Half-size Orelo VS traditional midbass horn (Orelo/Orelino)

The front would require a typical horn driver with low qts, while the OB back would require a very high qts above 0.5 to work efficiently...

If you're thinking passive then yes... with an active system it does not matter much, just give the lower frequencies more gain.

With that in mind it will be better to have the strong motor again with the low Mms for a bass with more "punch" and own control instead of flapping wooferen without any control due to their releative weak magnet.

BUT I guess the waveguide nature of this design doesn't actually work as an impedance transformer with a fixed air volume in front of the driver cone, thus no requirement for a very strong motor.

It still does but the "boost" will be in a narrow range which is still good because that boost will be in the crossover range to meet up with the horn on top.

It would be an interesting process to build something like this in iterations, first test it as a waveguide and then see what happens when it turns into a horn!

Sure! but closing-in things more makes things resonate more and will add more colouration to the sound.

For real deep bass you'll need a real horn (length, size and surface!).
