    Smile tweeter update for my rta12b's

    Okay, my last post was going to another universe so to get back on track can any of you techno geeks tell me what mod's will be necessary to upgrade my RTA12 B's crossover and what speakers I shoud use for replacing the tweeter which has 5514stamped on the back? It looks like a black cloth dome with a vee shape groove on the front for the coil wires. Plus does anyone know what woofers I should order to replace the existing ones or if they work leave them alone?

    That sounds like the "Peerless" tweeter, I would leave it alone. Same for the woofers.

    Is there something special about the peerless tweeter that it's sound is superior to the replacement driver?

    The Peerless tweeter is extremely smooth. Any gains you would get by upgrading to the RD0194 would be modest if any. Besides, the peerless mounting pattern is quite different from the RD0194, so you would need to do some woodwork.

    Geoff727 did the best DIY write up for RTA 12's I've seen: http://www.polkaudio.com/forums/show...light=geoff727

    Xover component values are in the schematics posted in one of the stickys. It's good policy to see what Polk actually used though, so check your caps and resistors for actual values.

    Good luck!
