Heck if I know... OK

(1) some folk have the misimpression that clipping is always a harsh high frequency experience. If clipping is resulting in an dc offset driving a woofer's neutral point forward (or backward) in the gap, the observation of the distortion would manifest itself as a much subtle distortion such as a change in timber. And the effect would go away once the clipping conditions alleviates itself.. Tube Amps are not immune either - the DC voltage will saturate the output transformer.
"The DC component is a very sensitive parameter and a small DC bias
can lead to the complete saturation of the magnetic core of the
transformer with the generation of harmonics (distortion of signals).
The order of magnitude of the DC current necessary to saturate the
transformer is the same as that of the transformer no-load current i.e. a few % of the nominal current."
