This is a Rectify Series drop-in speaker system for Athearn SD50/60 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 uses a touch of adhesive to mount and no modifications are needed to replace the factory speaker.


The speaker comes fully assembled and tested. Please choose 4Ω (Loksound) or 16Ω (Soundtraxx) wiring.


Dimensions are: 16mmH x 18mmW x 55mmL
