    I know how some of the lower end Sonys and other brands say they power speakers @ 100w x 6 @ 8 ohm rms and higher at lower resistance. But realistically, its more like 35 watts per channel rms.

    I understand thats the way it is, but my question is this: How can they get away with advertising 100wpc? Wouldn't that be false advertising?

    False? Sure. Illegal? Probably not. It most likely it will put out 100 wpc but with so much distortion it's un-listenable. Some really cheap receivers will say "100 wpc @ 10% thd, 1khz into 8 ohms." Reality is more like 25 wpc @ 1% thd. Anything over 1% thd sounds bad. My H/K 520 is 75 wpc @

    Those numbers can be fudged one way or another, they can make them say anything they want really....

    In the end, most quality equipment, powers speakers just fine, and it is not so much of a factor in real world use.

    There are too many variables in power ratings. There is THD (total distortion), Frequency (A 1khz note is easier to play than others), # of channels (most only use 1 channel at a time), ohms, and time (anything can put out 100 watts for a fraction of a second).
