Hello,
i made a new construction
down to ~34 Hz
for 3", 5", 6,5" and 8"
bass driver,
15 cm flat behind the flat screen
or two with 100x120x15 cm,
or sideboard for
sat placement.

the 17 inside width
would be a best solution with the
TB W6-1916.

the 23 cm inside width
would be enough for
100 dB 1W1m up to
200 Hz with superb
sytem impedance,
by using a
8N MB420 16 Ohm 18sound
you can couple two
double horns (4Ohm)
with one Submodul.

opinions?

moreart I dont want to put down your work. I rather be help than giving you the wrong path.
I cant judge how good your box going to sound especially below 300 hz. there could be lots of parameters which may can accidentally(or on purpose) make a set up sound good or worse we may need to judge it by some critical measurements and our ears to hear it
btw how do you claim that this can be an efficient bass horn ?( we end up with big numbers making below 100hz horn beside the difficulties)
Im not saying it doesnt have some shape of horn but its more open battle that delivers inside cabinet standing waves(box sound) ... that may cant be bad it juz means that lots of works should be done in boxing it.
& I suggest if you  can switch the opening to tuned helmholtz resonator there you can get better results.
