Thanks, I've managed to stay away from 3D stuff but perhaps it is time to step on the dark side 😀
Just verifying the functionality (noy yet prepared to be released) -
2" throat, 756 x 470 x 305 mm (60 mm adapter + 245 mm 2-profile horn), a raw horn in free air.

Can you also do WG/horn that are wide dispersion? If yes, did you ever present such a design here?

I would think so but don't recall anything I could point you to.

Given that this is without any mouth rollback, just a raw device hanging in the air, this is surprisingly good (at least to me) -

Looks similar to the profile of the 35x35 degree HF horn used in the three-way EAW KF750 from the 1990s:
They work well.

My concern would be the almost non-existent mouth edge treatment in the EAW HF horn (perhaps in order not to form too strong resonances in the chamber behind the horn?). I can try something similar later. (It may look similar on the photo but what I show is about 70x70, twice as wide coverage).

BTW, this is the first time I can easily design a horn with the possibility of different adapters for different exit sizes or exit angles of the drivers. The other geometries, where the whole profile is described as one piece of a continuous function, don't allow this. Regarding practicality, this wins hands down for the DIY folks who like to experiment.

Yes, there are already resonances and reflections from the mid driver phase plug exit diffracting around the HF driver, a lip on the HF could cause some long reflective paths.
This is a box that had good (very narrow) coverage consistency, but the resonance problems made it sound only so-so with the original processing.
After later implementation of "Gunness Focusing", FIR filters that took too much processing power to be commercially available turn of this century, the resonance problems were really brought under control, no more trading one honk for another 😉.

The EAW KF750 horns are not flat-sided, (conical), they have some degree of curve through the entire path.

Yea, I see that now, thanks for pointing that out, it wasn't very clear from the photos. I will try to get closer to that - I'm myself curious what difference can that make.
