I would like to add a couple more things.
First (a minor quibble), it the horn profile you are showing appears more like a 3 section approximation of an exponential horn (consisting of 3 conical sections).
Exactly.

BTW, what are your horn dimensions?
This just my first shot to get the hands dirty. Horn model is based on John Inlow's 135Hz horn (
https://inlowsound.weebly.com/135-hz-mid-bass-horn.html ). He built it like a tank, I am trying to simplify it. Length is about 34" and mouth is about 17".
The frequency range of this horn does not meet my requirements for an all-horn system. I need to hi-pass the 500Hz CD at about 1kHz which means the midbass/midrange horn should to goes up to 2kHz. The plan is to split the 100Hz to 2kHz range into 2 horns, something like 80Hz-400Hz and 200Hz-2kHz.
Playing around with hornresp. It does a good job of modeling single section expo horn but the multisection horn modeling is essentially a trial and error method.
