Some time ago I bought some close out Vifa 5" speakers from Parts Express. They are labeled "JBL". These are plastic (excuse me, composit) frame with foam surrounds. They actually sound quite good - I used them in a home theater system. My question is, does anyone know the connection to JBL?? Did they at one time source speakers like this from Vifa? Certainly not the quality of my LE5's!
