The D departed from common loudspeaker design in a number of important ways. First, the frame was cast, instead of stamped, for increased durability. It was one of the first loudspeakers to use Alnico magnets, making the D highly efficient and capable of higher output. The 4-inch diameter voice coil was much larger than other models and edge-wound with rectangular ribbon wire, which provided superior performance. D also featured a very shallow curvilinear cone and 4-inch center dome for extended high-frequency response. All of these innovations resulted in a loudspeaker that was 10 dB louder than typical speakers and capable of handling significantly more power. D quickly became the standard for a number of applications, including early s hi-fi systems. Guitarists began to swap out their stock Fender speakers for JBL Ds to achieve louder, cleaner tones.

Read the current issue of VG. Often, the lack of prolificity had little to do with their theoretical success as designs and more to do with timing, a slight misjudgment of the market, or both. Such is the case with the brownface Vibrasonic. All that aside, though, it was hugely historic, and is still an extremely desirable combo as it stood three years later in the 6GA format. The new covering and forward-mounted controls might be its most talked-about design features, but the Vibrasonic was also the first Fender amp with solidstate diode rectification, the first with a JBL speaker as standard equipment, and the first Fender above 20 watts with built-in tremolo.

Mic has graciously granted permission to post the stuff on the JT30 page on the off chance that it might be useful in the context of Blues Harmonica. Mic is not responsible for the content, just the collection. It’s supposedly a speaker designed for keyboards, but I hear one boutique amp maker uses it on guitar amps. What I’m particularly interested in is it’s efficiency relative to the V30, and how much low-end it has in an open-back cabinet more than a V30?
Hi Tremolux, I like it more than the V As you mentioned, GT uses it, so you may be able to get a listen.
The serial numbers are.. time era, JBL did not put a user friendly dating number on those speakers. – Hi, How do you tell the date of a JBL DF.

Not sure if it’s really a keyboard speaker, as it’s got all the trademark Celestion bumps and rolloffs. That may have been started due to the ‘K’ terminology. Celestion says it has ‘more bass’ than the V30, but I don’t take their literature very seriously.
I’ve even called Celestion USA to try to find out about some of their speakers Anyway, my own opinion of the K is that it has less of the brash, forward midrange bump of the V This may make it seem as if it has more bass, but that’s not necessarily so. The most emphasized effect is the upward tilt at the top end. Imparts a very chimey character to the treble end.
Not overbearing unless your amp is overly bright to begin with. Not quite as much Celestion ‘bark’ as the V30, but that’s just fine with me.
