Polk Audio DSW PRO 440wi Powered Subwoofer
The Polk DSW PRO 440wi Powered Subwoofer uses an 8″ Dynamic Balance composite polypropylene cone driver for deep, accurate response with low distortion. For a smoother response and improved durability, the woofer utilizes a rubber surround. By using a state-of-the-art Klippel Distortion Analyzer, Polk Audio is able to optimize the woofer’s motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels. The subwoofer is powered by a high-current Class D amplifier producing 180 watts RMS power (300 watts Dynamic Power) that supplies clean power for loud bass and a wide dynamic range necessary to recreate a life-like experience in your home. The efficiency of a Class D digital amplifier translates into high-power, and cool, reliable operation with low distortion.
