Everything USB posted a review on the Logitech Z Cinema SRS TruSurround HD USB Speakers

Everyone knows that nothing can beat the quality of sound that you get from a 5.1 surround system. Unfortunately with the aural bliss comes the headache of cable clutter and space constraints when trying to find a place to put those rear speakers.

Featuring SRS TruSurround HD, the Logitech Z Cinema offers surround sound in a 2.1 speaker configuration. Full review in the link.
