Nearly all PA's run in mono to avoid phase issues, and because it makes the most efficient use of amps. You get the most power out of an amp by bridging it - combining the stereo channels of the amp into one output thus massively increasing the power.
not only that, but to make efective placement of cabinets to get workable stereo in your average club, it`s just too difficult.

The placement of the soundsystem is normally low on the list of priorities in all but the greatest of nightclubs.
Shame really.

But then, I¬m a Rig junkie anyway.
