So, after an introduction to Polk with a pair of RTi6 speakers and a PSW110 sub hooked up to my PC, today I picked up a pair of what I believe to be RTA-12s. The seller described them as RTA-12Bs, but my preliminary research leads me to believe otherwise. They are shorter cabinets with black pedestal stands which he says are original (and I believe him, because he says he is the original owner). They also have a vertical black tweeter with 5514 1980 stamped on the back (which I think makes them Peerless?) and no ramp thing. Other than that, I would say they haven't been recapped, or molested/modified in any way. I have the caps, as he called them, for the external tweeter/crossover, but the MDF base decayed slightly and the posts are no longer attached, though I have all the pieces to put them back together. They're pretty clean, and sound absolutely fantastic hooked up to my Sony STR-GX9ES (don't know if this is a respected receiver, but these speakers sure sound sweet!) and I am stoked for $75.
What should I look out for with these? I've read a few posts about gluing (JB weld specifically, I guess) the speaker magnets on some Polks, would that be advised here? Should I worry about the caps and recap soon, or wait and do it when there's a little more room in my budget for caps.
Mostly I'm just excited to have entered the world of vintage audio, and with what to me sound like a fantastic pair of speakers. I'll try to get some pictures up as soon as possible to help you guys, and I'll keep researching these, I may answer some of my own questions.
