From the Polar Patterns, the -3, -6, -9 Coverage Isobars and 3-D Directivity Balloons it's obvious the Complex Conic Horn Technology is quite effective.

If you smooth out (loft) the edges, it shouldn't be too hard to clone and 3D print or CNC one of these. The pathlength, curvature between and location of transitions could be derived from the distances in the top- and sideviews (not shown).

I tend to prefer EAW products for this reason and moreover, because of the engineering contributions of this man:

In context of this thread, it's interesting to notice the impact of advances in horn modeling tools over the last few decades and which appears to have resulted in the return of the diffraction horn, or diffraction horn 2.0.

This EAW waveguide was developed some 20 years ago, looks familiar?

The same - EAW specific - B&C produced pancake drivers are used in combination with both horns. This is basically the same driver Roy Delgado used for (designing) the excellent K402 and K510 horns.
