I'm not trying to start anything, I'm really curious. I can't imagine when you'd need all that power. Don't you ever use a PA?
My Shuttlemax 9.2 through a pair of fEARful cabs (which use high xmax pro PA subwoofers) often produces much cleaner bass in the room than the PA can... Depending on the PA, subs, and who's behind the board.
Anecdotal example: At the last loud outdoor gig I did with full PA support, the sound guy ended up leaving me out of the mains because he said I sounded so much better from the stage... and he's a bass player whose day job is live sound.
