I can't find any pictures, but back in 77 when i got my basses from Alembic, I also got a small mountain of Hard Trucker cabinets (from Wizard there. no idea what his real name was - somewhere i still have his card, which says Wizard.) - my full bass rig was 2 of the big 15 and 2 of the 2x12 cabinets on each side of the stage, with bgw, crown, and some other amp the name of which eludes me powering the Gauss drivers. Amazingly inefficient sealed acoustic suspension cabs, and the biggest sound I've ever heard. Even played at a low volume, it moved a ton of air. Also didn't make friends with the rest of the band, since we all pitched in on loading and unloading. You can imagine how the guitarist, who played through a Vibrolux, felt helping me move all my crap. I really miss that sound, though.
