Give me time to figure out. Previously I used M-audio Transit with Bruel Kjaer 2610/4149.
That looks lovely, Jack.
Personally, if intended as a free-standing horn, I would make it round, I couldn't keep looking at this all the time 🙂 I believe it would not get significantly worse.
Diffraction horns has better driver loading And same directivity. And also better phase response.
Sorry guys, I've just realized that I'm already using a newer version of the tool, so you will get a different horn for the input parameters presented here for A9 😱
To get what I get, use the the newer file:

Extruder motor does not work and it appears to be motherboard failure. This will slow down rollback print.
When running the ATH4 tool, I get the error "the application was unable to start correctly (0xc000007b)" I think its some dependency that could be missing. I'm running on windows 10-64bit. should it work on this version of windows?
Thanks MBAT, turns out if you are running 64bit windows you need the 64 bit gmsh dll
Estimate it piecewise from the coordinates of the points. Or print it as large as you can and use a compass and a straightedge.
For the terminated waveguide formula, it could be calculated directly by integrating: Arc length - Wikipedia - I won't do that 🙂

May I be so blunt to ask if there are some designs available which have been designed with this software?
I have no knowledge of maths and/or designing WG's. I'm just a simple guy which wants to makes his first speaker. I'm looking for a WG for a 1"dome that can be crossed to a 6"woofer at 1,6-2khz.
I understand this comment is pretty ignorant by dismissing all the shared knowledge and aiming for the chery directly.

You see, after slight altering of some of the parameters, the two would almost match. The "only" thing different would be the throat.
The tool is out there... That's all I can say, I don't do any "designs available". I wonder myself why there are not many more designs to see already. Maybe there are, but people just don't want to show or share them, I don't know.
My "Metlako" speakers, version one and two, were made with this software.
Link is here : Metlako: A Small, Affordable Two-Way Unity Waveguide
In the pic above, the big wood speaker is Bill Waslo's "CoSyne" speaker, the black speaker on the left is Metlako V2, the orange on the right is Metlako V1, and the one in the center is my "unitized image control waveguide"
Just one guy's experience, it is a huge help, and there are also still steps along the way that are out of your hands.
- I ran into some difficulties following Patrick Bateman's advice on using Meshmixer to translate the surface generated by ATH4 into a solid.
- Worked past that, then ran into issues with my 3D printer jamming now that it's been upgraded to use a fat nozzle. More debug and testing to do on that (slow - can take many hours into a print before it happens).
- Also running into uncertainties about concrete design parameters - how thick to make it, how best to chop up a 15 inch horn for a Geddes-like design into multiple pieces to enable printing.
I wonder if these are similar to issues other people are running into. Not complaining, this is cool stuff and further than I would have gotten into it. Just sharing that there are still challenges.
I just ran the prog for the first time and of course its looking for gmesh dll so I downloaded the one from the link but it is now version 4.4 and it doesn't work, I tried changing the name to 3.4 and that doesn't work either, can any source the 3.4 dll?
fyi, i've noticed there is newish web technology called WebAssembly. Mabat, could your tool compile to webassembly and run on browser?🙂 carry on
