    Refoam question

    My 2235h drivers are needing re-foamed. From over here in Bonny Scotland ( A Nation not a County ) the easiest source seems to be Orange County SR. Are these righteous or is there a better source. Im sure there is some experience in this forum in this regard . Thanks boys and girls.

    One of the forum's most popular sources for refoam kits is Rick Cobb: [email protected].

    Could someone post the web-adress/homepage of Rick Cobb or other suppliers of quality DIY refoam-kits for JBL?
    There seems to be a lot of suppliers out there, but it's hard to tell which one sells top quality (or original?) stuff.

    I have a pair of JBL L166 (woofer 122A-1) that needs refoaming. Since I live i Denmark, I'll prefer someone with a web-shop-service.

    Thanks!

    The "mail to" link that is.
    Not the "www"-link (=link to homepage)

    Cool Second that too

    Well, in the broadest sense you could call this Mr. Cobb's website.

    You're welcome

    Digging up his feedback you'll find a LOT of forum members among his happy customers. Hey, I'm on page 25 in the meantime along with mbake, or Robh3606..

    Some pics added for Claus' belief how 122A-1's look like, with these kits. Make sure to tell Rick the correct woofer type. I believe there are slight differences in the 122x 12" cone diameters.

    Then, in case you want to employ a pro with this task, find someone who is able to refoam them without removing the dustcaps - it's not neccessary for centering. He should also be willing to scrape off the old surrounds from the backside of the cone, and stick the new surrounds on there where they belong - and not take the lazy route glueing them to the front.

    Thanks for info and pics. They look very fine!
    Though first time, I'll mount the edges myself. And if it fails, I can always ask a pro to take over.
    Do you know, if - and were - I can get the gaskets.

    Mine looked close to that

    For DIY, you might do a search for 'resurround step-by-step' here - and Bo's detailed guide should show up.

    BTW I shouldn't forget to mention that JBL won't recommend refoaming your woofers. For a like-new unit a full recone using a JBL kit might also be in order, to make sure the spider and voice coil match the factory specs. Just for the record, thats the big solution - and the costlier one. If there isn't any voice coil rubbing and the spider isn't sagging already, you can have excellent results with a refoaming as well.

    For the gaskets - anyone else? Mine were reusable.

    Not sure if the 122 Gaskets are still available. The gasket sets for the 128H / H-1 should work. Check with a local JBL service center and ask about ordering the parts. The U.S. Pro Part # is 52806 for the 128H and you will need 8 all together.

    Still optimistic...

    Nice to know that yours looked just as bad - and came out so sweet!

    Voice coil seems to travel OK and spider looks fine too.
    Here in DK a re-cone job is about € 200-250,- per speaker, so it'll be the DIY-re-edge way first.

    Btw: One of the LE5-8s need a re-cone-job - the structure of the cone is "soft" in one side. Might be better to get another (used) LE5, but I'm not certain of the different versions (LE5-2, LE5-8, LE5-12 etc.).
    Does a scheme or list exist?
