POLK AUDIO SUBWOOFER PRO550WI

DSW PRO 550 wi Features:

• DSWPRO Series enclosures are designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies, and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances.
• Polk intelligent amplifiers require less power to sound great, use power more efficiently and know when to stand down (especially at low volumes or in "Standby" mode); even at extreme listening levels, it's a wonder of digital high efficiency, bullet-proof reliability and minimal heat generation.
• Feed forward distortion suppression technology enables us to set our performance limits much higher than normal, much closer to the actual (theoretical) maximum output of the subwoofer, with no risk of excessive distortion or damage.
