As far as I know is there no official Diezel-Cab available. They tought about, but as there are enough projects remaining I can't imagine that there will be anything soon. I made my 1*15" out of a used 2*12" rearloaded Diezel-Cab, changed the front board, added 2 holes a 100mm and put a Celestion 15K100 Spider into it. It's for me not a stand alone solution but fits well with the 2*12" and even the new 4*12" rearloaded...
