This is a Rectify Series drop-in speaker system for Bowser C-430 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 carpet-tape or a touch of adhesive to mount and no modifications are needed to replace the factory speaker.
You can choose to add a front-mounted speaker for better horn/bell localization by adding the UFIT-5318-RC1 which sits on the shelf behind the cab.
The speaker comes fully assembled and tested.
Dimensions are: 13mmH x 18mmW x 45mmL
