This is a Rectify Series drop-in speaker system for Atlas Master HH600/660 (QSI) 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 features a notch to properly locate the front LED headlight. The speaker mounts in the factory location with a touch of adhesive and requires removal of the QSI sound and a new hardwire decoder installation.

 

The speaker comes fully assembled and tested.
