-speaking of drivers for this design, here is the Test Bench of the Radian 745PB:
Test Bench: Radian Audio Engineering 745PB 1.4” Compression Driver | audioXpress
Other than the typical "hash" at the top of the pass-band, pretty good on a sub-par horn.
Still, I'd recommend the 18 Sound ND 1460 A or ND 1480 A .. and a good efficient ribbon around 6 kHz.
For the midbass section I'd pick the Faital Pro 12PR300 16 ohm x2 wired in parallel with a large volume bass-reflex and a much lower tuning freq. than typical.. (..sort of "sealed +") and a good filter for integration + baffle-step compensation.
