Next to video, sound is probably one of the most important aspects of a PC. And if sound is important to you, it should be of decent quality too. Today I'll be looking at the Logitech Z Cin=E9ma Advanced Surround Sound System. Although not a true surround sound setup, which typically include six, seven or more speakers laid out in a circle around the listener, this is a 2.1 setup, with two satellite speakers comprised of dual mids and tweeters, and a single high-power subwoofer for the bass.
