There's a fun sounding bass cab. Bit of a job in the 'pack and move dept... Sometimes you can buy great cabs (like a Peavey 1820) that are unloaded for cheap (bought my first one for $50.) Then hit up EV or whoever's speakers you like and load 'er up..
One nice thing about sets of tens' good one at least, is lots of cone surface per box size- and the high extension out of the same cab.
