How do I know what year mine are made in? I was going to update the crossovers but since these appear to be newer than my 1978 LaScalas I am not sure if it is needed quite yet. Could I just wait till I go with some nice new crossovers for the LaScalas and then do these? The caps are little black rectangles. The tweeters are k77m, mids k55m, woofers are k42e. The crossovers are type HIE.
