So you are saying that loudspeaker timing has to do with the audio
signal going to the loudspeakers

No, it has to do with the sound coming out of the speakers. The timing of
the sound coming out of a speakers is partially determined by the signal
going into the speakers.

and not the actual speed of the sounds coming from the drivers.

The speed of sound is essentially the same from all of the speakers in the
system.


I made the false assumption that
different frequencies of sound traveled at different speeds.

Yes, you did, and thank you for seeing your error.

Why are
the signals going to the woofer and tweeter not aligned with one
another?

They may or may not be aligned with each other, depending on the crossover
system design.

One effect you haven't mentioned is the fact that the time delay between the
electrical signal going into the speaker, and the acoustic signal (sound)
coming out of the speaker also varies with the speaker type and frequency.

Does the crossover network cause a phase shift in the
signals that pass through them?

Yes.

Speakers and their design really fascinate me but there is much I need to
learn.

Do you know of a good website that explains the whole timing issue?
