Scale Sound Systems Speaker SXTH UNI1 Scale Trains EMD SD38-2, SD40-2, SD45, C39-8 Dash-9 GE ES/ET/GEVo/Tier 4

Scale Trains Universal #1

NOTE: the latest run of ES44s has a speaker design like the GP40s. This UNI1 fits without using the screw-mounts just as it does in the GP40, but a new speaker specifically for the new-run ES44s is available in another listing.

This is a drop-in speaker for all Scale Trains locomotives that use the 4-screw mount sandwiched between the frame-halves. This speaker features Diapasonic Tuning™ and provides a deeper, clearer, smoother sound with more detail over the stock speakers.

The models that use the 4-screw mount include:

EMD SD38-2

EMD SD40-2

EMD SD45

GE C39-8

GE Dash-9 (later-runs, maybe others)

GE ES/ET/GEVo/Tier 4

All of the SD40T-2 Tunnel Motors use the 3-screw mount speaker, available as my SXTH-UNI2-RC1.

Note that some of the stock sound-files do not have a very strong low-frequency response. While these speakers WILL improve the depth of sound and overall sound-quality, they cannot produce bass when there is no bass to be reproduced; they can only better reproduce what they’re being fed. Sometimes loading a different sound-file (noting the function programming SXT uses) will result in a more enjoyable sound.

The speaker comes fully assembled and tested.
