This is what Harvey Gerst, JBL designer says : "There was 2 ( 12" ) models. The F model has a bigger voice coil gap to allow for slop in baffle flatness, but it takes an efficiency hit." was a "D120".The closest relative to the D120F was the 12-inch D131 full-range hi-fi speaker whose frame and magnet structure was adapted for use as a musical instrument loudspeaker.However, in the various meanderings which this thread has taken, it seems like we've neglected to address your original question -- sorry about that.The original JBL's as developed into musical instrument speakers for Fender in the early '60s had gray frames and magnet covers, with the foil-cal on the rear of the magnet cover in a gold/silver format. The orange frames are JBL D120F's in the 12" speakers, and JBL D130F's in the 15" series. The D120F is orange and was the one Fender had made for them.
The frame and magnet are the standard gray but the foil-cal is in blue/silver, with the Vox logo printed in black (I have no idea what Vox amp used this driver).HTH Arjay_________________"Here's why reliability is job one: A great sounding amp that breaks down goes from being a favorite piece of gear to a useless piece of crap in less time than it takes to read this sentence." -- BRUCE ZINKYArjay, Very informative. One thing that I've found amongst the hodgepodge of JBL's in my stash, the 12-inchers have a fairly consistent tone as do the 15-inchers. As long as you place them into the same cabs for comparison & the cones/VC's are in good working order. They sound like somebody torturing a smoke detector with an ice pick. A capitol federal statute with a mandatory death penalty.That's something I can't say about some other speaker brands. Arjay_________________"Here's why reliability is job one: A great sounding amp that breaks down goes from being a favorite piece of gear to a useless piece of crap in less time than it takes to read this sentence." -- BRUCE ZINKYGreetings -I just stumbled onto this site this evening, and felt compelled to pipe in because there is so much misinformation to clear up.Then in '69 the entire line of speakers produced for Fender received a total cosmetic re-make: The frame color was changed to orange and the magnet cover was painted black (the foil-cal remained in orange/silver with the Fender logo slightly enlarged).The above applies to the 12-inch and 15-inch speakers -- the 10's started out as an all-black speaker, changing to the orange/black scheme around 1970.
As commonly known, the D120F was created because Fender originally used the D131, which was a failure for the following reasons. I do find the basket flexing issue a bit hard to swallow, but that's what I was told. The new 12" speaker was developed at that time for Fender by means of increasing the gap width, and switching to the linen surround.
