This is a Rectify Series drop-in speaker system for Athearn Genesis F-Units that come with factory Soundtraxx or are sound-ready. 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. A touch of adhesive secures the system. No modifications are needed to replace the factory speaker.
If you're using a short motherboard such as the Nix Trainz Decoder Buddy, or installing a hard-wired decoder, there is room to add the front-mounted AHGS-ACAB-RC1 speaker. If using a PCB-style decoder such as a PNP or Direct, there will not be room for the ACAB speaker.
The speaker comes fully assembled and tested.
Dimensions are: 14mmH x 28mmW x 40mmL
