Add.: comparing the measurements in line chart form, the data from the Somasonus website doesn't quite match with what I've measured.
Comparison horizontal directivity for the 6,5" elliptical version w/ PS, SB26ADC-C000-4; scales, SPL and overylay colors matched; left Somasonus, right myself:
The Somasonus measurements show a broader beamwidth at the lower, and a narrower beamwidth at the top end of the frequency spectrum.
My measurements were done in free air, on stand / platform, 1m height, 1m distance DUT <-> mic, 2 ms gate, Class 1 FR mic with frequency & SPL calibration, graph 1/6 oct smoothed. Can you, @augerpro , name your measurement methodics, environment, variables, so we can diagnose the source of the differences?

I think I did revisit the circular SB26 in 5". I don't remember how it looked. I'll take a look again but it won't be anytime soon. I'm finishing my last classes for a degree and there may be a serious health issue in the family that may take me away from doing anything for awhile.
Hi guys, do you have any sugestion for 3d printing service? what material will work best? i have an access to shop bot cnc router. is it posible to cut a vaweguide directly into the mdf baffle? i have only basic knowledge in cad design, enough to make and cut speaker boxes on shop bot.
but you are doing amazing work!

Bogda89,
I did one my ones is MJF using the Craftcloud website - they will get you offers from multiple 3D printing services, and you can choose.

All the best and good luck!I'll be graduating in a couple weeks
