Lets say I want to build my own 3-way horn loaded Hifi System. Is there any literature how to design the horns? lets say if I would have some nice 3d-drawings of one already existing 3-way horn loaded system how do I identyfy to design the phase plugs and the oiriface? How can I identify the distance in-between the oiriface and the speaker. I am looking to build something like famous Air motion ( Void) or the Orgon (martion)
 
Tequilahut, unfortunately I cannot refer you to any literature how to build horn loaded Hifi System. It just does not exists. Well, there are some more or less good books or articles about horns but none of them convert methodological practice to convert you listening objectives into a concrete horn-loaded loudspeaker. Some of the web sites, including mine, and manufacturing houses who offer some guidance but in a large degree the recommendations, practices and priorities are very different and you would need to have a lot of own experience to be able to distinct the noise to anything that is practical for you. It is not to mention that all people have attitude and to a great degree it clouds this best intentions. This is very much applicable to me. I for instance a “violent” supported of time-alignment for individual channels and this is why I look in the direction of the Air Motion design with a disgust.  You might find some groups online that patronize Air Motion or Orgon and they will be happy to give you some tips. Generally what we all do is adopting all imaginable ideas out there, apply them, observe the result and then navigate ourselves wherever it goes. With development of own acquired taste we compose our own know-how. My experience with the field suggest that unless you discovered the things yourself you do not truly understand it. It least it is how it works for me. I am a very good carpenter for instance and everything I did worked well…. after second or third attempt....

thank you! Roomy Cat
ok thats bad. I ve got a Mechincal Engeneering background and I am pretty good in simulations  - not saying that these things are easy but possible (cosmos/ansys and co.) you name it. 
I like the sound of the Air-Motion a lot as long you stay in the Techno gerne... And thats basically the only music that I listen to. However I just love the look of a horn loaded System like that - that will probably sound to you very stupid because look has nothing to do with sound.  To be honest with you I am really with you and think I will need to have multiply attempts since I have something that works and sounds "great" or "great enough" in terms of self-made/diy speaker - if that makes any sense to you. What I fear a lot is building something without having the correct background and starting at zero. My approach would be - like I know it from my job: Calculate, simulate - put that into cad If possible built a trail/test unit, evaluate and recycle that procedure or build the End-product if its already good or good enough.
Let me point the following out: I found a year ago some used Air motions for about 20k Euro. That is a lot of money for speakers. When I do have to build 3-4 different attempts since I have something that works I could be better off just buying them directly from void or any other vendor that does have something like that in their portfolio (costwise). Maybe this whole diy thing is not feasible.  IDK but what are your thoughts....

I started with something in CAD .... 
however your articles are very interesting!! awesome work on your horn system. that is legit!!
