My solution has been to use two small cabs with 8" drivers. I pole mount a 1x8 above a 2x8; with the1x8 near ear level, I can hear my intonation clearly, while the floor-coupled 2x8 provides the beef. A variable high--pass filter, and thoughtful placement of my cabs relative to stage walls, enables me to tweak my sound to suit the venue. Best of all, the two cabs have a combined weight of only 30 pounds. Too bad Mike Arnopol is no longer making the Crazy8 and Crazy88 composite cabs; these are the best cabs in my arsenal.
Good luck!
That's interesting, are these all separate cabs? I'd love to see a pic of that arrangement and how they're mounted.
