Logitech's new Speaker System Z906 ($400) is intended to give you the flexibility to set up your entertainment system the way you want to. It allows you to connect up to six audio devices (any more is just overkill) simultaneously, including your TV, DVD, DVR, Xbox, PS3, Wii, iPod, iPhone and more. The Z906 includes five wall-mountable satellite speakers, a woofer, a stackable control console, and a wireless remote for controlling your audio right on the couch.
