Okay, I think I understand what you are saying. However, I wonder why this
is a problem with an array but not a single element? Wouldn't the
reflected, off axis, time delayed sound also create a combing effect with a
single diaphragm? I would think that with a large array combing effects
could be reduced if all the mic elements are not in the same acoustical node
or antinode, thereby averaging things out over the area covered by the
array.

This is true for audio that is sourced perpendicular to the diaphragm in
the capsule. The problem is reflected
sound that enters from an off axes point. That sound would setup the
comb effect due to the difference
in time that the sound reached the individual capsule diaphragms.

this so let me know if I'm wrong. This applies to speaker line arrays so I
assume that it's also true for mic arrays.)

The comb filter effect would kill anything that would sound liek music!!
