The all-new DSW PRO Series represents more than a significant step forward in subwoofer performance. Rather, with the incorporation of two proprietary Polk Audio technologies that offer clearly discernable benefits, you might want to think of the new DSW PRO Series as representing a new subwoofer performance standard. Feed Forward™ distortion suppression technology This technology maximizes acoustic output as it reduces audible distortion. Feed Forward is a zero latency system that maximizes dynamic output of the subwoofer system without relying on slow responding feedback techniques. What you hear is quick, precise bass output with minimal audible distortion, even at ground shaking volume levels.


    The DSW PRO Series remote control incorporates the Polk Room Optimizer (PRO) feature, four push-button room equalization presets that correct for room boundary effects for typical room placements: “corner,” “short wall,” “long wall” and “mid-room.” No matter where you place your DSW Pro Series sub, you’re assured great bass performance

  • Klippel Optimized woofer
    By using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer’s motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels

  • Class D Amplifier
    The efficiency of a Class D digital amplifier translates into high-power, and cool, reliable operation with low distortion

  • Downward Radiating Slot Port
    Lessens turbulence, noise and distortion; you get all the bass--every time

  • Front Firing applications
    Repositionable feet allow you to orient the subwoofer on its “back” to turn it into a front-firing woofer when you want to hide DSW Pro Series subs away in cabinets

  • LINE and SPEAKER level inputs
    Ensure easy hook-up compatibility with virtually any system; Unfiltered LFE Input for use with low-pass filtered subwoofer output jacks

  • Amplifier features
    Adjustable Low-Pass Crossover, Phase Switch and Subwoofer Volume Control to more easily control your bass output and the sub’s blending characteristics with your front stage speakers

  • Signal-sensing “smart amp”
    Auto ON/OFF Circuitry “knows” when to turn itself on and off

  • Rock-solid MDF enclosure
    Suppresses enclosure panel resonance for distortion-free, accurate response.for safe placement near video sources

  • 5-way Binding posts
    Give you lots of hookup versatility and tight, snug connections

  • Remote Control

    • Adjust subwoofer volume

    • 4-button phase control (0, 90, 180 and 270 degree settings)

    • 4-button Polk Room Optimizer (PRO™) presets

    • Mute function

    • Night function compresses the dynamic range of the woofer’s output, so you hear low-level bass detail at lower volumes

    • Reset button restores the woofer’s settings to factory presets

    • Blue LED behind the woofer’s logo badge blinks to confirm the subwoofer has received and responded to the remote’s instructions. The LED can be turned off
