I think at this point, it's enough and I'm like totally confusing RF
and audio I sure. :>)

They both obey the same rules but the wavelength of audio frequency is
much longer than RF tending to negate transmission line effects, and
both capacitive and inductive reactance are much lower at audio
frequencies tending to minimize phase shift effects.

The phase shift with the induced back EMF on the speaker wires occurs
because of mechanical delays in the speaker cone, not because of
electrical reactance.

Don't forget though - you've got some passive crossover network componets at
play here also that add both inductive and capacitive reactance. When you
think about it, this whole circuit gets very complex with all kinds of phase
shifts going on in the dynamic mode of music reproduction. I guess that's
why the audio engineers make the big bucks.
