Developed in cooperation with a few Austrailian modelers, this is a Coeval Series drop-in speaker system for Auscision 48, 830, X Class and possibly other locomotives.
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: 10.5mmH x 16mmW x 35mmL
