Product Description
This is a speaker box for the 16x9x3mm speakers, custom designed for the new version n-scale Intermountain FP9 locomotives. This only will fit the locomotive version which has a circular speaker cutout at the rear of the frame. The enclosure is designed to maximize the air volume within the specific locomotive, in order to get the best sound possible. 

Length: 26.5 mm
Width: 16 mm
Max Height: 6.1mm
Air Backing Volume; 794mm^3

Minor modification of the frame is required by filing the rear PCB screw mounting point flush with the rest of the frame. (This box can not be used in conjunction with the PCB, only for decoder installs which replace the PCB (e.g. I use it with ESU Loksound decoders)
