This is a Coeval Series drop-in speaker system for Atlas Master Dash 8-40C locomotives that use the dual-round speakers behind the cab. 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 mounts over the rear drive shaft with a touch of adhesive 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.
