Default DrBA horns at sphericalhorns.net

Hello!

Everything started with this work here:
Klangfilm spherical wave horn calculator - from round to elliptical

Now, after a long time of research and programming I would like to introduce my new website:
Sphericalhorns – This is an exclusively private blog about spherical horns without any commercial interest.

The first two theoretical "papers" have been published and the next is in the making for the Kugelwellenhorn. This would be also the time when I will provide my spread sheet calculator to the community.

Have fun!
docali

Just dropping in to say I enjoyed the read and the many examples on the other thread. Interesting work, can't wait to see some of these horns come to life.

Hi!

Thanks for your feedback! You are welcome!

Is is quite cumbersome and time consuming to write all these formulas and prepare the pictures for a web page but it is necessary as most things are pure math.

The good thing is that first BEM simulation with help out of this forum here showed very promising results and therefore I hope that some day one of these horns come really to life.

Greets!

Thanks for sharing! Now all I've got to do is make time to read/'absorb' it, though will have to skip over any higher math, so hope it's 'dumbed down' enough to understand at least the basics.

Thanks for sharing the insight and the math behind the elliptic horn designs. There is a lot there to digest. Looking forward to more posts.

It will be interesting to see one built. At 400Hz fc those will be big horns.

Docali has produced a masterpiece.

His understanding of math is at least 10 levels above mine, probably more.

Great blog! I will be following. Thanks for sharing the knowledge.

I have a 5 way round horn system, I love them but also I am hearing the same things with you that can be improved upon. When you share the spreadsheets I will try and build one.

Wow, you really are serious. It will be awhile before I can say something. Until then, just keep going - you gotta audience here.
