Best matched for RM and SurroundBar series or compact speakers from other manufacturers, the Polk Audio PSW111 compact powered subwoofer features an 8-inch composite woofer that packs a punch larger than its size would suggest--delivering powerful, accurate and musical bass at an affordable price. It measures 12-1/8 x 11 x 13 inches (HxWxD) and it has a continuous power rating of 150 watts (with 300W dynamic power rating).
All woofers (except for PSW10) feature a floor coupled downward firing port. This configuration brings you maximum bass impact while keeping the front of the cabinet as low profile as possible.
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.
LFE, line and speaker level inputs, and speaker level inputs allow easy connection to any system.
PSW Series subwoofers use intelligent amplifiers. This means, not only can they put gobs of power to your woofer, they'll use very little power at low volumes or standby mode.
