Logitech Announces 5.1 Surround Sound Speakers with No Cables

Logitech announced Wednesday what it said is the worldis first THX-certified 5.1 speaker system with digital, wireless dual rear speakers.

The Z-5450 digital system has independent, wireless rear speakers can be placed anywhere within 28 feet of the speaker system control center, requiring only a power outlet. The speaker deliver 315 watts of THX-certified power.

Z-5450 digital systemis two rear speakers each feature their own built-in wireless receiver and power amplifier. All each rear speaker needs is a power outlet. The system uses digital, 2.4 GHz wireless technology, with adaptive frequency hopping, to minimize any chance of interference. Any potential performance problems due to interference are virtually eliminated due to the fact that the system intelligently sends redundant wireless transmissions to each rear satellite; if one data stream is lost, a second identical stream is captured. And the Logitech dual wireless speaker solution has very low latency, less than 20 milliseconds, which is imperceptible to the human ear.

The system includes inputs for up to seven multimedia devices, which makes it versatile for use with a PC or in a living room entertainment center. The system features chrome satellites -- with optional cloth grills -- that have rotating stands, which make them easy to mount to a wall or to position on a table or desktop.

The Logitech Z-5450 digital speakers will be available in the U.S. beginning in September for a suggested retail price of US$499.99.
