RTA 12B specs and other things

Hey y'all,
I am wondering if anyone out there is able to tell me what impedance
the RTA 12B is rated at, and also what is the stated power handling
capacity?
I am interested as I am trying to compare the RTA 12B to my recently
acquired set of SDA 1C speakers.
Oh yeah, I live in Sydney, AUSTRALIA and did scout around here a few
months back trying to figure out a way to get me a pair down here
somewhere. Seems they are rare as the proverbial, so I ebayed it and
got myself some minty SDA 1C's which were in the original boxes.
I had them freighted down here by a friend who works for Fedex and
gets the 75% staff discount. Sweet.
Havent anywhere to hook them up yet, as I havent moved into the
house that I have bought. I did give them a run in the old bedroom
using my Yamaha AV receiver and they sound like they will crush the
neighbourhood!
Am I greedy for wanting to get a pair of SRS? Or should I just be
content with what I have for a few years? Haha.
Anyway enough from me. Glad to be a POLK OWNER NOW!
Cheers,
Alex.

Welcome Alex.
The RTA 12C is advertised as 92dB, 4 ohms and 10-500 w/channel. I'm not sure what the differences are for the RTA 12C. The RTA 12C manual can be found here: http://www.polkaudio.com/downloads/manuals/home/12CManual.pdf
Both the RTA 12 and SDA 1C are highly regarded models around here. The SDA 1C manual can be found here: http://www.polkaudio.com/downloads/manuals/home/sda1c_2b_crs+_manual.pdf
Sounds like your friend is treating you right so don't forget to return the favor. With a shipping discount like that you should bring another pair over.
Use an amplifier with 150+ w/channel of high current with these. Receivers and weak amps won't open these up to their best sound and can pop drivers with dirty power when the amp is overdriven. To be safe, don't go past 10 o'clock on the dial with that receiver. If you find the tweeters sound harsh to your ears after a few hours of listening, Polk Audio has updated tweeters available that most people prefer.
Some of the crossover components have a life expectancy of ~20 years. There are posts here with details for rebuilding the crossovers, use the forum search feature (above in the blue bar) to read them over. If the tweeters cut out when playing at loud levels, you may need to replace their equivalent of a fuse called the polyswitch. Search will bring up info on these. There are also links to related posts listed at the bottom of each page. -
Hey man,
Thanks for the stats. Point noted with the Yamaha receiver.
Ill look into the technicalities of the upgrades. I will try and
get another pair out here while my friend can still ship on
the cheap!
Cheers,
Alex.
