The 15" CompQ 2-Ohm
The CompQ 15" Subwoofer is the pinnacle of our round speaker line, with nearly identical construction and performance as our L7 square subs.
Built for high power handling and extremely accurate bass reproduction, this KICKER sub features Ribbed Santoprene® surrounds and a BlueLace™ large-diameter progressive roll spider for extreme flexibility at any volume level.
The CompQ 15" works best with a sealed or ported enclosure with 1200 watts of recommended power. See below for more details.
