When my band bought a new Yorkville LS720P, I stuck my AER amp on top to check it out. Wow! It was fun making that much low end.
I can't see ever using such a setup, though. In a small club with no PA support, I just wouldn't need that much, and there's no sound man on earth who'd want to deal with it on stage, and I couldn't blame them.
