Some of you may remember me yammering on about my stereo, a 1970 Sony STR-7065A . . . Well, I've got a pair of pioneer bookshelf speakers, similiar vintage, that suffer from a combination of rotted-out paper cones/ blown. But I don't want to ruin the aesthetic of the setup with new speakers. Where can I buy the bare speakers to put into these cadinets? I thought for a while about car audio speaks, but I don't know if they will work wtih a home audio reciever, or maybe they are overkill. The speakers have a little ("tweeter"?) speaker on top and a larger one on bottom, which I assume is the subwoofer, its about 6 inches across . . So I'm looking for a pair of bare 6" subs for use in a home stereo. Where can I find a pair of them and how much should I expect to pay?
