The Lowdown On Higher Performance

The all-new DSWPRO 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 DSWPRO Series as representing a new subwoofer performance standard. Here’s the lowdown:

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 or broad band dynamic compression, which squeeze the life out of the low end. What you hear is quick, precise bass output with minimal audible distortion, even at ground shaking volume levels.

Polk Room Optimizer™ (PRO™)

The DSWPRO 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: “Cabinet,” “Corner,” “Mid-Wall” and “Mid-Room.” No matter where you place your DSWPRO Series Sub, you’re assured great bass performance.

Real Big Bass
The DSW PRO 660 wi delivers more deep bass impact without cramping your style. Our most powerful subwoofer features a 400 Watt continuous intelligent digital amplifier to move its 12" Dynamic Balance® driver, filling even the biggest rooms with waves of tight bass. Experience thunderous explosions, powerful bass effects and precise musical bass response from a large subwoofer that still keeps a low profile.

Dynamic Balance®
Patented Polk Audio technology and construction techniques produce powerful, deep bass performance, especially when you need it most.

Klippel Distortion Analyzer
State-of-the-art optimizations to the motor structure, voice coil alignment and suspension ensure the best, most efficient performance at all volumes.

Expertly Crafted
Slot-loaded port design, lightweight polypropylene cones and durable rubber surrounds engineered for perfect volume, superior damping and deep, distortion-free bass response.

Maximum Efficiency
Proprietary intelligent amplifiers generate minimal heat and need less power to sound great, even at extreme listening levels.

Night Mode
Lower the subwoofer’s intensity quickly and easily—right toggle from the remote control.

Exclusive PRO™ Technology
Polk Room Optimizer (PRO) features four-way phase selection, four presets and an easy-to-read, blue status LED so you can adjust your subwoofer for optimal performance without leaving your seat.
