The 12″ CompQ 4 Ohm

The CompQ 12-Inch Subwoofer is the best sound quality round driver we’ve ever made, with nearly identical construction and performance as our L7 square subs.

A thick ceramic magnet and heavy duty voice coil work with an extended pole piece to provide extremely deep bass reproduction – all without distortion. You get a strong, crisp sound that works perfectly with every kind of music.

The CompQ 12-Inch Subwoofer works best with a sealed or ported enclosure with 850 watts of recommended power. See below for more details.
