I recently acquired a minty pair of R.T.A. 12C speakers as well as a pair of equally nice R.T.A. 11 (or as some call them Monitor 11) loudspeakers. Both have the black Peerless tweeters, as I swapped out the Polk brand silver-faceplated SL-1000's from the 12C's for Peerless. Currently the 12C's are hooked up to our Onkyo A/V receiver (TX-SR607) and they sound much better than any speakers I've ever owned. However, I'm not cranking the volume since this amp is not intended to drive 4 ohm speakers. I don't want to damage our receiver and certainly not these vintage beauties! Although they're currently used as the front speakers in our 5.1 channel system, their main use is in 2ch stereo mode when we listen to vinyl records using a Cambridge Audio phono pre.
My question is... If I want to properly drive just one pair of these speakers (the RTA12C's) using our current A/V receiver, would the addition of a used Hafler 9300 Transnova via the pre outs do the trick? There's also a Carver PM-700 that I'm considering. I believe these power amps are compatible with 4 ohm speakers. The RTA 12C is rated at 4 Ohm and the RTA 11 is rated at 4.5 Ohm. I'm open to other power amp suggestions though. If need be I guess I could possible even consider a completely different pre amp/power amp combo. However, my budget max is $400-$500.
Thanks in advance. I'm new to Polk and very excited to hear the full potential of these beauties!
