Don't worry about the math. I have tried to discuss this with an empty VBA sheet but it insisted to get programmed in the right way

There are three early tester out here and I think that the sheet is quite easy to use and has an iterative Flow.

Besides the article some fine tuning is still necessary.

so, are you stepping into "stereo lab" like horns for diy ?

Are they tractrix ?

Or spherical (more like avante garde) ?

Those 2 seem real close looking............

Any overlay drawing that can show the difference ?


Is "stereo lab" still selling horns ?

My horns are named as DrBA and have only the base formulas in common with SWH or tractrix but as true expansion tractrix. They will be free for private use. Besides this three completely new profiles will be presented.

And no, die nothing in common with stereo Labs!
