    While efficient, the RTA-12s require a high current amplifier in order to get the best performance out of them. I had a 100-wpc amp that was lightweight. Sound was horrible. I connected the speakers to a Acurus DIA-100 (also 100-wpc, but with a bigger power supply) and it was a magnitude increase in sound...

    They're rated 4 ohms nominal impedance, and can be driven with 10-500 wpc. The lower number suggests good sensitivity, but I would definitely go with as much clean, high current power as you can muster. It makes a huge difference in SQ.

    +1 on the current requirement. My pair didnt wake up under 200w and high currant, the c's are the same. I believe the senistivity is about 86 db. They like lots of power, and reward you for supplying it!

    They are in the 90 to 92dB range.
