"Dented tweeters — Does not affect sound "

Yes, if God meant for tweeter domes to be dented, he would have made them that way.

"If tweeters sounded the same with dented diaphragms wouldn't the speakers manufacturers dent them in advance?"

????
Sorry V but I think your logic's a little fuzzy. Should auto or furniture manufacturers, just to name two, whose products would function perfectly if dented adhere to this line of thought?

Thanks Markpao, I'm going to offer that fellow double his asking price. ;-)

I've always held A'goners (as individuals) in a higher regard than on other listing sites, and I hate the thought of this turning into a flea-bay alternative where dented tweeters don't affect sound. Or "8/10 rating" amps that power up, but don't send a signal to the speakers (but don't worry, because its a cheap and easy fix).

And don't get me started on "rare" items. :-)
