I've just been given a pair of '80s ADS L1590/2 towers. They sound awsome behind my Yamaha M65 Power amp at 170 watts RMS/channel. I'd like to use them as the mains in my Home Theater which is powered by an Onkyo TS DS595 which puts out a clean 75 watts RMS/channel. These speakers have dual 10" woofers and are probably pretty hungry, though. Are they too much speaker for my Onkyo? Thanks for any help.
