The room is 15 x 22...and I do like it loud from time to time. Back last century, from '85 to '93 to be exact, I had a pair of cornwalls powered by a Luxman MX-100 amp (140 8 Ohm Watts). Sounded real nice but I was surprised how much power was being put out to reach lifelike levels. The meters would peak around 75W but maybe they were not too accurate. Even if the sactual speaker sensitivity was only 92dB, that would be 110dB with 64W input. It wasn't THAT loud!
