I'd buy 2 used Ampeg SVT 410HE's and stack 'em. You can get them inexpensively. Modular fridge, probably leave you with $400 left over for the bar. Source: I use this rig and it's fantastic.
I use this cab setup myself, with either an SVT-CL (2001 USA), or more recently, a GK 1001RB-II. Here's mine -
Had an Ampeg 810E (circa '91) that went toast in early '99 (club fire, it happens!), and these 410HEN cabs replaced it, one at a time. There is a lot of weight in this pic, but the sound is incredible. Not to mention, the speaker height is greater, about 6-8" over an 810 (with casters), IIRC. If you can handle hauling this rig around, I highly recommend it.
