Two other speakers theorists with who I consulted today confirmed what other proposed about. It looks like the negative effect of non-parallel axis is due to the dimension of diaphragm introduce “distance smear” when tilted. The same reason explains directivity and sharpening impulse response of axis. They might be right (and it fact they are right) but it does not work out for my own understanding. If the diaphragm distance smears the ONLY factor then the position multiple driver on curve point directly to the listening point should be the best solution of all – it is not the case practically. The second thing that controversial to me in this explanation – the geometry of the traducing surface should matter. Let take for instance my “Water Drop” driver. The ribbon is 21cm by 0.6 cm. In this case the tilting of the driver up and down should kill aliment VERY aggressively, and it does. However, considering a very small dimension in horizontal plane and considering its 120 degree horizontal radiation the tilting of the driver right-left should cause no time miss-aliment effect. Nevertheless it does.
Well, I agree to perceive that subject in the same way how I perceive allergy. I for years did not believe in allergies, considering allergies as a BS invention of US pharmaceutical industry. Then a few years ago I suddenly developed all kind of allergies. Now I do have allergies but I still refuse to believe in them. Ask me about allergies and I will tell you that is a stupid American invention… Go figure. I think I am a walking proof that Perception is Reality. But let it be our big secret... :-)
