Jbl Serial Number

May 10, 2018 - *Serial number Some of our products do not have serial numbers. In this case, enter the date code from the product box or the back of the unit. Feb 02, 2017  Genuine JBL Products will have a serial number that can be successfully registered. Also you can visit a nearby JBL Service Centre and get your product checked. They will use the barcode of your product to see if its Genuine or yet another fake.

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. 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.
