Polk snips the cord on PSWi225 portable wireless subwoofer

Haven't you heard? Wireless subwoofers are all the rage right now, man. Polk Audio is following the lead of Infinity and a gaggle of others by introducing the PSWi225, a "portable" cord-free subwoofer that can be added in to any home theater / stereo setup with utmost ease. The earth-shaker supports RF wireless signal transmission and delivers a 40Hz to 180Hz frequency response from the floor-firing enclosure. The unit itself measures in at 12- x 13- x 12-inches and houses a rugged long-throw Dynamic Balance co-polymer driver with Butyl Rubber surround. Curiously, there's no mention of the speaker size, though we are told that an active crossover system is included for those who like to fiddle. Check it this March for $399 (MSRP).
