I used to gig a Berg IP310. I cannot possibly imagine needing more. I often wondered about commissioning a build which put the speakers in a verical 3×10 + horn box with tiltback wheels - but the same internal volume. If I still owned it, I would have done it by now.
An Epiphany 3x10 rehoused in a box to suit you needs but with the same internal vol? They are lush cabs.
