Bandsei,
Thank you for posting your project here.
I have been using an Oskar Heil Syrinx for nearing 10 years now.
And lately, I have been experimenting with BG neo drivers on full open baffle projects.
I have already made a dipole waveguide for a neo3, very similar to yours in design and materials.
My next project is a similar WG for a neo8s (drivers in the post).
Your DIY AMT has similar height to a neo8? What is your view on your driver's vertical dispersion and effects on listening experience?
I am hoping to be able to use the neo8s without any tweeter or supertweeter on top.
To increase the vertical dispersion, I will experiment with felt and foam covering 1/3 upper and 1/3 lower parts of the radiating surface of neo8. Just like Raal does with their taller ribbons.
You seem to have much better skill, knowledge and equipment to test this idea.
Would you give it a go?

Sorry for my late answer.
My AMT´s are 170x40mm,active app.150x32mm.
Vertical dispersion is like line source,not good.I plan to make another model with the AMT´s horisontal.
A shorter diaphragm acts maybe more like a point source.
I will be eksperimenting with vertical dispertion.

Have you considered just exposing less of the diaphragm to a horn?

It might be good to have the glued ends where displacement cannot be as linear removed from the output. Maybe you'll still have enough output.

It might work,like a shorter AMTwould.
But i like my own idea,and have not seen this idea used.Could be fun.
I have made someting similar:

This one is with 5 ribbon and vertical.
The new idea is horisontal with 3 AMT´s.

I use hard wood and normal glue for wood.
