Thanx for the llast pick, confirms Allen got it right.
Now someone might be able to do some XO modeling, even with the skint driver data?

It looks like the "diffraction filter". I agree it's somewhat 'unique' 😉
If the answer to this is yes, I think it will be the way forward.
Say, you could measure the whole speaker like you did, then the W and M with the T disconnected, and then the T with the W and M disconnected... and you did them all without moving the mic, and you let the plots overlay each other on the graph.
Ah, OK. That should be possible. Might be a project for this weekend.
I have made an illustration of the Mid/Tweeter crossover.

Ok. I hope this is what your after.
Frequency sweeps of each driver in their crossover
Audacity project folder (please download as a zip, lots of little files)

Room EQ Wizard "REW" (wonderful and free) would be the most logical tool for over-layed sweeps. Load resistors across all unused drivers a good idea.
Subjectively, the first thing I would try is to jump (short with clip lead) the 1.8mH coil/R combo and listen -does it get worse? better? - or just "different"?
Also, reverse the tweeter polarity and compare.
