This is a Rectify Series drop-in speaker system for Walthers Mainline SW-1 locomotives. The speaker mounts over the front truck and requires removal of the factory PCB and a hardwire decoder installation. Bits of tape should be placed over the frame where the speaker rests to ensure no shorting of the speaker contacts.


The speaker comes fully assembled and tested.


Dimensions are: 10.5mmH x 21mmW x 27mmL
