Ahhh, that's better.  Isn't that just, y'know, comfortable?

Who's he talking about?  :-)

And extending it out to a triamp system:
  Low amp: 100 watts
  Mid amp:  50 watts
  High amp: 25 watts

Total: 175 watts

But the full range amp necessary for the peaks is:
   (sqrt(100) + sqrt(50) + sqrt(25))^2 => 487 watts
