RTA 12C's upgraded for forum member, w/ pics

[turbomustang84]

i use either my Mitsubishi DA-A10DC which puts out around 160 watts into a 4ohm load or my Harman kardon citation 19s but either amp does fine as long as the eq is out of the loop ,so when i drive them above half volume i have to shut the eq off .

Late to the party, however never seen anything like it. Absolutely the envy of every reader on this forum.

Yes, this thread was the inspiration for the restoration work I did on my 11's. If I've viewed this thread once, I've viewed it a hundred times. Ideas I blatantly stole include the use of T-nuts and stainless steel cap-head machine screws, blue/black/white heat shrink on the internal wiring, damping material on the MW and passive radiator baskets, and just the general motivation to go for it and re-cap my crossovers. I realize that a lot of these ideas may not have originated from this thread, but nothing else lays it out and documents everything so well in one place. My results may not be so professional, but the improvements are tangible and definitely worth it. Mad props to geoff727.

Wow!!
Just joined the club a week ago after I got my first set vintage Polks (monitor 10b's) and have been looking around for parts for my damaged RTA 12B'S. Came across this and read every single post and looked at every single pic.
Am I stepping over any lines asking how much this project cost? What are the chances of getting you to upgrade my crossovers and wiring?

Another mod question. Has anyone ever done the bi-amp mod on these?

Not at all (to the first question). To the 2nd question, if you're serious about doing them, send me a Private Message when you get ready. The price level on these can run a huge range, due to the fact that there are quite a few capacitors on the boards and there are so many out there to choose from with a huge variety in price. Somewhere I have a list with various upgrade levels that I generated for Roger (the owner of the speakers on this thread). Always happy to do work for a fellow Polk fan.
