Get the Klipsch 5.1 THX ones. They run from $300-$350 but they are worth every penny. In my opinion they have the best sound quality of any speaker set I've ever heard. Clear, crisp, and beautiful sounding with enough bass to make the room vibrate if you so choose (not the obnoxious booming stuff either just pure quality bass tones). if you don't need surround then go for the Klipsch 2.1 (the ones I am currently using due to lack of funding). They are just as good as the 5.1 but only cost about $200. The Klipsch blow the THX certified Logitechs out of the water in terms of sound quality. Don't get me wrong, the logitechs are some of the best but Klipsch is head and shoulders above everything else out there.
