DSW Pro Series Subwoofers

The Best Bass Anywhere For movies, it makes action explosive. For music, it adds depth and emotion. So we've always prided ourselves on the performance of our powered subwoofers. Harnessing advanced, proprietary technologies, like superior bass venting (that stops performance robbing turbulence) and heavy duty enclosure construction (for more energy efficiency), we build the subwoofers we want to have in our own homes. You get that same performance edge. Supports both downword and front firing orientations.


  • Carpet spikes and adjustable rubber feet
  • IR Remote
  • Optional grille for forward-firing orientation


Internally Braced Enclosure

DSWPROwi 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. Heavy duty MDF construction quality means better power handling, less wasted energy, and bigger, deep bass. Classy black finish is paintable, to match any decor.

Intelligent Amplifier Technology

High power, high current, and smart to boot. Polk intelligent amplifiers require less power to sound great, uses the power you give them 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. Smart sensing circuitry knows when to turn itself on and off. Superior compression circuitry limits distortion at extreme volume levels. Compact size keeps enclosures small.

Feed Forward Distortion Suppression Technology

We wanted to design a subwoofer that avoids distortion and damage, but that preserves as much low end dynamism and as much output capacity as possible. We wanted the biggest bass, with the least distortion. This has always been difficult, because it's a fact of loudspeaker life that if you play it too loud, it will distort. To change that fact, we programmed our digital subwoofer processors with a mathematical model that knows in advance how the woofer's acoustic system will respond to the output signal from the amplifier. The digital processor monitors the amplifier for signal combinations that would cause distortion or damage, and alters only that part of the signal required to maintain safe operation. It does this instantly, before the signal ever gets to the woofer driver itself, so there's no correction time delay, and no need for limiting or compression. It's called feed forward distortion suppression technology, and only Polk has it. It allows 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.

Polk Room OptimizerT (PRO)

The most important question when it comes to subwoofers is, where do you put it; how do you compensate for room size, room setup, placement position? With "one size fits all" subs, you'll be forever shifting positions to try to find the bass sweet spot. With the DSWPROwi Series, you can choose one of four preset "room optimizers" from the remote controller, and Polk's exclusive PRO technology programs in the optimal bass and blending setting for your room.


  • Compact subwoofer delivers smooth, powerful bass from anywhere in the room
  • Feed forward distortion suppression technology allows higher maximum output without distortion or damage
  • Innovative front-firing mode lets you place the subwoofer just about anywhere
