My 8000s do it too. I have the rf-500 II speakers also, I hooked them up to the front terminals on the receiver, I do get the channel test to work on them , and they play music, the 8000s will not do the sound test, nor play music on the front terminals, or any other terminals. I'm wondering if someone hooked up the wires inside the speakers wrong, like in the crossover area I'm calling Klipsch support on Monday during their business hours.
