Dmitry,
The outcome is great aesthetically! Great work!
How does it sound?

The sound is very large, all the images are huge and there is very high pressure. Sometimes I like to listen to music very loudly, The stage is huge and the effect appears as if it has expanded to the left and right of the speakers, I also noticed when you use wax on the horn and polish it, it becomes very smooth, this makes the sound more accurate, I also got a huge increase thanks to the fact that I removed the protective nets from the drivers as if a veil had passed And an even more accurate sound table, As for the Bass and transmission line, well, as you know, this design lowers the frequency resonance in my case, it dropped to 12 Hz, and the total quality factor also decreased to 0.17,can be described in two words This bass cabinet is just a machine gun

Ebony Maccasar?

I think yours look better than these (€17.000 per pair):

Oh, how did you guess it was him, yes, such acoustic systems. They are completely active. I am ready to sell them for 8,000 euros and I am sure that they play better than those that cost 17.

Hello my dear friend Docali, I continue experiments in acoustics

I also decided to sell my business and open a new one for wood processing, I really liked working with wood

Now I have my own workshop for the manufacture of acoustic systems, And now it's time to make a new project with your speaker DRBA Petf. I know you experiment a lot and know how to simulate, I haven’t come to this point yet, I would like to ask you to help me calculate a horn that would be, at your discretion, the best one that would play from 400 Hz, Thank you in advance

Best regards Dmitry

I will not have much time to help you, but I think the sheet has the splines export feature, and you could use the API script files to automatically import and loft the splines:

Then use gmsh to prepare your simulation mesh files.

I know how to use a calculator and I know how to create a 3D Model stl file but I don't know what param
ters will sound very good. I need parameters based on your experience which sound will be the best

Everything has been described here and the referenced first article:

Hello everyone, I continue to experiment with your projects and now I'm making these

Think of my system (attached below) with your spherical/ellipsoids rather than my tractrix and jmlc combo, it would be much shorter with drivers closer together. It would have also wider coverage... I would like to build even if it is just to hear the difference.

NICE woodwork!

this is my contribution to speakerporn😁…Jensen and some cardboard horns
DIY some time ago .. and trying to upgrade HORNS

 

[docali]

I would like to point attention to the first build of the mk3b2 described here in the forum:

And a very nice work based on my jmlc calculator:

And of course DonVK's WN270SE:
