Depending on the volume of play back there could be some transition in stiffness of the oscillator between the transient, and steady state portion.
Perhaps this variation in stiffness with displacement, along with the magnetic non linearities is what alters the timber so drastically from loudspeaker to loudspeaker, and especially from one design (ESL, ribbon, electrodynamic) so much.
