I was thinking ESD drivers may have a true advantage over ALE/GOTO/Others (apparently they actually know how their drivers work) if that allow to someone design the horn exactly the way he/she want, and later order the driver with custom specs to match the horn.

I think it is a fallacy to think this way. There is absolutely no mystery to “design” a horn to meet a compression driver specifications, you do not need to know “how drivers work”. The reversed scenario is more complicated. Sorry, but I do not believe in custom specs compression drivers. Even if the money is not object and the makers have knowhow and desire to meet a custom specification then I do not feel that makers can meet any lucid truly custom specification. The makers do have a very limited set of criteria that they can manipulate and the resulting drivers sound as they sounds. That is it. If you need more second harmonics in upper range, more warmth at 300-600Hz, drop “color temperate” all over lower region, Ormandy/Philadelphia -like sound in midrange or more emphasized resonance at second high-pass octave then no makes would be able to accommodate it. They can theoretically tweak a sustention to give you another half octave at the bottom or change geometry of the phase plug to give you something at the tope but it will change the whole driver sound and there is absolutely no one who can surgically inflict to a compression driver any custom sound.
