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.
-The absolute best-in-class performance from an American made subwoofer. The S7201 is a high output, high performance powered subwoofer destined to set the new standard in home theater bass.
-The S7201 subwoofer is powered by a 4000W RMS (8000W PEAK) built-in amplifier. A DSP based feature board includes the essential controls to properly integrate the subwoofer into your system.
-The Baltic birch plywood 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. The amplifier is mounted on the rear baffle.
-The S7201 houses four 18 inch subwoofer drivers, which are 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.
