If so, I agree. Those ports would be open or else no TL.
I've built two pair of TL woofer systems in my day, one pair of which I dug out of storage to use with my Beveridge 2SW speakers. Mine mimic the classic Bailey design as implemented by Irving M Fried. However, the shape of Duke's cabinet shown in the photo leaves open a question as to what goes where, but odds are that it's a TL, of some kind, IMO.
