NOS Woofer for a JBL L100 - do they exist?

Hey Folks,

My local electronics shop is trying to repair a blown woofer in a JBL L100. I'll take their word for it that it can't be repaired (or can it?).

Anyone know how to go about getting a replacement? I haven't looked on daBay, but the shop owner says he couldn't find any there. Any other sources?

You really need to send them to a JBL authorized repair shop, they are the ones who will be able to get the parts to do it. A quick glance at Orange County Speaker's website indicates that they are showing the 123A cone kit to be in stock. While not an endorsement of OCS, their site is handy to see what kits are listed as available and what are listed as aftermarket only. The $345 ea price is a hard pill to swallow to get them reconed, you could probably buy a pair of 123A off eBay for less than the cost of one recone.
 
OK, I had to look it up. It was in November 2010: $78.75 for the recone, with free shipping. It was a 2213H woofer (4311) but I believe the kit is the same. I guess it was aftermarket.

The current JBL Parts List has that kit priced at $327/ea. Either Parts Express used an aftermarket kit or they ate $200+ a driver on the deal.

But that is retail correct? Not saying that PE would eat wholesale costs as I'm sure genuine is cheaper than $327 wholesale, but not where they can do the job for $110. Seem to recall the 123a having the progressive/bell cone, similar to my 2213H. Aftermarket, I believe, are all flat/straight cones, which will have a different sound. And that doesn't even figure density, mass, etc.

I'm not 100% sure on the pricing. Since JBL will not sell cone kits to the public, I'm not sure they have a "retail" price.
 
I believe the "suggested retail" price includes the labor costs for the authorized service center to do the recone.
 
I have always understood that if the VC is toast, the woofer needs to be reconed, I guess because the VC and cone and spider are manufactured as a single unit.
 
You can rewind most voice coils, but you don't usually want to. It's a long difficult task that starts all over if you mess up, and won't last if you don't do it well. There are still a ton of them on ebay, so...
 
L100 woofers are very well designed and made, they are designed to be easily serviced. When I got my L100s, I had to remove the magnet in order to re-attach the coil to the spider, and with the magnet removed, you can see the coil. If you are lucky enough that the coil has burnt out near the end, you may be able to unwind a bit and re-solder it onto the lead out wires. You'll lose a few fractions of an ohm, but cheaper than buying another woofer.

Have a look at this thread.

I don't know about flat milled edge-wound voice coils. Where would you even get the wire?

I'm sure you can pay a bunch for 50 times more than you need somewhere. Just another reason why you wouldn't want to.

Leesonic, those are some great pics - it's always nice when people post quality photos of disassembled parts so others know what to expect. It does seem worth taking a peek at the voice coil. You would hope the shop already did that, but since they've already deemed it unrepairable without (as far as we know) any magnet or frame damage, and failed to find the truckload of replacements on ebay...

How do they sound...that is do you notice anything different then the original before they went south? From what I can tell they are probably using 2213 H recone kits from a MACKENZIE. If so I just wonder if these recone kits have the same T/S parameters as the originals.
 
They sound fine to me, but I did not have the originals to compare; I bought them damaged and had them reconed. The cones do have the original bell contours and ribs, by the way. The surrounds and dust caps look right too. I can't compare the color or texture to the originals, but they're not old and yellowed looking like some I've seen.
