You could refer to the “Maggie” cabinet dimensions on the WeberSVT site, it’s a Two Stroke clone. Or use the info in DH’s book. I’ve found that the Two Strokes sound great in a open back, pine cabinet.
If you want to buy a finished cab, I have a brand new, pro built cabinet similar to the red one I use for my user logo here on the TAN site for sale. It’s solid pine with a baltic birch baffle (cut for 1-12, but a 8/10 combo speaker layout will fit) with a D2H custom cover. It’s brand new, never had a speaker or chassis installed in it. It’s two-tone brown and white (vintage looking). Send me a private message if you’re interested.
