This is a Rectify Series drop-in speaker system for Athearn Genesis F-Units that have the early, pre-sound frame (no cavity for a speaker in the rear). 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.


The speaker comes fully assembled and tested.


Dimensions are: 10mmH x 26mmW x 32mmL
