Hi guys,
Hope your well, I wanted to share with you a horn that I have designed with the help of a spreadsheet, here’s some beauty shots.
I was hoping that in theory I used the spreadsheet correctly by using the graph tool in illustrator and creating a 2D projection of one half of the horn which can then be swept around the central axis. Further reinforcements can been seen throughout to brace the 2mm thick structure of the horn. According to the print it would weigh over 1KG.
Would anyone like the 3D file of it?
I have already had a quote to 3D print it and it’s pretty expensive but if you have the cash to spend then I’m sure it would be a nice horn to have.
That said if anyone has any input or would like to simulate the horn to see how it’s performing then that would be productive! I’m dreaming in 3D at the moment.
I’ve kinda been put off by the project for now and plan on maybe building a K-402 because of the preferred directivity and ease of build.
Thanks!

With a double set of 12s also horn loaded, 500hz up with this horn to make way for SPL. I’m just not a fan of beaming..
A 500Hz tractrix is usually crossed closer to 1,000Hz. Group delay becomes an issue closer to cutoff.

Impressive render. If your willing to use FIR processing and have some delay in the system you might be able to operate the horn closer to cutoff by using very steep filters and compensating for the group delay/phase issues. If you post the .step file I'm sure someone will simulate it. I would say me but I'm very tight on time so I can't promise. Simplifying the model to just the horn contour would make simulation easier. Or just follow this video yourself its not super difficult:
Sorry the 500hz unit is the crossover frequency, the actual tractrix is around 350hz in I beleive. I will have to pull up the spreadsheet.
