I've never tried a "light" phragm in a 902, and since it was never a "stock" marriage i'm not inclined to venture down that path.
I'm keeping the light diaphragms in my 19's -- want to keep them all original and they sound so great "if it ain't broke, don't fix it"! I will probably still try installing the 902's from my 14's into my 19's just to see if I like the difference and at that point may have some decisions to make about possibly buying 902's for my 19's. BTW, RonSSS and the late Bill Eckle both seem(ed) to think light diaphragms were stock with (at least some of the) 902's at some point in time....
