Scale Sound Systems ALMA-UNI1 Atlas Master Universal (U23/30/33/36B, B23/30-7, RS3, others) HO Scale ALMA-UNI1-RC1

This is a Rectify Series drop-in speaker system for most current-run Atlas Master locomotives, such as the U23/30/33/36/B, B23/30-7 and many others using the "standard" 16x35 Atlas enclosure. More than just a box, the enclosure features Diapasonic Tuning™, which allows the lower frequencies to accurately develop and resonate, clears the midrange of excess resonance and tunes the upper-mid/high response.

ALMA-UNI1-RC1 is "deck-mount" and should be used if your locomotive's speaker is mounted to a "shelf" on the frame as most of them are. The speaker mounts with double-sided mounting tape or a strap of tape over the top.

While these speakers are based on the typical Atlas 16x35 factory speaker, smaller Atlas switchers utilize different speakers. I offer these as well, such as the S1-S4, HH600/660, MP15 and others, in addition to various early-run pre-sound and QSI-era Master locomotives.

These speakers have a notch to facilitate the stock 3mm LED. If your model's rear headlight does not need this notch, you could simply use a UFIT Standard speaker, particularly if your model has extra available space (height and/or length). https://www.scalesoundsystems.com/product-page/ufit-universal-standard

The speaker comes fully assembled and tested.

Dimensions are: 11mmH x 17mmW x 40mmL
