  • The S1801 subwoofer is powered by a 725W RMS (1900W PEAK) built-in amplifier with ICEpower® audio technology. A DSP based feature board includes the essential controls to properly integrate the subwoofer into your system.

    The MDF enclosure is heavily braced and assembled with rabbet joints for strong structural integrity. The enclosure is finished with a non-reflective and extremely durable textured material. An acoustically transparent fabric grille covers the front-firing 18 inch subwoofer driver. The amplifier is mounted on the rear baffle.

    The S1801 contains a single 18 inch subwoofer driver, which is capable of moving massive amounts of air. The 1.75 inch surround and poly cotton semi-progressive, high excursion spider allow the cone to move more than 2 inches peak to peak. The cast aluminum frame is mounted to the extremely linear and dynamic motor system, which provides the power to drive the cone in a symmetrical motion.
