advice for DIY Flush Mount Studio Monitor

Hi, near to build my new house im thinking about my room.
Will be a treated dedicated room where ill mix / arrange / record voice or instruments like guitar or bass.
I was thinking about to integrate monitors to wall, building a drywall structure filled with rockwool in order flush mount speakers.
This idea was born since i was thinking about distances and stands in order to keep my nearfield far from backwall and relative absorbers and table placement ( i cannot put desk in the middle of the room ).
I was planning to build a 3 way speakers with:

1 SB SB29RDNC-C000-4 ( from 2khz )
1 Faital 6FE125 ( sealed, 200hz to 2khz )
1 Dayton RS2258 8" ( front reflex, to 200hz )

I was thinking to put woofer and mid aligned horiz and tw centered in the upside.
Passive crossover will be calculate.
Placed angled at 2 meters from eachother and listening point centered at 2 meters from each speakers.
Any advice or suggestion about ? Thank you
 
I'd recommend orientating the drivers vertically if possible.

Our hearing system is very good at distinguishing the location of sound sources left-to-right, and I find it's pretty easy to tell which drivers are where in horizontally-arranged speakers when used at a relatively close listening distance.


I'd also recommend a smaller midrange unit, and/or a waveguide for the tweeter, to ensure the horizontal dispersion pattern stays smooth through the crossover range.

Ok so:
At the crossover point of about 1,8 / 2 khz tw is pretty wide, midrange have about 5db at 45°.
Watching 6FE125 response seem pretty wide under 1,7 khz, upper seem... not so good expecially with a strange off axis hole at 3,8 3,9 khz.
Tweeter seem to be narrow in the upper part from 12 13 khz.
Commercial monitors generally use soft dome small midrange but i like a lot the ideas to give a lot of works to a single big midrange and watching some datasheet about this kind of Midranges situation seem to be better in the higher cross point ( MDM 55 - Morel 2.1" Soft Dome Hybrid Midrange start to have -5 db at 4khz 45° ) but worst in the lower... should be crossed higher where this woofer isnt soo good.
Ahhhh the blanket is always short!😵
How serious is the situation? is it acceptable with some tricks (like Active steep crossover 18 / 24 db, waveguide to keep narrow the tweeter, vertical displacement like MWT) considering they are studio monitors with a big big front baffle ( flush mount )?
How generally an elliptical waveguide affect dispersion of a tw?
Thank you
