This is a Rectify Series drop-in speaker system for Intermountain F-Unit 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.


Dimensions are: 12mmH x 26mmW x 32mmL
