Polk has announced a new wireless surround system: the F/X Wireless Surround. Polk claims that not only does the F/X not need wires, but it doesn't need multiple enclosures or dedicated power amps either.

Allegedly, it's designed to deliver surround sound from a single cabinet. The new F/X Wireless Surround employs Polk's Controlled Dispersion Array and Polk Digital Logic technologies to solve the installation problems posed by conventional multi-enclosure, wired surround sound speaker systems. A 2.4 GHz transmitter that connects to your home theater receiver or surround sound processor reportedly creates wireless 5.1, 7.1, and 9.2 surround operation.
Controlled Dispersion Array was first developed by Polk's analysis of head related transfer functions during the development of their SDA technology. A small transceiver included with the system connects the A/V receiver's surround channels to the F/X loudspeaker wirelessly.
When placed behind the listening area, the F/X's single enclosure loudspeaker system creates a convincing left, right, and rear surround stage, Polk claims. The F/X speaker system consists of four 2 1/2" full range drivers and a 5 1/4" woofer, powered by a compact multichannel 120 Watt amplifier. The system reproduces 5.1, 7.1, 7.2 and 9.2 surround program material and features a 3-position DSP control that optimizes the image height for floor, table and shelf placement.
