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.
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.
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.
