Unequivable,hogwash. This is one of the magor strongpoints.I use mine with a 20 piece band and I have to watch it and not try to compensate as before. The drop off at 15 feet is 10-15%,then even for the 150 feet I need to reach.

The beauty of it is you don't blast the people near you to reach everyone else.
