This is a drop-in speaker for some 2025+ release Scale Trains ES/ET locomotives that use the redesigned 4-screw speaker located under the rear radiator weight, on top of the main weight. This speaker replaces the entire gray radiator weight, fills the open cavity below and screws in-place with the factory screws. No modifications are required. This speaker features Diapasonic Tuning™ and provides a deeper, clearer, smoother sound with more detail over the stock speakers.
This speaker does not fit earlier runs where the stock speaker is sandwiched between the two, large, weight-halves. Presence of the gray radiator weight is not an indicator, as these models have had that weight from the beginning.
The speaker comes fully assembled and tested.
An install guide will be available soon.
