An update on my RC-10 tweeter situation. Also, I use spade banana plugs for the rear RC-10s and Silverback banana plugs for the two RC-70s and the LCR.
Today per some suggestions from other forum members, I took out the tweeter to double check the connections and also unscrewed the binding post and made sure any connections in that area were also tight. The wires on the backside of the binding post are soldered so there wasn't much I could do there. On the front tweeter, I made sure the two wires were tightly connected to the tweeter speaker posts.
After screwing everything back in, I tested out the tweeter only and it worked immediately with just the tweeter connected to the avr. So I then reconnected the metal connecting piece between the top and bottom binding posts and connected the avr spade plug in the bottom posts, played some music, and was able to hear sound coming from the bottom speaker and top tweeter.
I then wanted to test the Audyssey aspect to see if I could hear the "chirp" or not so I moved the speaker closer to the AVR and used the wire from the Front Left Speaker because that is the first speaker Audyssey tests. The front speaker wire is connected by regular banana wire and this is where I think I'm starting to pin point the issue.
I plugged the wire into the bottom post of the RC-10, ran the Audyssey test, and disappointingly, the "chirp" was not there. So I grabbed the RC-10 to look at the back and while doing this, the "chirp" suddenly came back. So I ran Audyssey again and the chirp was still there, ran Audyssey again but I moved the speaker a little and now the chirp was gone.
So I started to wiggle the banana plug on the bottom binding posts and noticed that while I was wiggling the red or + binding post, I could cause the Audyssey "chirp" to appear and disappear depending on how I held the banana plug.
That is the latest in trying to figure out what my issue is with this RC-10. The bottom binding posts looks to be the culprit and since everything look soldered on the inside, I don't know what my next step would be.
Still haven't heard from energy so I'm gonna call them again tomorrow with this update and see what they think and what steps to take.
