The TechZone has posted a review of the Z Cinema Home Theater Speakers from Logitech
While a 5.1 speaker system is nice and all, not all of us want to deal with the messy wires and cables that would be involved in managing six speakers. Providing us with surround sound without the need for rear speakers is the Logitech Z Cinema Advanced Surround Sound System. It may look like your regular run-of-the-mill 2.1 speaker system, but those two satellites are actually capable of producing virtual surround sound via SRS TruSurround HD technology.Logitech Z Cinema Home Theater Speaker Review
