Before you determine that the tweeter is blown remember that the RC-10 has dual biwire binding posts. So make sure it's not something as simple as the shorting straps being loose. Try disconnecting the shorting straps and just connect the avr output to the top (tweeter) binding posts and see if it makes noise.
Thanks for the comments and suggestions. Still waiting to hear back from my email to Energy from the other day. May send them a follow up one to see if they received my email.
Also, I never play the speakers loud, usually around -45, since I live an apartment with walls that seem to be made of paper. I don't like it when others blast their movies/music so I can extra care to make sure I am not playing anything louder than -40.
So, another interesting thing I noticed is that the tweeter comes on sometimes after about an hour or so of playing music and then goes away. Sometimes I hear a slight static/popping noise. Also, I can "force" the tweeter to come on by increasing the volume from -10 to -5 and it will come on and produce sound.
Per your instructions batpig, I connected the avr directly to the top binding post and removed the metal connecting piece and no sound is produced from that speaker until I increase the volume to -10 to -5 to force it to come on. I can then adjust the volume to whatever level and it will stay on but sound has a "hiss" to it at -10 and above.
Given this new info, could it be anything else besides the tweeter?
