Had a friend look at my 2214h woofers today, he put a new spider in, attached the surround to the cone but before glueing the surround to the basket we noticed that the surround was about 1/8 or more raised above the basket. We were thinking that perhaps JBL used a cardboard spacer between the frame and the surround. If we do not use a spacer the cone will be pushed down as well as the spacer. I have been having problems with it bottoming out fairly easily and maybe at some point in the past someone had replaced the foam and did not use a spacer (if there is one).
