General Features
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 won’t stop moving once it’s in motion. This extra movement (sound) creates a type of distortion that’s 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.
