Diki, down here nearly all the venues are outdoors, consequently, the drop-off seems to be more noticeable. And, yes, Donny, there is a drop-off with ALL sound systems, but it is far less with the Bose vertical arrays, averaging less than 10 percent at 50 feet with the L1 Compact. With the standard L1 and Model II, if I recall, the drop-off was about 10 percent at 100 feet, which is negligible in comparison to conventional sound systems.
Good luck on whatever you decide upon,
Gary
