Mine also both came with a rubber gasket, which I have no idea what that is for... Anyone?
that rubber gasket is not needed, but is made to be used in a front loaded cab, ala jerry's, inbetween the speaker frame and cab. on a rear loaded cab the cork gasket is utilized.
I also got some rubber gaskets with my speakers and thought that was what they were for. They seem very breakable and when I tried to affix one of them I feared it would snap, so they sit in the box. Also, when I got the last "near new" JBL it seemed like there was something inside of the magnet, cloth like if you look through the mesh on the sticker label side you could see it floating around in there! This scared me at first and I almost returned it but it sounds fine and seems not to affect the speaker at all?
