CompQ Subwoofers

Experience every nuance of your bass. Thanks to outstanding power handling, next-level structural stability and a unique power plant, the CompQ™ discovers every note with miraculous detail. All with the highest RMS power rating we’ve ever achieved in a round subwoofer.

CompQ Sub Series Main


KICKER’s unique cone bracing technology ensures perfectly linear cone movement while the Blue Lace™ spider adds even more stability to the sub. You get unrivaled sonic accuracy and extraordinary volume.

CompQ Sub Series Stabilize

Take the Power

A ceramic magnet and computer-optimized voice coil provide outstanding power handling, while the UniPlate™ pole piece & backplate ensure the CompQ stays cool, even under extreme power loads.

CompQ Sub Series Take the Power

Join Forces

Spring-loaded copper terminals hold as much as an 8-gauge speaker wire, while extra thick tinsel leads bring all that music directly to the voice coil. You get every watt of power right where you want it.

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 cast aluminum frame provides an extremely stable, vibration-free base, so every note gets from the cone to your ears as pure as the day it was recorded. The CompQ 12-Inch Subwoofer works best with a sealed or ported enclosure with 850 watts of recommended power. See below for more details.
