I bought these speakers from newegg.com because they were offering a set of Energy outdoor speakers as a free bonus gift. I did a lot of research on 5.1 surround speakers in this price range and couldn't find anyone who said anything negative about them. Crutchfield has a video review of them as well.
The speakers sound great. Clear, crisp sound with good bass.
One problem: I set up the speakers and a few days later the center speaker woofer blew out. I called the Energy (Klipsch-the parent company) and they arranged for a replace to be sent out no questions asked. I didn't even have to send back the blown out speaker. I just emailed my sales receipt and address and a week later a new center speaker arrived. Very favorable experience!
If you are interested, act fast... as of 1/20/11 the Energy rep said they are being discontinued. I don't know what the replacement will be.
