So do your horns have 115Hz flare frequency? (and have the rear chamber tuned for 115Hz as well)
From the pictures the horns look like that they are made from MDF. Is this correct?
I fully agree that the midbass is the most important (and also the most difficult to get right). I am thinking about starting with your Fane Studio 8M. I like to build on what others did. Could you, please, tell what midbass drivers did you try and which did not work as well as Studio 8M? It would be very educational. Purely on gut feeling, I would like to try Supravox 285 in field coil version. The problem with fieldcoil in a closed chamber is the heat generated. The advantage of a fieldcoil driver is that one can tune the driver by varying the fieldcoil voltage. It is much more money than Studio 8M and I would likely repeat your search process. So I better stick with Studio 8M.
What is the impedance of Studio 8M? Its RE=6.2Ohms so I guess it is an 8Ohm driver. Interestingly, I found somebody with 16Ohm Studio 8M. And what is the sensitivity? I have seen as different numbers as 91dB and 101dB.
Your current system without a tweeter is in some respects similar to JM LeCleac'h's system: he also now runs mostly without a tweeter with TAD2001 on a 380Hz horn. He adds a tweeter only when more people come to get a wider sweet spot.
