time I ever get set up with REW or any other type of measuring device, I will let you know what the results are. I'm sorry I cannot give you any more than I have here but rest assured that I am a satisfied customer and recommend your products to anyone searching for a sub. Thank you.

This is an unbelievable sub. This sub is for audiophiles who think a subwoofer will ruin the sound of their set up.There are so many options to list so this sub will and can fit into any set up. And yes it will shake things up if you want its just that you can hear so much detail and it will not miss a beat on fast tracks yet manages to still hold onto those really low hz sub 20 and lower. So you just wont feel the need to have it loud because everything is all there depth , speed, thump, feel, musicality.

Hello Brian, I hope this finds you well.

My goodness. Having waited for so long for the subs, I can only say that they do not disappoint. It's been a wonderful day today. Having spent several days hammering away at the room, endless measuring, moving, trapping, tweaking; finally I can sit and listen. And things are good.

The subs are virtually invisible, simply providing solidity, depth and a wonderful sense of envelopment that I haven't experienced in such a natural way before. They don't boom, they don't fuzz, they don't do anything other than feel like thoroughly excellent speakers that play low. Very low. They feel like a natural accompaniment to my (Klein/Hummel) O300s. In fact they feel positively complimentary, not least in terms of how they helped to smooth the LF response in the room. Working on the setup today made it clear that - despite it being a pain in the *** for you - I made the right choice in going with Rythmik. I think I said to you that everything else seemed like a compromise. I am glad I didn't.

I'm not just happy, I'm absolutely thrilled with them.

Thanks ever so much for everything.

With best regards,

Brian, just a little follow-up on your low pass setting explanation-thanks loads!

I am running my D15se, in LFE+Mains setting on my Denon 985P. As I mentioned earlier, I am using AR9's full range-each has two 12" acoustic suspension woofers; upper crossover is at 200 hz,(internal tower crossover) and they are down 3db at 28hz. My D15 is located three feet in front of the AR's, and to the left a couple of feet, against the wall (the AR's are on either side of a Pioneer Elite 50"plasma, and against the rear wall)

I ran my Denon microphone equalization, and everything sounded pretty good, but the low end response sounded very thin--I didn't realize, at the time, that the phasing, between the AR, LF drivers, and the D15. had to be addressed. I switched from LFE, to AVR/12 and found and adjustment of 90 degrees, put both the D15, and the AR's spot on!!!! I can't believe the fantastic results!!!!!!!!

The main thing I think is missing in setup situations is that everything is addressed to 80hz crossover, with crossover phasing as the driving factor-if your fronts have extended LF response, you have to be doubly on guard to phase your LF drivers, or you have minimal, to little LF response.

Again, thank you for your personal touch, with your customers. You have a customer for life here.

Sincerely,

Sounded like depth charges going off in the room with my basement concrete floor shaking. I'm a believer in Rythmik subs.

Product: F12SE

I freelance in the film industry as a 2nd Assistant Director (AD) and, resultantly, possess a love of film that follows me home from work. In my media room I have a 5.1 channel setup with an M&K sealed box dual 8¡¨ subwoofer. Miller & Kreisel subs are (were) legendary for their authoritative bass and the speed of their drivers. In fact, my dual 8¡¨ has the Super Fast Bass Drivers and handily keeps pace with my main speakers.

What was lacking, however, was bass presence in the room. The space is 2400 cubic feet and although the sub imparts bass extension to films or music, it never loads the room with lower octave energy. On explosive soundtracks like the end of Titan AE in the ice crystal field, the M&K¡¦s drivers frequently attempt to release themselves from their enclosure. Oh, and the M&K's amplifier could keep your hors d'oeuvres warm with its heat generation. In short, the laws of physics are stacked against a smaller sub¡Xeven with dual, push-pull drivers.

I did extensive research and narrowed my search to Rythmik and one other company. What clinched the deal, though, was the Direct Servo technology incorporated into your subs. I purchased an F12SE while I was actually still on location shooting in Boston and only recently returned to Los Angeles to set it up and give it a listen. Here are my thoughts:

First and foremost, the energy the F12SE imparts into the room is palpable. That¡¦s not to say bloated or boomy; rather, it makes its presence known when called upon for duty. Anything that plumbs the lower octaves is given extra weight by the sub. I never experienced this with my M&K. And I mean never.

Back in 1999, the electronic band the Art of Noise released a CD entitled The Seduction of Claude Debussey, which was a soundtrack to the film about the French composer that was never made (their description, anyway). Regardless of what you think of electronic music, the production on this CD is exemplary. The first track has the rich voice of the actor John Hurt set against a cornucopia of bleeps and blips and bass drum hits. The third track has a series of amazing bass energy sweeps that actually fall below the range of the sub. In all instances, though, the F12SE absolutely mesmerized me with its ability to slam when needed while never losing composure. I cannot get enough of its musicality. But wait, there¡¦s more¡K

Because of my job, many of my friends are also Assistant Directors. We usually gather at my place (I have the best HT setup) and watch a DVD together, usually a film that one of us did. My friend suggested Transformers, as he had worked on it. Perfect choice. It would also give me a chance to run an uncompressed, high-resolution soundtrack through my system with the sub. ¡§Wow¡¨ doesn't even begin to describe the experience. If your product can silence a room of jaded industry folks, you've done your job. Every explosion, crash, robot footstep and anything else the sound mixers cooked up was rendered with precision and grace. Not once did it sound like a subwoofer. It just sounded like, well, giant robots were fighting in downtown LA for the future of mankind. We could discern, say, a giant footstep from the sound of a robot hitting a building. Every detail of the mix could be heard.

I can not sing the praises of the F12SE enough and none of us can wait for the next movie night.

Best,

Brian,

I received the subwoofer yesterday. The finish is really excellent. I read the info on your site about phase, but since I have no information about my main speakers I ended up just A/Bing different adjustments until I got it where I wanted it. Only took about 20 minutes. My main speakers are Dali Grands that are about 10 years old. The ¡V3db point is 33hz. I used the 40/24 setting and the subwoofer integrates extremely well. One would be hard pressed to realize there is a subwoofer in use, at lease until I put on the Massive Attack vinyl. :-)


I just wanted to say thanks, you have a terrific product and I am very pleased.
