Wireless High Performance Bass

Dollar for dollar there is no more economical way to add real drama and impact to your TV sound than with a subwoofer. It fills in the bass effects that your TV speakers cannot come close to reproducing. And for Polk high performance and compact wireless convenience, the PSWi225 is the logical choice.

PSWi225 Features:

The PSWi225 wireless subwoofer adds no clutter to your room at all, taking up less than a cubic foot of space and adding no unsightly wires, but it instantly adds a dimension of deep bass impact to your otherwise two-dimensional TV-watching experience. Clutter-free wireless bass for your compact home theater

The PSWi225 wireless subwoofer is also the perfect match for Blackstone TL and RM Series compact home theater systems, or our component SurroundBar®42 and SurroundBar50 theater systems, because with  the PSWi225 you can add 100-Watts of serious bass impact to movies and games, with no cable-length limits on where you put it.

Onboard Polk Digital Logic® in the PSWi225’s intelligent amplifier 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.

PSW enclosures are designed and engineered for perfect volume, minutely tuned for distortion-free low frequencies, and internally braced and damped to eliminate internal standing waves and other performance-robbing resonances.

Heavy duty MDF construction quality translates into better power handling, less wasted energy, and bigger, deep bass, plus the PSWi225 takes up just about one cubic foot of valuable room real estate.

Our engineers created a flared J-port design that optimizes laminar air flow for real bass performance at high listening levels and reduces turbulence, all the while retaining the PSWi225’s unobtrusive compact design.

Unique driver materials, speaker geometry and enclosure construction techniques are combined to produce cleaner, clearer sound. This is our patented Dynamic Balance® process, which enables the PSWi225 to perform effortlessly in high stress, big bass situations when you need them most.

PSW Series subwoofers outperform the competition with durable, resonance-free Dynamic Balance driver materials that stay stiff and move fast. You experience deep, musical low frequencies and thrilling effects with superior system blending.

By optimizing the woofer’s motor structure, voice coil alignment and suspension for smooth, unimpeded movement over a broad spectrum of the lower frequencies ensures the best, most efficient performance even at extreme listening levels. The Klippel optimizer makes this possible.

Easily accessible, professional-grade (unfiltered) line- and speaker-level inputs, and speaker level outputs, allow easy connection to any system.

Smart sensing circuitry knows when to turn itself on and off. Superior compression circuitry limits distortion at extreme volume levels. Intelligent amplifier also features adjustable low-pass crossover, phase switch & subwoofer volume controls to professionally control your bass output and the sub’s blending characteristics with your front stage speakers. Perfect system blending.

PSW Series subwoofers blend perfectly with systems composed of other Polk loudspeakers, especially TSi, RM and R/T/M Series speakers. so you can build the system of your dreams,

Unique design keeps your subwoofer stable and steady even at radical volume levels, for more efficient use of power. No more “escaped washing machine” syndrome.
