Dear all,
thank you very much for linking my homepage. Unfortunately, my French skill dates back to early school and therefore I will answer in English. It is an honour to be here.
My interest regarding horns awaked when I attended the HE fair in Munich where Silbatone presented their WE12a/WE13a combo. Still the top of the food chain ;-)
My first waveguide in my Wolf von Langa speakers was replaced by a Tractrix horn. This was a step in the right direction but I got sometimes nerved by the slightly beamy behaviour. At this time I planned to extend my Excel VBA skills and begun to play around with my very first horn calculators.
As my source code is quite flexible to use different horn functions someday there was the challenge to deal with JMLC horns and add my features like stretching or stereographic projection. i these days where in many forums directivity is everything and loading unimportant I do not agree and think that a proper horn need to have an excellent loading characteristic. One way to get better directivity is my PETF method.
All the rest can be read on my homepage

A few days ago i changed the page theme and the photos were made on Helgoland.
When i have some spare time I will continue to write new articles as there are some other work that is still ready.
best regards!
Bernd
