This is a Rectify Series drop-in speaker system for Broadway Limited NW2/SW7 locomotives equipped with Paragon decoders. The speaker uses the factory mounting screw and no modifications are needed to replace the factory speaker.
 
These do not fit the early QSI-equipped BLI models, as the decoder takes up the entire length. For QSI-equipped models, use the UFIT-0935 as suggested in the 21-pin installation design (coming soon).
 
The speaker comes fully assembled and tested.
