it was because chp50p is cheap versus maop 5 and have people who like it more.
with your conception waw does we have the same percetion 3d soundfield?

To be honest, it's probably going to depend as much on the listening room & speaker / listener positions as much as the speakers themselves. I don't tend to find good 2-way systems have major issues on this front though; for e.g., I still run my prototype Viotti Ones in my desktop system, in a fairly extreme nearfield setup and they excel as far as this goes, so I doubt you'd have any issues. YMMV as always though.
at a 2-3 m listening point do you think it is better to have a box with MA200+ MAOP5 or that it is better to have a MA200 alone in terms of dynamics and virtualization?

You can, but not recommended, unless the enclosure is within 4in of a solid front wall or loaded into a corner.
Noted about ports, makes sense 🙏
Also, this arrangement presents a nominal 4 ohm load given the two MA200 in parallel. Perhaps an 8 ohm version with just one MA200 like in this one, makes it easier to drive… performance compromise?🙂

Depends how you mean 'easier to drive'. Parallel wiring = +6dB sensitivity gain for a given voltage, with double the current draw of a single unit. Most solid-state and decent PP valve amps won't give two hoots, since by design it's not a very reactive load, and that's typically as important as the nominal impedance itself. Low power SET types may be less happy, although that too is often as much about the quality of their PSUs & output transformers as it is about their power output itself.
Also, the cross-over frequencies? I like the idea of externally connected filters, less interference and gives the option of active filters later on🙂
"Klirrfaktor" is troublesome on this one...

Designed for passive; you can't fully recreate it with active as it's also serving as some impedance control / damping.
A little old-fashioned -it's a configuration JBL used to use in the late '60s & '70s which I also quite like.
@Scottmoose: given that you worked on it, did you prefer a design where the MA200 is alone or for example your design where the MA200 is coupled to the maop 5?
No preference as such, because they're designed for different people / requirements.
Expanding on that a bit -sorry if it sounds odd, but it's just what happens with commercial design. Remember, I might design the enclosures / systems for the Markaudio site, but (and it's a big 'but') they
a/ Have to reflect some basic criteria / requirements Markaudio as a company have, and
b/ The relatively wide range of designs is there so it covers most bases, and inexperienced DIYers who have different requirements will hopefully find something that suits their preferences / needs.
Remember -these are not designed for me, and they aren't necessarily meant to be equivalents either: they're meant for a wide range of different builders who want different things. My own preferences are basically irrelevant, and they don't all reflect what I might happen to like or want to use myself. About the best advice I can offer on that front (which is a bit of an apples / oranges comparison) is: if you like single-driver systems, I'd be inclined to stick with that, unless you have plenty of cash and free time to try a few out. If you like multiways -same applies in reverse. That might be for acoustic reasons in either case -equally, it might simply be because you feel happier. I'd guess for most people, it's a bit of both.

I just noticed something here:
It seems like a first order crossover, yet the drived are wired with opposite polarities?
For the one with two MA200s there was a second-order crossover, with the drivers in opposite polarities, and that's ok.
The MTM is a 2nd order design -to be precise, it's an offset 2nd order Butterworth with some minor level adjustment & resistive damping, per some classic Altec & JBL designs. Not necessarily the current fashion, but suits what I was aiming to achieve with this design. The single MA200 box is a 1st order electrical with some impedance correction & level padding for both units, but the acoustical slopes are mildly asymmetric. Remember, there's no single electrical polarity that's automatically 'correct' in practice for a given [electrical] filter order -we're manipulating both electrical & acoustical slopes, so what it actually ends up being depends on the on-baffle driver responses & your target alignment.
@Scottmoose est ce indiscret de te demander combien couterais une conception d'un boitier du même genre avec un ma200 + un chn50p?
