Not easy to put the glue on the backside of the cone,
because of the frame. Did anyone tried an injection needle ?
The glue smells like wood glue. Is it nearly the same ?
See the black shadows around the mounting hole.
How can i remove this ?

When I did my 2231's I fitted the new surround loosely in place and then turned the speaker on its face. To keep the surround clear of the working surface I supported the outer rim of the driver on two pieces of the mounting gasket that is provided so the speaker can be mounted from inside the cabinet. With this setup I had access to the rear of the edge of the cone except that the foam was in the way. I needed a tool I could use to fold the foam back that had no sharp edges or points that could catch in the foam and tear it. I had two that worked perfectly; one was a tack remover, which is like a screw driver except it as a thing kind of like a hammer claw at the end instead of a blade. The other was the bottle opener on the Leatherman my son gave me for Christmas last year. With the tool in one hand and the glue bottle in the other I was able to pull the foam back just in front of the glue spout as I moved the two together along the edge, working between the struts of the frame. With a little practice I became adept at reaching behind the frame members to apply glue to that part of the cone. When I had finished a section I put down both tools and picked the driver up with both hands and set it down again on the pieces of gasket in another position. I worked as quickly as I could so that the glue would not set up before I was all the way around. I then turned the driver onto its back again and repeatedly pinched the foam against the glue as described by Bo until it set up. This method worked very well for me.

Look what happend to my 2. LE 10A
What can i do now ?? Not refoamed now.

Ouch ! Sorry to see that has happened .

IME: Not much you can do / if anything to fix that frame .

If the cone still works without rubbing - I'd use it as is . If the frame edge was "bent" in the mishap ( usually happens ) then you may need to mount the speaker with an extra thick foam gasket - to create a good seal. You may also need to use mounting clamps instead of just the screws/bolts - to keep it in place .

JBL used to sell just a replacement frame assembly for the LE10a.

It was number MS20577. ( in a 1980 parts book )

I looked into getting a replacement frame for a similar type break . (eBay )

I was told by JBL Canada - that this part or its' newer part number is not available .

Paragon........Try JB Weld. And use alot onthe back side as well as on the broken edge. later you can file for a smoother finish. Ive repaired engine blocks with this stiff and it holds.

Dood!! What a drag!

How did that happen? Ouch!

Here's a Link for JB weld - if you need some shipped across, lemme know. I've not tried it, but Maron seems quite fond of it!

http://www.jbweld.net/ - "Find a Dealer" shows it can be found across the water...

Good luck!

[paragon]

Thank you all for help !

There must be a "haircut" (?) before it`s broken.
Falling down on the table right on this edge from a height of 4 inch or so.
This edge is a little "deformed" (if you understand), so the driver must had fallen down before i bought it.
Try to find some "metal glue" here and will fix it.
Driver is still working witout rubbing or noise.

Best Regards

By the way,

Other speaker is working very well. Glue is dried and every thing is ok.
Time was about 2 hours to fix the new foam without cleaning the driver.
Put the glue very thin on the backside and the basket.
Put to much glue to fix the rubber ring, so i had to remove it with a wet cloth from the basket and the surround.
But all is looking good now, glue dried clear and you see nothing.
Surround is a very good matching part (Thank`s Guido).
