Fran, you know that's simply not true.
Most will not enjoy the stereo experience.

If you're playing EXTREMELY small venues, then there would be a better chance that more than a select few could get some sense of panning/stereo imaging.

We often play larger clubs that have seating (and in some cases) dance floors that are unusually placed i.e. off to the side, widely spaced, non symmetrical etc, and the chances of any kind of pleasing stereo effect being conveyed to anyone not in the "zone" are nil.

(Ironically, the topic of this thread is Best/good subwoofer, and whilst I don't think it's veered too far OT - this is a worthy discussion - subwoofer bass frequencies are, of course, largely non-directional! lol)
