Bold. Powerful. Custom. The CHS 212 Subwoofer is specifically designed for larger, custom installations where in-cabinet applications are a must. The CHS 212 Subwoofer is the counterpart to the highly acclaimed SubSeries 10 Subwoofer, and begins with a pair of hand-built, 12-inch long-throw woofers, designed to withstand the punishment and demand of theater soundtracks. The powerful 500-watt internal amplifier, extensive contouring and system-matching controls allow the sub to produce virtually unrestricted bass with unparalleled transient response, free of distortion.
