Add Deep Bass Performance to Your TV Watching ExperienceEasy and Economical
You're missing something, and you may not even know it. Your TV looks great, but when you hear the music, effects and dialog from its little speakers you think: I wish this had more oomph! The Polk Audio PSWi225 Wireless Subwoofer is instant oomph! for your TV.
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. Offering a great way to dramatically improve the limited built-in audio performance of flat panel televisions in one easy step, the PSWi225 is the logical choice for high performance.
Compact, Powerful, Wireless
The PSWi225 Powered Wireless Subwoofer was developed to overcome one of the major objections to installing component home theater systems: subwoofer placement. The big boxes can be unsightly and may not fit with your room's décor. LFE cables are expensive and create visual clutter if the subwoofer isn't placed next to entertainment furniture. Taking up less than a cubic foot of space and free of costly, unsightly wires, the PSWi225 instantly adds a dimension of deep bass impact to your otherwise two-dimensional TV watching experience without cluttering your room. Experience the simple improvement of bass. It's already in your HDTV broadcasts and your DVDs. You just have to unleash it.
Powerful wireless transmitter goes anywhere in your room
Enjoy Wireless Convenience
The new PSWi225 Wireless Subwoofer makes enjoying home theater a lot more convenient. Use it on its own or pair it with another Polk home theater system package (sold separately). With the PSWi225, you can add 100 watts of serious bass impact to movies and games. Its powerful wireless transmitter frees you from cable length restriction and frees you to place it anywhere in your room--even inside furniture.
The compact, state-of-the-art 2.4GHz wireless transmitter interfaces easily with any system, can be hidden away and includes mounting options for placement either on-shelf, under-shelf or to the side or back of the entertainment stand. Plug the subwoofer into a nearby wall outlet, connect the transmitter and you're done.
Dynamic Balance technology tunes out distortion
Power You Can Feel
The powerful 100W 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, phase response and volume to control your bass output and blending with your front stage speakers for optimum bass performance anywhere you put the subwoofer.
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.
Flared J-Porting system improves bass detail and definition
Onboard Polk Digital Logic uses advanced auto-sensing to determine the signal your system is sending (LFE or Line Level) and instantly responds, selecting the appropriate low-pass filter. The PSWi225 doesn't call attention to itself until it senses a signal and snaps to attention, allowing you to experience its big bass output.
The 8-inch subwoofer driver incorporates patented Polk Audio Dynamic Balance technology to tune unwanted resonance and distortion out of the lightweight copolymer driver for more clarity and low-frequency detail, bringing you pure, distortion-free sound. The driver features a polymer composite cone, inverted dust cap and rugged butyl rubber surround that provides superior rigidity and damping properties.
Klippel Optimized Woofer
Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers have optimized the woofer's motor structure, voice coil alignment and suspension for the best possible performance, even at room-shaking listening levels.
Computer modeling enabled creation of a flared J-Port design that optimizes laminar air flow. The result is superior bass detail and definition at a variety of listening levels, as well as enhanced integration with the main speakers, while retaining the PSWi225's unobtrusive, compact design.
