channel to the
other (or indirect -- reflected -- radiation from itself) is
absorbed and reradiated.  *** SUPERPOSITION ** is the mechanism.
Much in the way two different frequencies can be radiated from 
the same speaker driver at the same time, the "original", and
picked up energy can be radiated at the same time.

My AR-9 speakers have a 12" woofer firing sideways from each side of
each enclosure.  The right woofer of the left speaker points *directly*
at the left woofer of the right speaker!  The "outside" woofers
point at themselves off the wall in their respecive directions!  The
frontal mid and high range drivers coming off the front all point at the
same (far) wall! (Reflecting back to themselves, and the other one.)

Anybody want to discuss removing one channel's worth
of speaker (running MONO) to see if that helps (long live mono)?
How about those reflections to itself?  Double blind tests to see if
you can tell if ALL the speakers are missing or not? :-)

There is a lot of room for more interesting discussion -- in this
direction -- should the net desire to further pursue beating that
extra speaker to death.  Let's talk of the forgotten *Pile* of extra
speakers . . . .
