And once you experience the simple improvement of bass… Well, then you (and your family) may be much more receptive to exploring the excitement of multi-channel home theater sound. (It's already in your HDTV broadcasts and your DVDs. You just have to unleash it. We can help.

Clutter-Free Wireless Bass For Your Compact Home Theater

The PSWi225 Wireless Subwoofer is also the perfect match for your RM Series Compact Home Theater System or your SurroundBar Theater System. With it, you can add 100-Watts of serious bass impact to movies and games, with no cable-length limits on where you put it; the PSWi225 has a powerful wireless transmitter that allows you to put it anywhere in your room (even inside furniture). It doesn't call attention to itself, until it senses a signal and snaps to attention and you experience its big bass output!

Power You Can Feel—The powerful 100-Watt onboard amplifier features active crossover controls you can use to further tweak your bass response for your room and your custom placement. Adjust the low-pass filter settings, the phase response and the volume for optimum bass anywhere you put the sub.

Compact Size—Takes up about a cubic foot of space: 12.5"W x 13"H x 12.5"D

Floor-Firing impact —For the deepest bass possible, the heavy duty, non-resonant MDF cabinet is internally braced and ported, and fires an 8-inch Dynamic Balance driver down toward your floor, using the flare of the port to radiate waves of low frequency. You'll feel this bass in the seat of your pants.

Superior Polk Audio Technologies

Patented Dynamic Balance® technology tunes distortion out of the lightweight, copolymer driver for more clarity and low-frequency detail. Klippel Optimization ensures reliable performance from the woofer's motor structure, voice coil alignment and suspension, even at room-shaking listening levels. Our rugged Butyl Rubber Surround stands up to the demands of today's active subwoofer; and the computer-enhanced design of the flared port smoothes air flow, increasing efficiency and revealing accurate, musical bass.

Dynamic Balance—Exploded WooferA 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.

Klippel Optimized Woofer —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.

J-Port Design—The laminar flow of air through a subwoofer's port is necessary to achieve clean, impactful bass at a variety of listening levels. Laminar flow is a function of the port's length and its cross-sectional area, two variables that, in the PSWi225, were especially challenging to work with given the subwoofer's compact size and its target tuning frequency of 38Hz. Using computer modeling, Polk engineers created a flared J-Port design that optimizes laminar air flow for real bass performance at high listening levels and reduces turbulence, all while retaining the PSWi225's unobtrusive compact design.
