Do you think all my speakers have gone bad? Or, is it my receiver that has gone bad?
I have access to an oscilloscope, but I don't have another amplifier (or receiver) or another speaker (other than the 7), to test whether the speakers are bad or the receiver.
What could cause either of the two problems?
How old is the AVR?
Have you tried running in direct or straight mode?
You can just go to best buy and pick up an AVR. Test it out to see if the issue persists. If no, it's the AVR. If yes it's the speakers. Either way return the AVR and get one cheaper somewhere else if it's the AVR.
