Here is a matched pair of vintage JBL D130 15", 16 Ohm speakers which came out of a pair of C51 Apollo speakers which I am parting out. Very close consecutive numbers of 70922, 70928. They are in excellent cosmetic condition and have the original JBL cork gaskets for around the perimeter. Both speakers have the original cones but one of them has a very old tear which was repaired years ago. It will need a new repair or a re-cone to be usable. They measure 6.4 & 6.5 ohms on my DVM with no load. An excellent addition to anyones collection. Money back guarantee you will not be disappointed.

L65 pair with dated bill of sale listed in ebay auction.
These were originally purchased in the UK.
Bill of sale dated September 8th, 1978.

L65 serial number 69252A and 69817A

from auction description:
Beautiful pair of JBL L-65a Speakers with Original boxes, Tags, Manual, Paperwork, Warranty card and Bill of Sale, wow!
These are in amazing condition and need nothing. I am the second owner having bought them three years ago in Utah. I drove 400 miles one way so that they would not be shipped. The woofers have been refoamed within the last few years, the other drivers are perfect also! One woofer has a slight discoloration consisting of some soft white markings which is purely superficial. I will gladly send close up photographs of each driver if requested! The foam is perfect as it should be having been refoamed a few years ago. There are a few small nicks in the wood and something was dropped on the edge of the glass before I acquired them a few years ago. This created a noticible glass ding along the front edge about the size of a quarter. I decided to ignore this due to the fact the glass is scratch free overall and the foam and JBL tags are still on the underside which is cool. I would suggest you not worry about this flaw either. These speakers also come with 1.5 inch gold grounding spikes. This has been my personal set of speakers for the last three years and they are wonderful. I am choosing to let them go to a collector who does not move as often as I do so they stay in pristine shape. They are made of American walnut and truly are works of art.
These speakers consist of three drivers, one is the famous horn loaded ring radiator 077 tweeter with its amazing dispersion, the 5" LE5-5 midrange, and the JBL 12" 126A woofers. This is where I customized these speakers a bit. The woofer that technically goes with the L-65a is the JBL 122a woofer, however after some research I choose the earlier version woofer from the earlier version of this speaker called the Jubals. This tightened the bass a bit to my ears. Now, the 126a woofers are more expensive and rarer than the 122a woofers, so if you choose to go with the 122a's that would be your choice in the future. Listen to them first with the 126a's and then decide. I have used these daily with my vintage Sansui G -901DB and they sound great! They are gently used speakers and have never been pushed to even moderate levels of sound since I have owned them. The sound is perfect and equal out of both speakers.
These speakers where bought as a pair and you will have the entire history of these fine speakers in the paperwork. The seriel numbers are 69817 a and 69252 a.

Q: Can you please tell me the date on the bill of sale? Thanks and good luck with your auction! Glen Oct-04-07
A: The date of sale was September 8th, 1978. These where purchased in Upper Heyford, England. Good Luck!

Are you wanting Altec serial numbers as well?

I also have some Altec catalogs, price sheets, and the spec sheet for the Altec Valencia which are not in the library.

Hi Larry,
welcome to the forum.

we started also to collect Altec numbers, but there wasn't that much feedback (we collected about 6 numbers in 2 years) so we gave it up.
The JBL Registry now counts about 7000 items.

To your Altec catalogs:

please take a look at this :

http://www.audioheritage.org/html/interact/scans.htm

so you can send the scans to our webhost Don.

thanks

with the collection of data is it now possible to
get an approximate date on the manufacture of a 375 driver? for example, the one seen in my avatar?

[diamondsouled]

Thanks for the info HP. I'll get the catalogs scanned and submit them.

Hi I have a jbl d-130 with serial number 511169 I was looking on ebay and found another d-130 with the same number. Is there a mistake? did jbl make speakers with the same serial numbers on them?

hi jbl inspired,

no, this is no mistake.
from end 40s to beginning of 1956, JBL had a special numbering system.
This was dechifred by our member Glen.
It may be a time where they do not built that large number of drivers a year.
this is the 6 digit code.
the 511 stand for November 1955 and the 169 is the same on all D 130 from this time. This means, that there will be between 50 and 100 pcs with the same number, built in the same month of the year.
Later (march 1956) they started with a rising numbering system, mostly beginning with 10.
That's what we found out till now.......let's see...........

PS: the registry counter from today shows 7031 items, thanks for all the help.

[Harkness]

yes harkness,

HP

ahh! wonderful, thanks Hofmannhp!

the other 375 that came in my system is serial 2885. is that from much later? i guess it is safe to assume the system was built at the time of the latest component. i don't know the serials on my 150-4C's but i could look for the N400 serials.

is there a place on the site to look them up, or do you have the database?

thanks again!

Hi Harkness,

the driver with 2885 is from beginning 1958.

there is a 375 with SN 2982, built in a Paragon. This paragon is dated saled 1959. Maybe that a Paragon needs a longer time to be saled, so the driver was built in the Paragon in 1958, but sold in 1959.

No , the list is not posted in the forum. But if you need something, let me know and I will send it to you.

many thanks, again, HP.

i believe my speakers would have been a custom order, as it was the 375/15-4C/N400 combination, but in a Harkness cabinet, with the 375's mounted in the horn mouth driving the curved H5041 horn. it seems it is likely my system dates from 1958 based on the age of the newer 375.

i will check the crossover serial numbers and see if they corroborate this hypothesis. unfortunately i am not able to open up the cabinets to look at the 150-4C serials any time soon. however, i will take note of them should the chance arrive.
