This is a Rectify Series drop-in speaker system for all Athearn Genesis SDP40F/SDF40-2 locomotives. 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. The speaker drops right-in and no modifications are needed to replace the factory speaker.


This is the TALL system only, installed in the front speaker cavity.


The speaker comes fully assembled and tested.


Dimensions are: 28mmDia x 17mmH
