It is a small subwoofer system. It is designed to be used with CL-28, CL12 and CL-15 full-range speaker systems, suitable for those occasions that require higher low-frequency output and larger system dynamic range. CL-18B's high-power bass system can provide high sound pressure and low distortion output with low distortion during long hours of work. By using an effective heat dissipation mechanism, the louder speaker can maintain a high low-frequency output under extreme conditions, avoiding the power compression loss that often occurs in other systems.
