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.\u003c\/p\u003e\n\u003cp\u003eThis speaker is available in two versions and\u003cspan\u003e \u003c\/span\u003e\u003cu\u003ethe \"deck-mount\" should be used in 90% of applications\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eeven though the stock speaker uses screws\u003c\/strong\u003e\u003c\/u\u003e;\u003c\/p\u003e\n\u003cp\u003eALMA-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.

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.\u003c\/p\u003e\n\u003cp\u003eThese 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\u003c\/p\u003e\n\u003cp\u003eThe speaker comes fully assembled and tested.\u003c\/p\u003e\n\u003cp\u003eDimensions are: 11mmH x 17mmW x 40mmL\u003c\/p\u003e","brand":"Scale Sound Systems","offers":[{"title":"Default Title","offer_id":54112090128659,"sku":"ALMA UNI1","price":20.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/9283\/4323\/files\/SSSALMAUNI1.png?v=1777922517","url":"https:\/\/southeasthobbies.com\/products\/scale-sound-systems-speaker-wlpm-uni1-walthers-mainline-gp9s-and-sd70ms-and-proto-u30bs-gp20s-sd9s-and-some-gp30s-copy","provider":"SoutheastHobbies","version":"1.0","type":"link"}
