Actually I counted the pleats and it appears to be 2 15's with horn cabinet and the horn removed and the baffle cut and flipped and bottom of the cabinet shortened.
Your right Pleat....I miss counted. Thought it was 10 not 15. No wonder I have to redo my W-4 again. Too many late nights working on my taxes.
Seems to me since I don't see any wheels on the cabinet, that it would make more sense to flip the baffle board and turn the cabinet upside down......I'm assuming the T&R is also rippled on the bottom as well. At least then the handles would be at a practical height. With an amp sitting on top, you'd not see the seam.
