If you do not see a sticker look for engraved numbers on the back surface of the speaker or turn the speaker over and inspect for numbers. The first three digits indicate the maker of the speakers.

Depending on when the speakers were made, the maker may be Altec Lansing or Harman Kardon, both of which have owned JBL at one point.

Looking to sell onkyo receiver that comes with magnepan mmg speakers (pair) and dbox powered subwoofer...i also have another mmg but it does not have any cloth and not stand (was used as a centre speaker)...

vintage sony ss-w three way speakers in good shape..grills don't have any real blemishes, but should be stretched and reglued...i don't want to do it wrong and someone already tried to staple them...

JBL is short for James Bullough Lansing, who founded the company.

There are some easy ways to find out when your vintage Fender was manufactured.

Up until the end of the blackface era (1967), all amps left the factory with a tube chart that had a two letter date code stamped on it.

The tube chart date code works like this: the first letter indicates the year and the second letter indicates the month.

Look at the digits after the week to see the day and possibly the hour the speakers were made.

While this is not a requirement for manufacturers, some include this information.
