Just out of curiousity, I tried this out yesterday at Carvin (I was in the neighborhood): http://www.carvin.com/products/single.php?ItemNumber=112AG&CID=GA Amazingly, it put out quite a bit of sound for such a small box (although I probably wouldn't put my 1200 watt Ultra through it....). I haven't been a big fan of Carvin bass gear over the years, but this thing seems pretty cool. It's actually the extension cab for their portable PA/AG amp. At 26 pounds, it's a feather-weight. Anybody else ever try one out?
