Got it in one! Exactly analogous to push-pull cancelling out even
harmonics in a class-A amp.

So, improved fidelity of the bass waveform, then. Do drivers typically have
inconsistencies in response that are dependent on the direction the cone
moves in?

Things are always clearer in the cold, post-upload light.




Well they shouldn't have of course!

In general the magnetic flux isn't symmetrical each side of the cone
resting position, so drivers do produce even-order distortion even at
low levels. At high levels more non-linearities come into play of
course as the cone hits mechanical limits, and the coil comes out of the
main flux area of the magnet gap.
