You should also note that with the start of the K250 heads in 1971 the 2-15" cabinets when from being tapered top to bottom like for the K200 models, to straight face, as in no taper.
This added internal cabinet volume helped out for Bass guitar usage on the low E string.
Also to be noted in that even with this internal volume increase the cabinet needs more port area for Bass than the two round ports provide.
In this light if you do go foward and build a cabinet I would add a 2" slot port on the bottom of the baffle.
The port width should end 1 1/2" from each side of the baffle board.
The overall cabinet should be 2" taller to get this right.
