I bought the cabinet from Mojotone. It's their Tweed Super cabinet, which happens to fit the 17" x 4" x 3" Hammond chassis perfectly. The stock cabinet is cut out for 2 x 10" speakers, and that's what I'm using currently. For a small extra charge, Mojotone sold me an extra baffle cut out for a 1 x 12" speaker. I bought it just in case I decide later that I'd rather have a 12" speaker.
