~1969 JBL D140F Grey

Offered for sale;

Used JBL D140F speaker, serial number 21751, cone code 29675, grey frame in good condition.

These speakers, originally developed in the mid-‘60s sound great.

Some JBL trivia from D140F designer, Harvey Gerst:

“The D stood for a metal dome and the A and B were for woofers of different impedances. I don't remember if we made a 131A. We also made a D123 (full range pancake 12" speaker) and the D208 and D216 (both 8" speakers but with 8- and 16-ohm voice coils).

“Fender was buying D130s for use in their Dual Showman systems, but they were experiencing problems in surrounds drying out from outdoor use, and burnouts from improper mounting techniques. I wrote a memo to the president of JBL, outlining a plan to let me design a series of speakers made specifically for musical use and he agreed. My plan called for modifications to the D130 and D131, plus an all new bass 15" speaker, and a new 10" speaker.

“Since Fender was our largest purchaser, I did not want the headache of trying to re-introduce a whole new series so I kept the D130 name for the 15" and simply added an F (yes, the "F" is for Fender - don't know why to this day I did that, but I did). Since I was making up new model numbers, I decided where possible to keep it simple, so the 12" (originally the D131) became the D120F, and the new 10" became the D110F.

“That left the new bass speaker. I didn't want to leave it in the 13x range because it was different and the 150 was already being used by our theater woofer. The 140 was not being used, so I named the new bass speaker the D140F.” Harvey Gerst

Great vintage JBL at a nice price!
