Chances are, the reason the sound is more raw at a dance club/rock bar is that stage cabinets are made for power handling and to be bulletproof, this is Cerwin Vega's bread and butter, you can run mains power to them and they'll hum along at 60Hz, but the tonality isn't there. Not a personal shot against C-V, but they're probably about the furthest on the fringe of this (dirty job, but someone's got to do it!)
Also take a look, some of that distortion is probably vomit, spilled beer, blown horns and discarded raver glo-sticks.
