The deviation is dependent on the throw of the cone and the
modulating frequency (higher frequencies have a higher
first derivative, thus the associated Doppler will be higher)
These effects are highly implementation- and signal-specific.

Yes, note that our experiments cover a range of 40 dB.

40 dB? What exactly is 40 dB?

Sound level intensity. I think the actual SPLs were 78, 88, 98 and
108 dB, more or less @ 1 meter. RS SPL meter so its not excactly NBS
tracable,

What level was the first plot on your site (the one with the simple
4000 + 50 Hz signal) made at? (Approximate is fine.)

About 90 dN at one meter.

Also, as I asked in a personal email, if cone motion does not account
for the AM, then how would you account for it?

Speakers being speakers! ;-)
