I purchased a pair of JBL 2245Hs for a speaker project that I am working on
(two full range speakers, these are the bottoms). One has a rub, so I also purchased a JBL recone kit from an individual (NOS kit). The kit did not come with shims for the voice coil gap. Does anyone know how thick/thin the shims should be? I can purchase some material and make my own I suppose if I know how thick they are. I have reconed spekers in the past, but I always had the shims.

Thanks.

The classic tradition for speaker voice coil repair 'shims" in the RCA Photophone Service Camp & also WEOC ERPIE / ALTEC has been a handy piece of 35 mm film always available in the theater projection booth.

Your kit should have a round clear plastic cylinder shim included with it. They use it to help pack the kit. Film sounds like a great idea.

Thanks. If only I worked at a theatre. :)

I will see if I can get some, or find that ring.

I've been known to use old playing cards, the thick cover from a calendar, and lately, the flyers that Comcast and others send in the mail. It only takes a little trial and error to find the right thickness.

For film shim stock, go to walgreens, cvs drugs etc or dollar store and buy a single, 75 cent roll of 35 mm camera film. it is all standard stuff
and it fits nice & easy.
