Refoam question

[macaroonie]

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.

Arrrrr Laddie, why you no dry some sheep guts and rehang those wooferrrr suspensions? It's the Scot thing ta do! :p

[macaroonie]

As it happens I had some sheep guts for dinner WITH some American friends two nights ago. Yum yum.

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

I will second that!!! Rick's kit have to be the best out there and he knows jbl's and uses them as well. I just did my 12"s and working on my 8"s from my 4315B's and they fit perfect:bouncy:

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!

Look at your last post? The link is in there!!!

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

Well, in the broadest sense you could call this Mr. Cobb's website (http://search.ebay.com/_W0QQsassZlooneytune2001QQhtZ-1).

AH_HAA......... pay dirt , Thanks Fangio

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 :blink: 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.

[Fangio]

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.

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

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?

Yup - Zilch posted the link to the LE5 Matrix already.

Compare with system components in the L166 (http://manuals.harman.com/JBL/HOM/Technical%20Sheet/L166%20ts.pdf) Horizon tech sheet, below.

LE5-8 is the original. LE5-12's were recommended as exact acoustic and visual substitutes (and show up on ebay frequently, because this type was used in several speakers). Anyway, I'd wait for nice LE5-8's.

Much more difficult (and costly) to replace would be the 066's, pretty rare since no longer servicable from JBL nowadays. Hope yours survived both undamaged also.

Actually I found a "spare" set of L166 for very little money (w. one LE5-8 needing repair though, both woofers in need of refoaming and a wood-job needed also...) so I have 3 working 066-units.
I'll look for one more in order to reconstruct all four L166s.
Or I'll sell the second set as spare parts (but not in the near future).


Again - Thx for help!

Sorry to have missed this.

Anyone interested and/or so remote as to needing to try this themselves can get the kits from Rick and follow this Resurround Step-by-Step thread...

[Thom]

It's been suggested to me, that if one has never refoamed a pair of speakers, they should not break their cherry on an LE14. Any comment?

[John]

Funny you should say that!!! The LE14A's were the first pair I did and they turned out great. :D

[Thom]

Is there anything special about them? What I was told was that Le14, Le10, and Le8 were all trickier because of the ring that goes around the outside of the surround.

[Robh3606]

Hello Thom

The square frame drivers have almost no wiggle room on the frame for the outer edge of the compliance. You drop the surround in and it's damn near an exact fit. With the round drivers you have quite a bit more space to move the outside edge of the surround around. You need to get the surrounds well centered on the cone and go from there. I found them a bit more challenging than the rounds. What I do is fit them dry to get an idea of how well centered the coil is and to see how well the inside edge lays out on the back side of the cone. One thing for sure is get the backside of the cone as clean as you can.

Or, front side on LE14As.... ;)

Yes Thats just the way it worked for me. Also the smaller the cone the easy'r they are to do.:applaud:
