Can you share the current print settings? Wall thickness, top and bottom, infill, etc. Anything contributing to strength. Also, did you find an optimum angle to place the part to minimize the amount of material required for supports? I rotated the STL about 55 degrees from upright and it needs ~125 grams of filament for supports.
I've got a spare KABD 430 and I'm thinking of playing around with this design to build a speaker with that.
@Narcisse91 I use a wall thickness of 4 loops and 30% infill adaptive cubic with a .4mm nozzle. I'm sure a thicker nozzle would be better provided you are willing to do a bit of sanding. For the orientation, I use the glue face on the print bed. I found that greater rigidity was achieved by prioritizing wall thickness over infill. You shouldn't need and supports for the print. But, I some for the ports and entry just to be safe.
Let me know if you need anymore settings. The rest are pretty much default from bambu studio.

Thanks for that info, and the picture. Bambu was applying supports when I arranged it like that and I haven't had luck getting a smooth surface anywhere where there were supports, but if it has printed ok for you like that, I can manually block supports on it and give it a shot. The only real advantage I saw to printing it in a different orientation would be to enable ironing and try to get a smoother surface right off the printer, but now that I've got it the way you did, it is a lot less filament and ~6 hours shorter print.
Tweeters are out of stock, unfortunately, so I won't be able to build this any time soon, but might start gathering parts together and design an enclosure.

Thanks for the STL file. Here's a new clone from France. The enclosure is also printed with a Bambu Lab A1. Below is the bass speaker with eight 13 cm drivers.
For testing, I'm using a t.racks DSP 4x4 Mini Amp for the horn.
The subwoofer is filtered with a MiniDsp Shd and a separate amplifier.

Is the file included in post #22 latest iteration of the subject horn? Or has it been subsequently further modified?
Yes #22 is the current version. It’s a conical expansion with a wide round over. Future projects might use a different profile.
Thank you - apologies if its already been mentioned, but can please share whether you are using the 8ohm or the 4ohm version of the Dayton drivers?
