[C320-list] Replacement of Poly-Planar MA4055 Cockpit Speakers

[Cliff Lee]

As followup, I sent a note to Poly-Planar and talked to Krystal Welch in
their accounts department.  She had a few "warranty" speakers available, so
I am buying those.  FYI, the factory that produced these speakers closed
down recently.  Since demand was good, they are gearing up another factory
for replacement but they won't be available till some time in 2024.
