dB is a unit-less measure.

Its 10MW alright, but its unlikely that you'll start a house fire, 
other than perhaps your own, due to the current you'd have to source to 
run the PA.  ;-)   Your 4801 would evaporate in something close to a 
magnesium fire before that happened though, this would be accompanied 
by a very large "POP".
