I just picked up a super clean set of RT 55's with a center sub & a Thrift store for $50.00. I had a feeling something might be wrong with them at that price but bought them anyway. Sure enough, one of the main RT 55's has a blown tweeter for sure & it looks like I can get a replacement through Polk. My question is, as I'm trouble shooting & before I send for the new part, is there anything more I should be looking for that may be wrong , ie bad crossovers etc? I'd rather fix it right the first time. Thanks.
One other thing while I have your attention, I'm using a Harmon Kardon AVR 120 Amp. I've never had a center speaker hooked up. I can't get it to select and drive all three speakers at once. It's either the two bookshelves or the center, but never all three. I have them wired correctly. Any suggestions?
Appreciate you all being here. thanks in advance for your help.
