I picked these RTi10's up on craigslist. I've had them for about 3 weeks now. I'm not an audiophile. So I really didn't notice a difference in the speakers, till about a week ago. The right side didn't seem as loud. I just bought a new Yamaha RX-V1900 receiver and now I can hear the difference even more. I put a paper towel roll. Up to the right and left tweeters. After the test I don't hear any thing coming out of the right side speakers top tweeter. So I think it's bad but I'm not sure. Is there and more tests I should make. Or do I just try and find a new set of tweeter?

Oh yea and when I play "Pink Floyds" Dark Side of the Moon. The 3rd song "Time" (When all the bells are at their loudest). It crashes my receiver. It's starts back up and I see "check Sp wires" flashing and then it plays as normal. I'm Lucky it hasn't blown the receiver yet. Would a shorted out tweeter cause the receiver to do this?

I'd also like to know what size allen wrench it takes to remove the tweeter. I've gone thru every one I have and none seem to fit.

I was redirected to post over here. Since my original post was in the 2 channel section.

Any help would be appreciated.
