I know they knew a lot in those days and could have dealt with the nonlinearity of air if they wished to or if there attention was drawn to it.

Actually, you are right. The problem during those days was not with shortage of knowledge but with absent of needs to do better then they did.

Actually air is nonlinear with a uneven order nonlinear connection between pressure and volumen by audio frequencies at least. An uneven order nonlinearity produces even order distortions, this might explain our preference for single ended devices, that predominantly produces distortion of the same nature as air. Our brain have due to natural selection been optimised, with ease, to filter out excactly the kind of distortions that dominates the medium that we are in: Air. It would be to our disadvantage if we just by being, would get a headache due to the overload of our signal processing device between our ears.

I understand it very well, but you also have to take under consideration that no one even approach to construct of driver-horn as Sound source but they rather treat it as a pressure transducing system.

More down to normal engineering: Manufacturers of compression drivers have in the "recent" years introduced drivers with short throats and larger flare rates to measurebly minimize the amount of produced distortion that stems from airs pressure nonlinearity.

Yes, I know about it, but at the same they a lot of other “inventions” that do not work out… Anyhow, Erick, let keep this thread dedicated to Jessie’s project.
