Steve,
Could you find the Internal volume of the box In litres and the Internal diameter and length of the ports? Assuming Franks link Is correct for your woofer, the first thing to do Is to reverse engineer the speakers port tuning and low frequency extension.
A very accurate way to find the port tuning frequency Is to lay the speaker down and put something like coffee beans on the cone. Play low frequency test tones through the speaker until the beans stop moving. When they stop moving, that's the port tuning frequency and that's the point where maximum air velocity will be moving through the ports.
Hi. I am sure the volume of the cabinet will be on the spec sheet but maybe not the ports, although to be honest they look more like just holes in the baffle. I am pondering options while I wait to see if Tannoy get back to me with the driver model. I am envisaging a 3 way with either a front mounted 12" or 15" side mounted woofer...🤪
However this is all academic if the drivers I have are not any good, and besides I would have zero knowledge of how to design a box and even less so how to sort out some kind of crossover for a woofer, assuming I use the existing one which looks like it was built by the military for the vx12 driver.
