Kicker's 43VCWR122 CompR 12" Subwoofer Enclosure puts a thumping 12" CompR sub behind your music. The rugged ported box was designed specifically for the sub, so you can count on getting maximum performance, no matter what kind of tunes you enjoy. The 12 CompR subwoofer comes equipped with a tough, polypropylene cone that stays rigid during intense play sessions so you hear accurate bass. A custom-designed back and top plate give the woofer plenty of room to travel, while the durable rubber surround helps to control cone movement during a heavy workout. This sub uses extensive venting in its heavy steel basket to shrug off heat, so you can count on reliable performance.
