[QUOTE="Rob Timmerman, post: 217094, member: 172"] Nope. Loss at a given distance is a function of the source size relative to the wavelength. Pat Brown et al do a good job of showing this for linear sources at [URL]https://www.prosoundtraining.com/2010/03/17/line-array-limitations/[/URL] but the same physics applies for area sources as well High-Q speaker systems seem to push sound into a room better than low-Q systems because they excite the reverberant field less and increase the direct to reverberant ratio. And in a reverberant space, if you look only at what your SPL meter reads, a low-Q system will usually put more energy at the back of the room due to lack of falloff past the (shorter) critical distance.
