New range of subs
Our range of subs has expanded
and we now offer a range of subs for music,
home theatre and combined systems. L series
is our entry level product line and F/E
series is our premium product line.
Output comparison
Every one of our subwoofers
has bass extension lower than 20hz. Our
frequency response specification is based
on -3db point which is far more stringent
than +/-3db that other manufacturers have
used. +/-3db is more like our -6db specification
because the former is equivalent to 0db/-6db
specification. Lower bass extension is also
advantageous in multiple sub setup.
At 20 Hz, our subs vary
in their maximum output capability. The
output at 20 Hz is shown relative to F12.
When comparing ported models
vs sealed models, ported models will have
more full body bass and it can contribute
a bit higher output in subjective perception
of bass loudness that is not reflected in
db numbers. Also larger diameter drivers
such as those in F18 do have more output
below 20hz.
- F12: 0db (baseline)
- F8/FM8: -1.5db
- L12: -1db
- F12-300: -0.5db
- LV12M: +2db
- L22: + 4db
- LVX12: +4db
- FVX12: +4.5db
- E15HP: + 5db
- F15HP: +5.5db
- G22: 6db
- E22: 6db
- F18: +7.5db
- FVX15: +8db
- FV15HP: +11db
- G25HP: +12db
- FV18: +14db
- FV25HP: +17db
Home theatre subs
For systems where home
theatre is the main priority, we recommend
our vented subs. At 20 Hz, a vented sub
is comparable to the output of two similar
sealed subs. LV12F
is our lowest cost sub and is designed for
smaller rooms and modest budgets. Our larger
15" subs are suited to larger rooms
and have substantially more output. Don't
be fooled by typical comments about vented
subs lacking accuracy. These subs are tight
and musical.
Music only systems
For music-only systems we recommend our sealed subs. We have sealed subs in various sizes and finishes. Where high output at 20 Hz is not needed, our sealed subs will match the output of their vented equivalents. In addition, greater extension is possible. Combined with room gain, in-room extension to 14 Hz or even lower is possible.
Combined systems
For combined music and home theatre systems, many of our 15" sealed subs are a good all round compromise. Our dual sealed 15" F25 is a very good choice, offering the LFE output of our vented subs but with the added bonus of greater midbass efficiency and output.
Direct Servo technology
The secret to accurate bass is in our patented Direct Servo technology.
A sensing coil provides immediate feedback
to ensure the cone precisely follows the
input signal. The result is very tight,
accurate and dynamic bass. Unlike many other
non-servo subs which exhibit two-mode bass:
either with too much bass when volume is
up or with too little or no bass when the
volume is down, our higher resolution subwoofers
allow customers to listen at lower level
and yet able to hear detailed bass in a
wide range of volume level.

Our customers say ...
From our customers we often hear comments like these:
"This is the cleanest, tightest, and most accurate bass I've ever experienced." ... Rob More
"... I am hearing notes I've never heard before." ... Kent B  More
" It's quite satisfying when you hear that some bass notes, previously thought to be a single note, are actually two notes or a series of shorter notes." ... Darren K More |
