At typical comfortably loud listening levels(such as your -20)the speakers are using about 1 or 2 watts. Extreme peaks in the music might draw 50 or 100 watts(at the same -20 setting)for a few thousandths of a second.
Which is where we start getting into RMS (Root Mean Square) versus PMPO (Potential Maximum Power Output) or subtitled
Why these 200 watt (PMPO), $10 computer speakers sound crappy compared to a pair of 8 watt (RMS) Klipsch speakers".
Ooh, I got a compliment from Alan, whose articles I've read since this goatee was a lot thinner and darker than it is now.
