Model FA42T-6MB is the entire 4″ speaker/ transformer/ selector switch/ front plate assembly found in the FAP42T assembly. The footprint of the FA42T-6MB is identical to a standard FA series 6″ speaker component. This footprint allows the motor board to fit into all original Strategy Series 6″ enclosures in the exact same manner as a regular 6″ FA speaker (FA136Txx).
