Reply to "Speaker replacement for UP SD90 proto 2 engine"

Chuck SartorOGR Forum Member

Ted, I think someone gave you some wrong information. I looked at my SD90 that was originally proto 1 and converted it to proto 3. The speaker housing is for the standard 50mm speaker. MTH BF-0000033 which is available from MTH. It is not the original type but more of a pancake speaker, just won't be as loud. There is a guy on the internet that sells speakers like the original type plus wiring harnesses. I forgot who it was, but maybe Gunrunner or GGG knows who it is.
