I am a newbie here. I have a pair of Lancer 33s that belonged to my father. They need a refoam. The drivers do not have any markings on the back as to which version the actually are. The back of the cone has a number printed on it "LE8101." I am assuming that any LE8 refoam kit will work? In looking at the driver, I am a little confused. The dustcap does not appear to be felt because it is too smooth. Could it have been an aluminum cap that was painted at the factory? I am going to attempt to do this without shimming, but I want that option available just in case. I would like to know if I will need to order the aluminum cap or a felt one.
Also, I was contemplating adding a tweeter to this and building myself a different box and crossover. Has this been done before and can someone point me in the direction of a write-up if there is one?
Your help is greatly appreciate
