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".
