Polk Audio DSW PRO 660wi Powered Subwoofer With Remote Control



  • The DSW PRO660wi uses a 12" 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.

Klippel Optimized Woofer:

  • 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.

Class D Amplifier:

  • The subwoofer is powered by a high-current class d amplifier producing 400 watts RMS power (800 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.

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 sub-woofer system without relying on slow responding feedback techniques.
  • What you'll hear is quick, precise bass output with minimal audible distortion, even at loud volume levels.


  • The DSW PRO660wi features a bass-reflex enclosure with non-resonant mdf construction and internal bracing for deep bass impact with superior detail and accuracy.
  • The subwoofer's enclosure's durable onyx black finish can be painted to match your room decor, if desired.

Downward Radiating Slot Port :

  • The DSW PRO660wi features a downward radiating slot port which lessens turbulence, noise and distortion.
  • The result is deep, clean and accurate bass.

Video Shielded:

  • The DSW PRO660wi is magnetically shielded for placement near video monitors.
  • You should still allow at least 18" of space between your subwoofer and any tube television.
  • Lcd, dlp and plasma tvs are not affected by magnetism.

Frequency Response:

  • The overall frequency response for the subwoofer is 20-160hz, and the -3 db frequency response is 25-125hz.

Repositionable Feet:

  • The DSW PRO660wi features repositionable rubber or spike feet which allow you to orient the subwoofer on its "Back" to turn it into a front-firing woofer when you want to hide the subwoofer away in cabinets.
  • There is an optional woofer grille (item # 107dsw600g, sold separately) available when the subwoofer is used in a front firing application.


  • The remote control may not operate when the subwoofer is placed in a cabinet with the driver facing into the room. If this occurs, adding an ir repeater will enable the remote control to communicate with the subwoofer.


Ir Wireless Remote Control:

  • The DSW PRO660wi comes supplied with a credit card sized ir wireless remote control which operates the following subwoofer's controls - volume, mute, phase, night and polk room optimizer.
  • All commands are sent to the subwoofer via ir control.
  • The ir receiver is located on the front of the subwoofer when the subwoofer is its downward firing configuration.
  • There is a blue led behind the woofer's logo badge which blinks to confirm the subwoofer has received and responded to the remote's instructions. The led feature can be turned off.
  • The subwoofers crossover setting must be set using the controls located on the rear panel of the woofer.

Polk Room Optimizer:

  • The DSW PRO660wi's remote control incorporates the polk room optimizer (pro) feature.
  • The polk room optimizer feature allows you to place the subwoofer where you want it in your listening room.
  • Based upon the four most common room placements for subwoofers, the polk room optimizer maximizes sound quality for you, smoothing out the bass response that a particular room placement creates.
  • There are four push-button room equalization presets on the remote that correct for room boundary effects for typical room placements: "Cabinet," "Corner," "Mid-wall," and "Mid-room." the result is great bass performance no matter where you place your dsw pro 660wi subwoofer.

Night Mode:

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

Volume Control:

  • The DSW PRO660wi has a push button volume control to adjust the volume of the subwoofer relative to the other speakers in the system.
  • The volume is adjustable from 0 to 40. The blue led on the front panel will indicate the volume level using a combination of short and long blinks.
  • The volume can also be adjusted using the supplied wireless remote.

Phase Switch:

  • The subwoofer's ir wireless remote features a phase control which allows you to select 0-degrees (normal), 90-degrees, 180-degrees (reverse) or 270-degrees.
  • This control enables the subwoofer to blend more seamlessly with your main speakers.
  • If the bass sounds muddy or unclear, using the phase control can sometimes strengthen the bass "Attack."

Low-Pass Filter:

  • The DSW PRO660wi offers a continuously variable low-pass filter, adjustable from 60-120 hz. The cut-off frequency must be manually set from the subwoofer's control panel.

3-Way Power Switch:

  • The subwoofer has a 3-way power switch on the rear panel.
  • You can select "Auto", which turns the unit on automatically when an input signal is received and off 15 minutes after the signal stops; "On", which keeps the unit on and "Standby", which turns the unit off.
  • The led power indicator glows green when the unit is on, red when the unit is off and yellow during standby mode.


LFE (Unfiltered) Input:

  • The DSW PRO660wi has a gold-plated mono rca lfe (low frequency effects) input.
  • This input should be used when connecting to a receiver with a filtered subwoofer output, such as those found on most home theater receivers (check the receiver's owner's manual).
  • The lfe input bypasses the subwoofer's built-in low pass crossover.
  • if the receiver's subwoofer output is unfiltered, you should use either the left or right line input of the subwoofer.

Line (Filtered) Inputs/Outputs:

  • The subwoofer has gold plated left and right rca line level inputs.
  • The inputs are for use with electronics featuring unfiltered "Pre out" jacks (example: a separate pre-amp processor with a separate amplifier).
  • It may require "Y adapters" to connect the left and right outputs of the pre-amp processor to both the subwoofer and the power amplifier.
  • The line outputs allow you to send a filtered signal to a power amplifier to drive bookshelf speakers.

Speaker Level Input/Output:

  • The subwoofer has 5-way binding post connections for front speaker level input and output.
  • The subwoofer's low-pass filter takes the low frequencies (based on the setting of the filter) and sends it to the subwoofer.
  • The speaker level outputs send a filtered signal to your connected speakers.
