    IIRC they're rated for as little as 10 wpc, all the way up to 500. Though you can get sound out of them with the lower number, they don't wake until you get past 100, in my case way past.

    I think it's in the 90db to 92db range, and I'm pretty sure it's 92db.

    No... It's lower than that... According to the old Stereo Review magazine, the RTA-12 was tested at 87dB@ one meter/2.83 volts or one watt. I think the specs was about there as well...

    As much power as they need to have to really open up I would feel it has to in the low to mid 80's. I cant find it noted anywhere.
