MOTORBOARD ASSEMBLIES

Atlas Sound has also addressed retrofit and “division of labor” installations with a new
“motorboard” version of the Strategy Series II. Model F42T-6MB is comprised of:
4" speaker/transformer/selector switch and front plate. The footprint of the F42T-6MB is
identical to a standard FA Series 6" speaker component, which allows a motorboard to fit into
all current Strategy Series 6" enclosures in the exact manor as a regular FA speaker.
