Unleash your home theater
Create the very best home theater experience with a powered subwoofer from Power Sound Audio. Energize your room with fast, dynamic bass and cinema quality sound.
-Developed for the discerning audiophile, the S1811 powered home theater subwoofer is ready to pound your chest and rattle your windows. The S1811 is a relatively compact subwoofer with the power reserves to pack a serious punch.
-The S1811 subwoofer is powered by a 960W RMS (2100W 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 S1811 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.
