NASA Hardware - Apollo Launch Control Center MOPS Communications Audio Speaker

This artifact was removed from a NASA Apollo LCC Communications Box .

It consists of a plated steel frame, fabric voice cone, finely wound copper coil and an Alnico speaker coil magnet.

The fabric cone shows signs of damage.

NASA Kennedy Space Center sold these artifacts back in the early 1990's where I purchased them. 

Over the years NASA KSC retired the units.

The basic measurements are:  3.0 inches square by 1.6 inches deep.

All of the Apollo Saturn Spacecraft launches audio communication were sent through this device and others like it.
