About a year or two ago, I bought the line Chief plus version of the New Jersey Central Blue Comet and was overall very, very satisfied with it. For some time though, it seemed to me that the chuff was not at the same volume or intensity as everything else, and was wondering if this is a speaker or rather a technological problem... If it is a speaker problem, does anyone know where to get a good quality speaker that is 2 1/4"( the louder the better for me) , and if technological, should I just bring it to a professional?
