Thanks for sharing!!!
I have started to print it out and was wondering a few things..
1. how did you attach the woofers? Did you glue a m5 threaded rod in the holes? heat set inserts?
2. I am using a DE250 and sould like to modify a few things, are you happy to share a step file?
Cheers, and once again thanks for sharing. 🙂

There is a few different things I would like to play with.
1. The de250 has a slightly different exit angle
2. Compression ratio for the mid
3. I have some ideas with phase plug / multicell on the mid.
As for 3 I was wondering why some of your experimentation with this didn't make it into the horn. I am guessing time / different project to work on?

The exit angle might be a bit awkward to change. I generated the horn profile using ATH. You might be able to regenerate that with a different exit angle, loft it all and cut it out/fill it in?
The split phase plug was for different issues I was having when using more than two drivers on a horn. With two drivers it's easy to get the acoustic center of the taps towards the middle to prevent cancellations. I also think with one compression driver you only really need two of these 4" drivers for it to be balanced and not distorting the top octaves of the compression driver.
If I have time on Monday I might share the step file. I won't have chance before then.
I have updated the printables with details on the inserts I used

Someone PM'd me for this detail but I thought I would share it here. If anyone is wanting to make the same sort of front chamber as me on their MEH This is what I did:
Extrude the central 102.206 circle back 2.5mm
Then this is the side profile for the cone
This seemed to work well and provided enough front chamber but I would recommend printing a test piece to make sure it fits and you aren't going to hit the cone.
