Again thanks for your effort and sharing those measurements, jzagaja.
till ~4kHz plot is as I would have expected (more or less) but past that, there seems to be something strange going on.
Its been reflected in the LeCleach contour as well - just much less pronounced - maybe due to the extended tolerance regarding driver / horn matching for JMLC contour due to the lower flare rate at throat compared to Gaussian MinPhase?
Any chance you could do for both horns with just another driver some day?
Possibly a special adapter to a smaller than 2" driver would work better...
Let me know in case you intend to tweak.

This comparison definitely looks interesting - though I'm not exactly sure what conclusions to draw from those measurements....
Could you provide an overlay of all three contours where dimensions also can be estimated ?

Faital have a new 2" listed, and probably cheaper
Yes, I would also expect some drawback when pushing a driver below what is common
Faital specs 900hz as minimum xo requency
That ofcourse is also related to powerhandling etc
2" drivers seems mostly about higher SPL, and less about low frequency or quality
And ofcourse there are drawbacks at high frequency
Thats how it always is, nothing new there

Actually we need redesigned compression driver with removable phase plugs. Should look like Faital Pro HF10TX. With rapid prototyping for such a small part like phase plug it is easy and cheap. In STX as one part you have a magnet, phase plug that can be removed, conical duct and pole pieces. OS curve could be turned somehow in a conical duct but I still prefer completely new design. Minimum quantity in Taiwan 100 pcs.
This one ?

What is "Ketone Polymer" as a diaphragm material ???

Those of my friends who used Minphase as tweeter were very satisfied. In 2020 it would be interesting compare 12-15" waveguide with Minphase. Michael are you here? I can scale down Minphase 200.
Hi
Why not just give it a try?
Will definitely be interested to see real world results.
Hi Michael, nice to see you again after 10 years. From my side I can offer large 3D print. My friend can lend me DE360 driver.
I would love to see some CSD and wavelets from this. MinPhase 200. As I am preparing some class material and looking at past measurements, this is looking interesting. Starting to look at different options.
Here you are - change Minphase 4590_z01.zip to Minphase 4590.z01
I'm working on large printer and soon be able serve print horns up to 2 meter large.
