The temperature of the driver can cause a lot of difference in the stiffness
of the suspension. A voice coil can be quite a heater. I'm not sure I would
want to rely on that though. If you have the means to measure Fs accurately,
try measuring it after the driver has been in the freezer for a while. The
measure it again, after it warms up.
