This is a Rectify Series drop-in speaker system for early-run Intermountain GEVo ES/ET locomotives (28mm-round speaker). 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.
This model is available in two different voicings. While subtle, the "Bright" voicing is geared for Loksound files and helps provide a clear midrange and brighten the higher frequencies. The "Natural" voicing has a more throaty midrange and natural high frequency response geared for Soundtraxx or TCS. Both models feature the stout low frequencies Scale Sound Systems is known for.
The speaker comes fully assembled and tested.
Dimensions are: 19.5mmH x 18mmW x 43mmL
