Soundbox - Sound for the Un-Soundable

[Tom]

Hmmm..... Interesting. This begs a question though, since my HO modeling is diesel, and my steam is mostly On30. Could you put more than one sound decoder in the box, say, in my case, a EMD turbo 645, a non turbo 567, a GE FDL and a Alco 539T and have one or a combination of them going at once for differing sounds on the same speakers? Or, would I need to build a different sound box for each type of decoder (in my case 4 boxes?)
