I recently purchase a set of Klipsch reference premiere speakers with the Denon AVR X4500H receiver. The front pair is the RP-8060 setting up for 5.1.4. After running Audyssey my right sound only have sound coming from the tweeter but not the woofers. It’s not the speaker problem because if I switch the left and right speakers, the right side still have the problem but the left side works fine. I tried resetting the receiver and reconfigure but same. I tried to change many different wire same problem. Any suggestions what else can I try before I call Denon to service my receiver? Thanks.
