Lets get back to the OP’s question.
It seems to me, however, that live music isn’t time aligned. Suppose I’m playing the piano and you’re sitting across the room. When I stretch out my left hand to hit the low notes, those notes travel along the same long, slow wavelengths as the notes from Wilson’s woofers. Similarly, the treble notes I play with my right hand move quickly through the short wavelengths. The notes from the piano are naturally out of alignment.
There is not “slow and quickly” happening as the frequency changes.
The notes all travel at the same speed across the room.
If the woofer and the tweeter are both involved, with say a note in the middle of the cross over, then we want both of those to be launched so as to arrive at the ears in unison.
Hence this is fractions of an inch or a few inches at most.
One usually either steps the speakers spatially, or with a tilt, or uses a DSP to align them electrically. And each sample of a 44.1 kHz signal is roughly a 1/4” from the previous or next sample.
