When faced with another JBL find, Good mech986 says , JBL Fan mech986 says
Rick Cobb also sells the dust caps for $4 per piece. I just recieved them today.
I tried refoaming a pair of 136A'S a few weeks ago with one of his kits. Instead of using tone cd supplied I tried shimming, one was no problem the other not so good fot it has a slight rub. I got another kit, this time I will try tone cd and see if it works better for me
Dang. I mentioned I had a dent in a dust cap and he never mentioned he sold them Oh well. I plan on grabbing another set of surrounds and a CR82235 recone kit just to hang onto down the road. I am going to see if I can get the dent out then go from there.
Here is a pic of the rear of the cone with as much of the surround off as I dare to try.
Should I try to get more off? If so how?
Here is a pic of the pair
And here is a snap of the serial number badge on one.
Rick shipped my surround kit today so here is to hoping Canadian Customs doesnt hold it long
I think I will just stick with the test tone route. Seems easiest and looks like it works well
Hey Turtlewax. That dinged dome is easy to fix with a vacuum cleaner. Just suck it out back to its original shape.
Sweet!

With foam that old and crumbly, rubbing it all off with your fingers is sufficient. The picture appears that you got most of it removed. The glue applied for the new surround should bond with any viable foam or glue that's remaining.
I found that when it's still a little gooey, I seem to get better results using a little MEK on a qtip to remove as much as possible.
Unless you were going to cut off the dome and use shims instead of Rick's tone cd, you're correct to leave it be until you get the surrounds replaced.
Thanks for your input. I was not sure if the cone could take any MEK without damaging it. I will try with a qtip to get the last remnants off. I wont push the issue either as I am sure the new adhesive will bond fine, and again your input reassures me
I grew up with these speakers lingering in the background, although never used much, and I always knew they were special. I don't think my Dad realized that new speakers weren't better either. He bought a few sets here and there and the funny thing is these just crushed them for SQ. I feel a responsibility to restore them and share their abilities with a new generation.
I had a set of Paradigm Monitor 11's in my HT room for fronts, and I am flabbergasted at how much more the L300s bring to the sound stage and how much more full and warm they sound. Just need to find a center that compliments the sound and has a finish as beautiful.
Thanks for all your help folks. Really loving this forum
Hi turtletrax.
I thought I blew my re-edge job on one of my 136A's. As it turns out the glue holding spider on the frames was dried and crumbly, approx 2/3 of the spider was basically flapping in the breeze. I pulled the other driver and sure enough the same thing was happening but not as advanced.
You may want to check that before installing your new surrounds. Both the spiders appeared completly flat, but when trying to get a knive under where they loosened, the problem was super apparent.
Well, I am happy to say that I received my kit from Rick and it was perfect. Awesome packaging, quick shipping and exactly as stated. I had everything prepped but no matter where I looked I could not find MEK in my area. I scraped what I could of the remaining adhesive from the basket and cone and gave the basket edge a light sanding and went for it.
I have them running the test tone now and one was "ticking" so I found the area that was slapping and re-glued it. Other than that it was actually quite simple
I also checked the spiders as per Perchdog's recommendations and they are fully glued. So I think my last question is how does one know if the magnets are in need of remagging? I am pretty sure they were not abused enough to require it, but would be interested in knowing if there are any clues.
Thanks for all your help everyone!
Edit: I almost forgot to say that the dent in the dust cap popped out when it got the 30hz tone Might have to buy a lottery ticket today!
