Shouldn't make any difference as for as sound goes. Weather 100 speakers were built in between them are they came off the line next to each other.
Carvin Amp Serial Number Lookup. 8, the Altec- Lansing speakers were dropped, in favor of the. British- made Celestion speakers. Carvin's Magna. Lab speakers were. Celestions could be ordered in the concert stack. JBL's could be ordered in combo amps. More changes. Gauss speakers were added in.
I remember buying my L100a's new around 1978. I read an advertisement in the Saturday morning newspaper that Pacific Stereo had a handful on sale for that day only.
I rushed to the store and the salesman told me to grab any two and then pick the color of the grilles and grab one of those boxes. As a super excited 19 year old I didn't stop to think about serial numbers. I just picked two, paid and got the hell out of there. Smoked a fatty on the way home and enjoyed my new JBL's later on.
As you can see 19 numbers from each other. Close, but no cigar.
That is very far apart so not big nit pick JBL change vendors for caps and l-pads too If driver types match should be ok but that far apart veneer almost always not very good match Tweeter change 3 times on L100 from start to finish look same but not Those number so far apart woofer might not be the same either look same but not same polarity or cab wire Back in day so many L100 get sold guy at store just grab box off shelf not pay attention to number so 10 20 even 100 apart normal but thousands apart? Grain match JBL fairly rare so who care if 10 20 apart but 100,000 is lot! Not even sound right! That pair of speakers put together paired up by somebody or came from PX or JBL warehouse direct where number that far apart could both be in same batch inventory No pair have number that far apart for normal reason or from little stereo store in 1970s unless lost in attic and L100 not all same even late type I almost will bet JBL never had 100,000 pair in warehouse at same time Maybe someone do cap job and buy used foilcal off auction or put drivers in different box? It seems like it wouldn't be too difficult to investigate further. Remove and compare the individual drivers against the ones from the other speaker (Woofer, Mid, Tweeter), including visual comparison as well as comparison of any model numbers printed directly on the drivers.
Compare the empty cabinets to see if there are any differences in terms of the port, the stuffing, where the crossover is mounted, etc. Compare the crossover in each speaker to see if they have the same layout and identical components, etc. If no differences are found, then I really cannot see this as a big deal, and don't see where any perceived difference in sound would be coming from.

Click to expand.Believe what want to believe unless seller find unsophisticated collector will have hard time realizing top dollar for mismatch pair and 100,000 units apart is BIG mismatch for JBL L100 Explain one more time different vendors for caps for pots for wire and different woofers MAIN thing and 123-? 12' varants all sound AND MEASURE different even Aquaplas on cones different in different batches over long time Woofer polarity can be different too and numbers on JBL drivers not always tell truth if ever reconed Average person might not hear but many people will and LOTS of Frankenspeakers out there in JBL world thanks to cannibals Have nice night!; - ) JJ. Or it could be that JBL went to a different s/n scheme at some point and these 2 specimens might not be that far apart.
For instance sometimes, particularly with firearms, s/n,s have dates of manufacture coded into them which can throw chronological order out of whack. It's not at all a given that all s/n's are in sequential order or even model specific and any buyer that places that much stock in the s/n's is probably looking for anything to beat down the price IMHO. With all respect to JJ, no one has stepped forward with knowledge specific to how the s/n's work in the case of the L100 or how one derives a DOM so no conclusions should be jumped to until then.
Click to expand.To whatever extent any of that actually applies to the speakers in this case, all differences could be revealed via inspection and measurement. 100,000 model numbers in and of itself doesn't mean much without context. We don't know how far apart, in terms of calendar dates, that these speakers are from each other. It's possible that we are talking about less than a 12 month difference. Everything in your post is pure speculation, yet you seem pretty confident in your conclusion. I think it would be better to stick to the facts here, which would require further investigation from the OP (if OP is even still following this thread).
JBL did make many modifications to the L100, but they also made major obvious changes such as the layout of the drivers in the front between many of those different versions. The OP said that they are visually identical. That to me would imply that they really aren't that far apart (in practice, not theory). The difference in model numbers could be indicative of potential differences, but it's not a given nor a guarantee.

Anybody know of any current information on dating JBL speakers from the early years up through about 1970? Cone number nomenclature, serial numbers, any links with updates or personal knowledge will do. Anybody know what model and what year Fender started utilizing the JBL script badge on the front grillecloth of JBL installed amplifiers.
RussB Contributing Member. Connecticut a little out of tune Feb 16th, 2009 10:22 AM some interesting reading. 54-Strat USA Feb 16th, 2009 01:00 PM Wow, what a cool site. Gmein Out by Bakersfield Feb 16th, 2009 01:28 PM Thanks RussB, still cannot come up with anything definitive on this and have been researching this for years, we might just have to put out a thread for users to respond to with their JBL installed Fenders and supply the Year, Model and serial number of the speaker(s) and see what can be ascertained. I have seen many myself but I am perplexed as to how they were serialized. For instance I have seen D120F's from 1962 with later numbers numerically than from 1964, that is I have two amps that reflect this oddity, if it is an oddity.
![Serial Serial](http://a67.tinypic.com/b5ry2d.jpg)
I recently saw a 1967 that had earlier numbers than a 1964 and the number spread was like 12,000. I am curious as to their method, same with the codes on the cone paper. All my original cones from 62 to 64 have 21032 on the paper. For all the original contributing members, How many times has this been covered. I would like to go back and read.
Any input will be appreciated. Thanks Gmein, P.S.
Not finding too much out there on the net! Shobud-Twin L.A. No sir, I don't like it. Feb 16th, 2009 04:50 PM My understanding is that JBL D series cannot be dated by serial number. I think this has been confirmed by Harvey Gerst (who helped develop the line at JBL). BTW, Great speaker!
I have a pair in my '69 twin (has the badge) and one in my '69 princeton reverb. Plus I have a number of backups and a couple D130Fs as well. All greyframe original cone. I'm kind of obsessed. Jazzguy Contributing Member. Philly, B-3 Capitol don't dream it.be it Feb 16th, 2009 07:47 PM Shobud, I posted in the amp repair section about reconing a pair of grey D-110F's I just scored for use in a Vibrolux Reverb alum.
Dome or paper Have always used '60's brown/gold Jensen C10N's in my VR's and love 'em but am intrigued w/the idea of a pair of D110F's in there for some extra headroom. Ever use these 110s or just 120's?
RussB Contributing Member. Connecticut a little out of tune Feb 16th, 2009 08:09 PM Like Shobud-Twin says, there is no definitive dating info on the JBL's. Heck, it's tough to find a PRINTED chart on their power handling capacity or impedance. I have a D-130 that was labeled 16 ohms, but measured like an 8 ohm speaker (7.something resistance).
I've seen them labeled 16/8 ohm as well. Shobud-Twin L.A. No sir, I don't like it. Feb 16th, 2009 10:20 PM I don't have much experience with the 110s. Heard mostly good things though. The only pair I played was in a brown super, which wasn't a very good fit for them.
Oldog50 Contributing Member. near St. Louis Oh Baby, It's a big old goofy world Feb 21st, 2009 11:04 PM Jazzguy,my BFVR came with D110F's in it when I bought it,you had better like BRIGHT amps if your going to try it. I would definitely recomend the paper dust caps.
The VR's are relatively bright amps anyway. D110's with aluminum caps in one will damn near cut your head off. (This message was last edited by oldog50 at 12:05 AM, Feb 22nd, 2009) StevenEsqTwo Contributing Member USA Feb 22nd, 2009 10:46 AM Somehow I ended up with 4 D110Fs in one of my speaker buying binges. I tried them with everything Fender. Didn't like them one bit. Too clean, too bright and too heavy.
Gundry ohio Feb 28th, 2009 11:31 AM I bought a Kustom head and 3-15' ported tuck and roll cab. The output jack was diamond shape and said CTS but when I opened it up there were 3- 15' JBL grey basket 130-A's. All three are blown with large paper rips and I have contacted Orange County Speaker Repair and Ted Weber about reconing. I have been told that these can be made into D-130-F's. The cab and head are dated to 1966.give or take.just try to find quality info on early Kustom gear! Is it correct information that the difference of the D-120-F and the D-130-F is 12' to 15'? Mine are labled ' 130-A.16 OHM.306-482R.the paper stamp is 130-2XXXXX.
' I can not see the X's on the paper from my photos but could easily get them if it would help anyone. These speakers are HEAVY! I still can't decide if I should just buy 3 new speakers, recone with aftermarket parts, or recone with original JBL parts. The most expensive I think is the original part recone but I have been indoctrinated that the JBL D-120-F orange lable speaker is THE speaker for the Duane Allman tone quest. I get concered when I read the above posts complaining about unwanted brightness.
Did everyone give there speakers a good break in period or were they yanked soon due to poor tone? Is a D-120-F and a D-120-F orange lable the same speaker?
