Back in the sixties, I worked for a background music provider. He
used dual coil speakers for his customer installations.
Reason for the dual coil was:
Voice coil one: was for the music which the individual area
user could control the music level.
Voice coil two: was for the public address system which the
area user was not able to control.
In the 2-way radio application, four separate radios could use the
same speaker.
