Polk Audio PSWi225 200 Watt 8" Wireless Powered Subwoofer (PSWi225)
Introducing the Polk Audio PSWi225  wireless subwoofer. It's instant oomph! for your TV, with no wires or worries.
The Easiest Way To Enhance Your TV-Watching Experience

You're missing something, and you may not even know it. You're watching your TV; look how great your flat panel looks, how clean it is, mounted on your wall. You hear the music and effects and dialogue just fine from the TV's little speakers. Maybe you think: I wish this had more oomph!

No additional (and expensive) LFE cable needed; no audio wires needed at all. Put your subwoofer anywhere you want it, and sacrifice nothing for the convenience. Plug the sub into a nearby wall outlet, connect the transmitter, and you're done. Onboard Polk Digital Logic uses advanced auto-sensing to determine the signal your system is sending (LFE or Line Level), and it instantly responds, selecting the appropriate low-pass filter. The 2.4-Gigahertz Wireless Transmitter is state-of-the-art, interfaces easily with any system, and can be put anywhere in your room.

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—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.

• 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.
