there should be several sizes doable with the smallest being the original 1954 Karlson Eight which is only 1.1 cubic foot in external bulk. I tried to do a video but my camera's audio overloaded so I dug out a Zoom H2 and took audio of the little speaker playing. YouTube - 1954 Karlson 8 coupler with Tangband 1772 - sound on H2
I've gotta pay for a FE206EN and another builder has given some ideas on a coupler for it with starting point 20"Hx13.5"Wx12"D (maximum depth to allow blocking off some of the rear volume.
1772 plays well in the old K8 or 8K - the lower of the 3 slit vents might be blocked with tape. A 6" fullrange might play well. Whatever driver is used needs good treble extension and power.
