LV12M is a smaller footprint version of LV12F. This budget level sub delivers the same articulate and tuneful bass that our subs are known for and yet provides enough HT bass thanks to its ported design. The combination of servo and a ported enclosure is what makes this sub deliver on both quality and quantity in bass.

Home theatre on a budget

Looking for an affordable home theatre sub that is also tight and musical? LV12M uses a front vented alignment to gain low frequency impact and output that home theatre demands. While many of our competitors limit their best technology to their top level models, we wanted to make Direct Servo affordable, so we've held nothing back. As a result, you get the tight and music bass you wouldn't normally expect from a vented subwoofer.

Direct Servo Technology

You may have heard about other servo subwoofers which are generally well regarded for their accuracy. It is a well established technology, most often based around an accelerometer which measures cone movement. Our Direct Servo technology has significant advantages over other servo technologies. We use a sensing servo coil which acts like a microphone which compares the original signal to what the subwoofer is actually reproducing. The signal is then corrected instantly to compensate for any differences. Once you understand the concept, you may wonder like we do why anyone would make a subwoofer any other way.

Some of the benefits of Direct Servo include:

• Reduction of the effects of thermal compression are eliminated under normal operation
• Higher efficiency allowing output which would normally require a more powerful amplifier
• Deep bass extension can be achieved using a low mass driver with superior transient response
• Mechanical and thermal memory effects are reduced, further improving transient response
• Much greater damping control over the cone with effective driver Q value of 0.1 resulting in much tighter and accurate bass than non-servo drivers with typical Q value of 0.3-0.5
• Dramatic reduction of the re-radiation of bass from inside the box
