About those Vifa TC9 or whatever line arrays, the individual drivers will barely move. Isn't this where suspension nonlinearity, especially mechanical hysteresis will begin to matter?
Compared to a typical 5 - 7 in driver, there is an awful lot of rubber surround and spider to me moved -- by a very small signal!

I would think this is the ideal situation, regarding suspension nonlinearity - which I would think is something one starts to encounter for large cone movements.

Large number of drivers, moving within their comfort zone = good.
Large number of drivers, a few is not totally in line with the rest = defects will be attenuated by the natural midband SPL boost a line array provide.

Hmmmmmm.
I think bass modulation will get the 3" moving.
I ran 9 x 4".
Never heard a problem at low volumes.

Thanks for your input! I agree that small movement is ideal for motor / magnetic circuit derived problems. However, there is no small amount of mechanical hysteresis and related nonlinearity in the soft parts of the driver. I am particularly worried about this when there is no feedback mechanism to attenuate or sufficient excursion to break up low-level nonlinearity.
Allowing sufficient LF might actually a good idea to resolve this issue!
