Most releases from 2024 onward use the newer AHRR-UNI1. Units prior to 2024 use the AHRR-3845. Check your chassis to compare photos.\u003c\/p\u003e\n\u003cp\u003eMore 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. The speaker uses the factory mounting screws and no modifications are needed to replace the factory speaker.\u003c\/p\u003e\n\u003cp\u003eAn optional front-mount speaker may be added to many of these locos. This speaker is designed to replace the small weight (Athearn part #88550) that I have seen used in RTR SD38s and SD40s and has dimples to accommodate the screw-posts. A bit of double-sided tape or a dab of adhesive secures it. It is not recomended to use the front-mount speaker alone.\u003c\/p\u003e\n\u003cp\u003eThe speakers come fully assembled and tested.\u003c\/p\u003e\n\u003cp\u003eOverall dimensions are 18mmH x 18mmW x 47mmL\u003c\/p\u003e","brand":"Scale Sound Systems","offers":[{"title":"Default Title","offer_id":54111521145107,"sku":"AHRR 3845","price":20.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/9283\/4323\/files\/SSSAHRR3845_bdcb6210-3616-4dff-afae-c7870cbb196d.png?v=1777908529","url":"https:\/\/southeasthobbies.com\/products\/scale-sound-systems-speaker-ahrr-3845","provider":"SoutheastHobbies","version":"1.0","type":"link"}
