This is a Rectify Series drop-in speaker system for both current-run Walthers Mainline and older sound-ready Proto2000 F-unit locomotives. For the current-run Walthers Proto F-units, use WLPR-F701-RC1.


The speaker uses the factory mounting screws and no modifications are needed to replace the factory speaker.


The speaker comes fully assembled and tested.
