This is a drop-in speaker system SET of TWO 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 SHORT + TALL system SET, installed in the rear/front speaker cavities.


The speaker comes fully assembled and tested.


Dimensions are: 28mmDia x 13mmH & 17mmH
