We don’t use cheap paper cardboard woofers. This is the real deal and part of why PSW Series subwoofers outperform the competition.

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 bringing you the best possible performance even at extreme listening levels.

A Polk perfected method of analyzing a speaker’s microscopic behavior with laser Interferometry. Polk engineers can tune out unwanted resonance and distortion with the right combination of materials, geometry and construction techniques. This brings you pure, distortion free sound.

Line- and speaker-level inputs, and speaker level outputs allow easy connection to any system.
