Leave it to Logitech to once again raise the bar for computer speaker systems. The Logitech Z-5450 provides high performance sound with the innovation of wireless rear surround satellite speakers. The introduction of dual wireless rear speakers finally solves the common headache of having to run those long unsightly wires that run to your rear surround speakers. I've run into this problem myself and in the past it has caused me to either string cables all over the place or sacrifice a true surround experience by placing the rear surrounds closer to the front speakers.
