sound decoder ?

[NW Modeling List]

I concur with Nigel’s general approach.  But the opening of the speaker enclosure must be situated at, or at least aimed at, an opening in the model, like a hole through the stack, or the gearbox opening in the bottom of the boiler in a steam loco—or an open radiator opening, or the frame opening for one of the trucks in a diesel model.  Less obstruction between the speaker enclosure opening and the outside of the loco is better, in general—so the stack opening is less likely to be optimal than the gearbox opening in most HO models.  Less distance between speaker enclosure opening and the outside of the loco is also better, in general.

Can anyone relate this to Lionel "Fat Boy" speakers. I can't see that
small stuff anymore. ;)

Hi Jimmy;

Get the largest speaker that will fit, and put it in the biggest sealed box that you can.

Put a second small speaker under the stack or similar location - also in a sealed box.
