It's not just the frequency of vibration that matters, but also the impulse response. Theoretically, transducers are limited by the fact that you can't replicate immediate changes in velocity while you're working with something that has mass. Even if we accept that over 20khz frequency changes aren't perceptible even in transients, FR up to that range is very inconsistent. Nonlinear in this context would be the change in FR when measuring at different amplitudes, which would include resonances for example.

I'm glad you backed off the speed issue. I think it is reasonable for people measuring headphones to assume that most listeners will generally tend to listen at a generally loud but safe volume. But my original point was not a defense of measurement, but an explanation of some illusions created by the designs of different headphones.

Yeah, I'm not completely sold on speed myself, I just think it's an additional potential source of inaccuracy in how we measure FR. I just wanted to emphasize that measured FR is lacking, so there are perceived technicalities, but those technicalities are also just un-measured FR.
