"Mark Simonetti"

Surely, as the lower frequency moves the cone back and
forth, which at the same time is vibrating to create the higher
frequency, that is IDENTICAL to moving a single vibrating source back
and forth, like the train analogy (except the train doesn't move back
and forth unless the driver is very confused). Therefore, the doppler
effect surely DOES occur.

It just seems really obvious, so I must be missing the whole point of
this, I'm no physics scientist !



** The matter is intuitive to many - but forever obscure to those with
no mental capacity to imagine the situation in their heads. It pretty much
divides up between the science types ( using mental, physical models ) and
the arts subject types ( using only grammar and phrase matching).

The fact that cones have **vastly greater** excursions at low frequencies
than at high ones - even for the same SPL - is at the heart of the matter
and clearly bamboozles as well.

The fact that those large low frequency excursions have the greatest
velocity also confounds the easily confoundable.
