Unobtrusive, handsome, and powerful, the C4 subwoofer provides an incredible bass output with immaculate control. With a 200W on-board amplifier driving a 200mm (8in) front-firing bass cone, the C4 is engineered to minimise distortion as meticulously as the rest of the range and adds effortless depth and weight to any performance. The exceptional acoustic definition you experience depends on the recorded signal being perfectly transmitted, so to eliminate the risk of tarnishing, the binding posts of the C Series are gold-plated.
