I played one of the Ampeg V4-B cabinets, interesting tone, but you couldn't hear it very well, standing next to it, but 20 or so feet in front, it would liquidize internal organs, the throw of those cabinets is pretty amazing, for an outside gig, maybe yes, small/medium bar/club, hell no, gotta have a pick-up truck or Suburban, to haul one around, there are a few, still around, if your willing to wait, in your search, to build one, you'll need some good cabinetry skills, to build the horn section
