This is a Coeval Series drop-in speaker system for early-run Atlas Master Dash 8-40C locomotives. The speaker is a beautiful fit between the front weight and motor mount and uses a touch of adhesive on the feet to secure it to the frame. No frame/weight/shell modifications are needed! The factory PCB will need to be removed with a hardwire decoder installation.


The speaker comes fully assembled and tested. Please choose 4Ω (Loksound) or 16Ω (Soundtraxx/TCS) wiring.
