You more or less answered yiur own question in post 21: that is the real deal.
The first striking aspect of the #21 design is th wide overlap of the drivers output between 600 Hz and 1.5 kHz. Most likely this will lead to erratic off axis behaviour of the system.
My recommendation would be to use fourth order acoustic (not electric!!) slopes for both drivers. Next thing is move to Vituixcad instead of XSim: quite a step up in capabilities , and with a steep learning curve, but absolutely necessary if you want to move away from the "single-point-on-axis-only" design approach.

Thank you!
A question that has been bothering me for a long time.
Where to take the recording of the speaker, a meter from the speaker or from a listening position?
After all, when I perform analysis and correction of crossover parts, I do it by listening position and not by a measurement 1 meter from the speaker.

The usual "design point" distance is 1 meter from the baffle. Look e.g. for "Measuring Loudspeakers" by Joe DÁppolito, or the various ARTA Tutorials.
Could you post the .frd and .zma files of your drivers?

The problem is not in measuring the speaker from a distance of a meter. The problem is that after the measurement and design of the crossover, The measurement is done at the listening position, then correction of the crossover, then measurement, And so on.
Anyway, I play a lot with Trial and error, and enjoy 🙂
