Is it cost effective to have a 45 year old JBL D130 reconed?

if its not a D130F i would not do it for use in a guitar amp. the F series has a wider gap in the voice coil.
the original D130 is more of a PA/stereo speaker. yes you can use it for instruments, but it was not designed for that. harvey gerst is the engineer who redesigned the 130 for instruments. he had JBL open up the gap and add an accordian edge with damping. this helped stop the problem with the D130 of twisting the cone and shorting out the voice coil in the narrow gap when pushed hard in guitar/bass amps.
if you are going to use the speaker for stereo use then recone it. i dont think you would ever find a REAL JBL cone kit for it, so what ever you find will never make it an original JBL D130, but it still might be usuable. |

I would do it in a heartbeat, there are several places around that can do that for you for much less than the cost of a speaker of the same quality.

Is it worth it? Well, that depends......
a 45-year old JBL D-130 most likely needs to be regaussed; Alnico magnets reputedly lose 1% of their power per year; perhaps more if pushed hard a lot.
That's approximately $35; a good recone KIT is about $100. So, you're up to $135 plus shipping costs if you do it yourself; Reconing services charge $200-$265 to do the whole job.
If you REALLY want that JBL sound, there's nothing else---you can't buy a new one.
The new Telonics are supposed to be the closest thing, but note that they are 3db less sensitive than the original JBLs; thus requiring twice the power for the same SPL. They are approximately $200 (I think). |

Bob Crooks designed the original Standel amps to be used with the original D130. Then,Dick Dale, who was getting a lot of attention, kept blowing the D130...
"Leo Fender kept giving Dale amps and Dale kept blowing them up! Till one night Leo and his right hand man Freddy T. (Freddie Tavares) went down to the Rendezvous Ballroom on the Balboa Peninsula in Balboa, California and stood in the middle of four thousand screaming and dancing Dick Dale fans, and said to Freddy, I now know what Dick Dale is trying to tell me. They went to JBLJames B. Lansing loudspeaker company and explained that they wanted a fifteen inch loudspeaker built to their specifications. The unit became famous as the 15" JBL D130F model. It made the complete package for Dale to play through and was named the Single Showman Amp. When Dale plugged his Fender Stratocaster guitar into the new Showman Amp and loudspeaker cabinet, Dale became the first person on earth to jump from the volume scale of a modest quiet guitar player (on a scale of 4) to blasting up through the volume scale to TEN! That is when Dale became the "Father of Heavy Metal" as quoted from Guitar Player magazine. Dale broke through the electronic barrier limitations of that era!"
Bob Crooks gets the "new" D130F and it doesn't sound the same as the original D130...and he became very unhappy. |
