Kickers Solo-Baric L5 S10L5 10" woofer comes out swinging with a sturdy steel basket, copolymer cone, and durable Santoprene rubber surround for bass that just wont quit. The Inverted Structural Dome (a hallmark of Kicker subwoofers) replaces the conventional dustcap, locking into the cone for unrivaled structural integrity at blasting sound pressure levels. Perimeter venting pumps hot air away from the voice coil for cooler operation and lower distortion. The dual voice coil design lets you wire your sub for high output (2 ohms) or multiple woofer configurations (8 ohms).
