Atlas Sound has also addressed retrofit and “division of labor”
installations with a new “motorboard” version of the Strategy Series® II.
Model FA42T-6MB is comprised of a 4" speaker with transformer,
selector switch, and front plate. The footprint of the FA42T-6MB is
identical to a standard FA Series 6" speaker component, which allows
the motorboard to fit into all current Strategy Series® 6" enclosures in the
exact manor as a regular FA speaker. Front mounted tap selector switch
for easy system tuning adjustments includes transformer bypass setting
for 8Ω / direct coupled operation.
