Get to know this product.

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.

Gold-Plated Terminals

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.
