the 4.7uf 1mh was a first guess at 12db high pass, agreed the scale is badly done, done to get it all in. better version...
scrub those previous graphs, ive been dim, here is one without any passives between the 4p1l se amp and the tpl, much better!
looks good from 1.65khz, still the whopping 7-10db dip at 15.5khz
+-1.5db from 1.6-10.6khz
Looking good for crossing from the m5n12 faital at less than 2k
I was planning to cross actively between bass and mid then use a passive crossover to the tpl, but may make it three way active.

Can you please post pictures of the horn? BTW, if you attach the pictures as "attachments" I can see them from any device. The way you are posting now I can see them from my phone, but not from my work computer.
Can you describe your measurement approach? You seem to be using REW. What mic? Are you measuring in-room? At what distance from the mouth? What kind of gating are you using?
Have you measured the Thiele-Small parameters of your drivers?
I just purchased my M5N12 and waiting for them to arrive. It sounds like your horn is a lot like what I have in mind for this driver.
i tried again at a higher volume and more on axis which gave better results, apoligies for my ineptitude, seems depending how you measure you can get whatever result you want!
measured using minidsp umic-1, at 1M on axis, signal from E-mu 0204 into 4p1l SE amplifier, transcendar opt. horn is sat on 50 x 50 x 95 cm back loaded bass horn in a 4 x 8m furnished livingroom, carpets etc i'll try and get pics.
