I have the klipsch promedia 5.1 deluxe. They kick ass when they work. 520 watts its was awsome. I found a place that will fix the amp for 90bucks. Apparently there is a design flaw that casued the amp to over heat and fail. I got lucky and mine lasted 4 years before it blew. I just got to remove the amp and send it out to texas to get it fixed. Its about 90 bucks. I paid 400 for them.
