I'm in the planning phase of a 2 way MEH with the Celestion H1-9040 horn. I have the H1-9040 and it looks feasible to add either 1 or 2, 3-4 inch midrange drivers on the top or bottom of the horn.
This will be my second MEH so I'm familiar with Hornresp. What I'm not familiar with is the exponential horn. Horn flare at the beginning (1" CD driver opening) is slow to expand. This appears to allow the mid range opening at S2 to be less dependent on close location to the CD driver opening?
I only had a few hours to play with HR last night so I don't have any graphs to post.
Anyone else try messing with MEH plus exponential horn who can offer advice?

The short answer is not much. I have the Celestion H1-9040 horn, Peerless DFM-2535 CD, and settled on the Eminence Alpha 3-8 two per horn. It looks feasible to clamshell mount the Em Alpha 3-8s around the horn with a bit of shaping of plywood fillers. HR says I can get to almost 2 KHz with the Em Alpha.
My delay with the design has been I'd like to add a woofer for a 3-way design. I've got my MWAF entry for 2024 in front of this project.

Thanks for the update. Not sure the horn is big enough to squeeze woofers onto too but look forward to see what you come up with eventually. Good luck with your MWAF design.
I've just ordered a 9040p for the same purpose, hard to resist at £18 delivered.
Any advice or info gratefully received!
My only experience with meh is a modified conical ~60*40cm and 30-40cm deep with a 3fe22 at the throat. 6fe100s for midbass.
The 3" managed 3-400hz to I think 1800, sounded pretty good and LOUD. I had a crossover that corrected for the roll off to take it flat to as high as my hearing goes.
I'd like to try the faital's with a 1" CD to keep the >100db/w sensitivity and hand over to a 15".
Fun project.
