Summary: Klipsch PC speakers are the best I've found yet. They cost a little more, but they'll last longer and sound a whole lot better than some cheap speakers. If price is an issue, find some nice used 2.1's. They're almost as good.
Summary: A true surround sound system if you have a sound card or receiver to send the 4 channel audio signal to it (if not you just get stereo sound). THX certified, uses Bash circuity for amplification. (2) 6.5" speakers in the sub is more total area than one 12" speaker. 400 watts allows plenty of power to the (4) satellite speakers. This system can't reproduce the lowest low like the Promedia 5.1 Ultra can but puts the Promedia 2.1 sub to shame.
