Scale Trains Universal #1
This is a drop-in speaker for all Scale Trains locomotives that use the 4-screw mount. 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 and at least the first-run of Dash-9s use the 3-screw mount speaker, available as my SXTH-UNI2-RC1. Later runs of the Dash-9s use this 4-screw speaker. It is recommenced that you take a peak at your Dash-9’s speaker to ensure you order the correct one. In the event that you do not order the correct mount, the screw-tabs can be nipped-off (do not break-off) and the enclosure secured into the locomotive with a bit of double-sided adhesive.
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.
Dimensions: 12.5mmH x 16mmW x 25mmL
