This is a Rectify Series drop-in speaker system for Atlas Master S2/S4 locomotives. The speaker uses the factory mounting screws and no modifications are needed!
The new reversion works for both sound-ready/equipped models; the earlier PCBs with bare wires and clips and the curent PCBs using 2-pin connectors for the wiring.
The speaker comes fully assembled and tested.
Dimensions are 9mmH x 17mmW x 32mm
