Variable Tuning Technology.

“Now you decide how deep to play.”

The large flared ports can be re-tuned with the flip of a switch and the

removal of a port plug. In Maximum Output mode, the subwoofer transforms into a different device capable

of playing louder material with less distortion at the expense of some deeper bass.

Custom built woofers.

“The end of featureless boom.”

We design our woofers for sound quality, so you will hear clean and detailed

bass not found in lesser subwoofers.

Powerful BASH amplifiers.

Our custom built amplifiers work in concert with the woofer, protecting the subwoofer from damage and

keeping distortion to a minimum.

Flexible room placement.

The unobtrusive finish, rounded corners, and overall design allows for close placement next to listeners or 

discreet placement in corners.

Connects to almost any system.

“Integration is easier than ever.”

Thanks to modern receivers that use Dolby Digital, DTS, THX, or Bass 

Management, you can connect the subwoofer to your system with one cable. If you have invested in a

stereo-only system, integration is also simple thanks to true 24 dB/Oct. crossovers.
