Note the first photo shows the original Rectify model, while the second photos shows both Rectify and Coeval in a Genesis GP15 installation. These speakers fit both Genesis GP7/9 and GP15 locomotives.


The speaker comes fully assembled and tested. Please choose 4Ω (Loksound) or 16Ω (Soundtraxx) wiring.
