Bring the noise with the heavy-duty Dual XNBP12D enclosed subwoofer, which features a carpeted enclosure, plexi subwoofer viewing window, and unique blue illumination. The patent-pending illumiNITE technology constantly illuminates the subwoofer with blue LED lights when it is in use. This box makes a simple and easy add-on for existing systems with no crossovers needed. It provides 600 watts of RMS power and 1100 watts of peak power. Dual's enclosure utilizes a specialized tuned-port computer-aided design to increase the output efficiency. The nailed and glued construction with added bracing is used to eliminate enclosure movement caused by high sound pressure levels. Other features include dual 12-inch Low-Q optimized drivers for loud, accurate bass, four-port dual chamber design, and a mirrored/diamond-plated chamber.
