Class D Amplifier
For subwoofer applications, Class D amps are beautifully efficient and their small size offers installation flexibility.

Dual Sigma Drive
This advanced negative feed back circuit improves damping factor and increases accuracy and sound quality. When a signal is passed to a subwoofer, like a 50Hz note, the speaker will move and create the note. However, because the speaker has mass and a suspension, it wont stop moving once its in motion. This extra movement (sound) creates a type of distortion thats not part of the original signal. The negative feedback circuit senses this unwanted movement and send out an opposite pulse to stop the speaker like an electronic brake.
