this is the right question for Giskard.
I can imagine, that they (JBL) have a detailed list with the numbers (for guarantee problems) and are able to find out the fabrication year.
What should the numbers be for, if not for this???

Please help us save more info about the vintage systems. Let us register your speakers and drivers.
I know for a fact that this is not the case. The Northridge earthquake back in 1993 destroyed the majority of JBL's production records. Therefore, they have lost the ability to correlate serial numbers with year of production.

I have a D130 serial # 82039 that I'd like to hear any guesses as to its age.
Well, since you're asking for guesses...Originally Posted by sluggo47
I have seen D130 serial numbers as high as 90661 so I think your 82039 serial number would place it kind of towards the end of the line in the mid to late 1960s.
Just a guess until we get more info in the serial number registry thread

Hi Sluggo,Originally Posted by sluggo47
the JBL-Registry says:
No. 26536----> 1957
No. 40812----> 1960
highest No. in the Registry: 212167 -----> ??
The D130 was first built in 1948 and the last in 1977 (unconfirmed)
Glen maybe right with his assumption mid to late 60's

Thanks for the warm welcome HP. I could use a little help identifying the cabinets.they're rear projection bass reflection, The only identification I have on them is a sticker inside each cabinet that reads.....
To adjust R4 cabinet response space this plate from bottom opening in cabinet with the exact number and size of spacer block on each side as listed below. Suggested settings found suitable for popular speakers shown (these setttings do not necessarily correspond with resonant frequency as given by manufacturer).
20 cps one 1/2" spacer
