This speaker box is designed to fit sugar cube speakers used in model train DCC sound systems. This simple little box amplifies the sound of the speaker greatly. In tests, the output volume sounds are enhanced greatly by the speaker box which may need to be reduced by 50% because the volume is so loud. If this box does not fit a speaker you want to use, please contact us so we can design one to your specific needs.
This box is designed to a speakers specifications and may not result in the same results for your specific design.
