Unless something is terribly wrong with the LogicTech. They usually sound good. I would blame the computer, it could be as simple as the audio settings in Windows, have you looked into it, most likely it needs reconfiguration. Do you have an Ipod? You can hook up the Front channels of the Logictech to test and see if the speakers are OK. It has been said the built in Matrix mode (an artificial surround option) sucks though and that really applys to anything out there that uses those silly two channel to 5.1 fake surround options (matrix, SRS, Q-sound, etc.). Turn it off. Consider getting Creative's Fatality sound card on your next build.
