Heh heh...good one, Rich. Agreed the 1500 sounds excessive but not at 21 feet away with M5s. If he went with M100s, his 4500 would be adequate.

The M5s need four times as much power as the M100s to develop the same sound pressure level. Also, the M100s can be used without a sub at those high pressures whereas the M5s need a sub or they start to sound like a Basset Hound in a dryer. smile
