Developed in cooperation with a few Austrailian modelers, this is a Coeval Series drop-in speaker system for various Auscision locomotives using the 20mmW x 40mmL enclosure. It appears this system will fit the following models:
NSW 421 class
NSW 422 class
NSW 43 class
NSW 46 class
NSW 86 class
NSW V-Set Interurban Passenger
GT46C-ACe (enclosure in the fuel tank)
The speaker uses the factory mounting screws and no modifications should be needed to replace the factory speaker. Alternatively, the screw-mount tabs on the sides may be carefully trimmed off if required.
Since I have no first-hand experience working with Australian models, please note the dimensions and shape of the system in accordance with your particular locomotive.
The speaker comes fully assembled and tested. Please choose 4Ω (Loksound) or 16Ω (Soundtraxx) wiring.
Dimensions are: 11.5mmH x 20mmW x 40mmL
