remarkable project. in the 70's (and through to today) I played with a friend and any of his B12 B15 B18 trio was a treat. Usual thing was to run the output signal from the B-XX into a KUSTOM 200 head and into a pair of KUSTOM 2-15 cabs. I NEVER knew about the version with the double baffle till today. what hit me instantly is that it's the same idea as the Fender Tone Ring cabinet, but not infringing patents and not needing a special-stamped-metal part (said Tone Ring) . It's not so much a bass reflex (at ALL!) but a tuned port that opens into the front of the speaker driver: What you;re doing inside that sandwich is creating a volume of air that affects the low-end and cutoff frequencies. It likely has a bit better bass but the response just CLIFFS at some pitch (hopefull below the instruments lowest) Great thread!
