Fair enough...which is why this project is not so serious and might not even
happen. I am just looking for opinions at this stage.

Are there any clues from a physical inspection that might indicate what I
can expect?

Well, you could build 3 boxes with a 3:1 range of sizes and see
which one sounds best.

At some point, measuring T/S parameters starts looking good.


Better than building 3 boxes, certainly.

I don't know about the UK, but in the states you can get a USB gizmo
with software that does full relevant set of driver tests using your
PC for under $100.


OK, but that would be somewhat more than I paid for the drivers. I do have
an amp module that goes down to DC as well as other bits of audio gear so I
might have a go at T/S parameters to give me a ballpark figure for the box
volume.

If I started this project would there be any benefit in placing two drivers
in one enclosure and on opposite sides? I know that KEF have done that in
the past.
