Hello,
I have a question about the Sabourin Speaker from Troy Crowe.
The horn consists of 3 stages. The 1st has an 15,5° angel and 47,2° on the sides.
Can anyone please explain why that is 47,2° and not 45°?
Fr.gr.

It comes from the exponential-spiral horn calculation. You can see the deviation of the three stages from the ideal profile in the article.
thanks,
but I can't see why this deviation,
cause 2×4× 47,2=377,6°
how could 4 corners possibly be more than 360 degrees?
oh, I feel so dumb🤣
