Don't see any threads discussing these... have they passed into legacy status?
I have a dead 7.1 set and want to get it working again (to annoy the neighbors []). I sent an email to Klipsch earlier today, then joined this forum to try and get more info.
[edit] They are 5.1's. As the system has been put up in the closet for so long, I was looking at the sound card and error'd out!
