Why would it be nonlinear, though? I'd expect the deflection to be pretty linear until you get near the elastic limit. Which you don't want to do because you'll stretch or break the diaphragm.

What I mean to emphasize is that suspension equals compression and thus less dynamics.
The one who succeeded was the one who didn't know it was impossible.
Is it? I always assumed it was pretty close to Hooke's Law, that is, linear. In two dimensions, of course, with more compliance laterally than vertically.

You could though try to integrate Hooke's law into the calculation of air volume that is very non linear for a suspended membrane.You probably understand me now? :)

Sure. The next question, then, is which distortion mechanism predominates at high excursions -- the nonlinear displacement, or the nonlinear magnetic field?
