I use 2 C4's with a GB shuttle 6.0 plenty of power and sound, coupled with a Whirlwind bass graphic EQ, although haven't used it anywhere where I could crank it up. The C4 is still a reasonably heavy cab for the size, but after owning an Eden 4x10 cab ceramic magnets, the C4 is a featherweight. Yes you'd need 2 C4's if you're going to stack it against the Bergs, not that I've heard them, but good 12's against good 5's with bass low end, you wouldn't want to compare doing open air concerts, particularly if you're using 5 or 6 string bass! If you're wealthy enough, have both.
