I would vote "no" on the Bassman cabinet because it is NO way as deep as the 2000S cabinet and won't give you the bass response you need. If anything I would opt for a 200S cab, they are pretty common, and reasonably priced. Even if you couldn't get one with JBL's, you could always put them in later. I have to look at a friend's house, he has 2 Sunn 2000S heads, and 2 Sunn Coliseum Bass heads in his basement, and says he doesn't want them so I should come by and pick them up before they get given away to someone else. I will look and see if he has any cabinets, if he does I will keep you posted.
