Looking for a 1.4" 100-120° Constant Directivity Horn for a full range cardioid speaker

I'm looking for a constant directivity horn with 100-120° horizontal dispersion for a full range cardioid project. It shouldn't be wider than 460mm and ideally should fit on my 1.4" compression driver. The closest I've found so far is th RCF HF950, which has 90x50°.

At the moment the prototype consists of a 15" on the front, 2x 12" on the sides and a 60x40 horn I had laying around.
Does anybody know of something I could buy that would be a better fit to the low end directivity?

My printer is only 26 cm diameter (delta), but I printed this (cca 62 x 30 cm mouth and 42 cm length). It is 9 parts in total. The dark one is improved version, but still unfinished.
