JBL D130 Factory reconed as K140??

[Toxophilite]

I picked up A JBL D130 recently that had obviously been re-coned as something else
I'm thinking a K140
It has a straight ribbed cone with a 'k' written on it in white(on the back), aluminum dust cap(a little pushed in) Doped separate cloth surround. Looks like a pro job

I'm wondering if it might be a factory or JBL dealer job because it has the original D130 serial number 51644
and then stamped into the metal right above the original serial number it has a new one 16499
Any idears?

No insight into this??

[Toxophilite]

That's what i was thinking. K series.the rest of my thoughts on the matter were pure speculation and casual interest.
I realize that nothing is really definitive but bits and pieces of knowledge can sometimes provide a clearer picture
I have no problem with the date stamp idea, why not

Does everybody have a computer in their pocket these days?? yikes! Mine would never fit in my pocket!

I dont' know this edgewound fellow except by forum reputation, but i would be very interested to hear any insight he may have to offer. The speaker works well and certainly sounds like a bass speaker compared to a D130

Just a phone call or email away and well worth the effort:

Its a legit conversion so to say. The d130 and the d and k 140 where pretty much the same frame and magnet. Some cosmetic differences from the d to k but that was it. The only issue is very old d130's had a much tighter magnet gap. Now I couldn't tell you if a k140 kit would fit in one of these or not though. I also can't tell you if that's a jbl cone either. I'm no where near as experienced as others on here. I do know that if you need an opinion on a cone to see if its jbl then post a photo of any hand written writing on the back of the cone.

Wow!!! I stumbled across this piece of JBL related translation genius in one of my searches
Sheer Poetry!

I kind of thought it was factory because who else would bother (or even know what size number would be probable) giving it a new serial number when it became a different speaker??
Anyway here's a picture of the only writing on the back of the cone
It clearly is a bass speaker now(sounds like one compared to the other D130 I have)
And the recone job looks really good

Ya to be honest that seems a little peculiar. I've never seen that. But I'm no jbl expert. Because to be honest using character punches on cast iron is a bad idea. Its very brittle and using punches on it is just asking for it to crack in half. It breaks like glass. But I wouldn't worry about it unless you plan to take apart the magnet.
I just don't see jbl going to the trouble plus they didn't punch the metal. They used embossed labels. But as I've said I'm no expert.

The numbers aren't in cast iron
With a sharp die stamp, the force to impress those numbers would be next to nothing
You could practically do it with the palm of your hand
Nothing close to cracking a magnet
Ever wonder why they're almost always flawed or "F'd" up in someway? (the foilcals on the backs of those big old Signature series woofers?)

Thanks very much!
I dropped him an email, with a couple photos
I haven't heard back but maybe sending the photos wasn't the best idea on an introductory email
I might've automatically been screened into a junk folder!
Probably a busy man too

Good Morning, Tox,

Ken, at Upland Loudspeaker, is a very honest, and exceedingly capable JBL serviceman! He's done work for me quite a few times, and his work is absolutely impeccable!! I've recommended him to some good friends, and they, too, had the same excellent results. If you left him a message, he WILL get back to you. But, he also had a full-time "day job", in addition to his fantastic work on our JBL's. So, please be patient, and you will be rewarded. He is most certainly "worth waiting for", when it comes to things JBL!!! Take care, and God Bless!

Every Good Wish,
Doc

P.S. I, too, have a fairly old D130, and am probably going to take it to Ken, and let him upgrade it, so I can use it for something fun!

Yes it's just the aluminum foil decal, not into the magnet.

I don't know anything about JBL factory or authorized repair shop procedures
I just couldn't see why anyone other than the factory or an authropized repair person would bother to put a new serial number on it
It clearly has been make into a different type of JBL speaker, Why would a home recone person or miscellaneous repair person bother??
It seems like a poor if not next to useless ruse.
It has the original number, it's not an attempt to obliterate or hide what it was
I guess it could be a number for a company that used the speaker but even that seems implausible

Any JBL employees out there that might know?

And how does one identify a proper JBL K recone kit?

[Toxophilite]

In case anyone is interested (I sure was)
Here is what Mr. Haerr told me about the D130/K140 I have

"I guess your question has to do with just what is this beast?

You're correct. It's a D130 reconed with a K140 kit. It's now a bass speaker, the K140. It looks to me like the the new stamped serial number could be after possibly the factory remachining the gap to .057" to fit the new cone assembly, and bring the gap to current spec. The original D130 was a narrower gap or .053". "


Very nice man and it was nice to get my thoughts on this confirmed!

[NickH]

I would tend to agree with you. Is the k the only writing on the back of the cone? If that's it then I doubt its a jbl cone kit. There usually a grease pencil date and then a stenciled number which I believe is usually part part number on the back of the cone.


If there's anything like that take a picture of it and post it.


Sorry I can't be of more help.

Found the number, it was hiding!! White stenciled number 52254 and some white grease penciled things; there's a K in another place there's a fancy looking R and a 2, and a 5 in yellow pencil
