Bought 4.1 two weeks ago, after waiting years for Klipsch to catch up with PC audio technology. I always know they makes the best speakers. Had to return the 4.1's. Subwoofer overheated. Did not have any confidence in the replacements and with the news of the 5.1's on the way it was too much to take. I bite the bullet, so to speak, and bought the Quintet and a receiver instead, hooking the lot to the computer. Best decision I ever made in matters of that nature. To put it mildly. It ROCKS. You guys should try that setup.
