yeah but most people that bought the pg rsd's and swore they took 150rms+ a piece and sounded great, usually a week or two later complained about tweeters being blown.RMS ratings don't mean everything. Some speakers can safely handle WAY more than their recommended wattage...
im sure there are sets that handle more than their rms safely but you are usually talking mid to high dollar sets that can do that, in most cases budget comps should be kept near their ratings.
