If you have a JBL K140, and you want the classic sound that it had when it was
new, then you need to recone your speaker with this kit. This kit features a cloth surround and ribbed cone, just like the original K-140s.
We have done a lot of research on this kit. We know you want the very best for
your vintage speaker. We started with the voice coil, custom made for
SoundSpeakerRepair.com. The voice coil is flat wire wound / edge wound, with
aluminum wire, wound on a Nomex former. The venting holes have been placed in
exactly the same location as the original coil. The coil has the correct
polarity and DCR of 5.6. Yes this is the correct DCR for an 8 ohm JBL K140 coil.
The coil weighs 5 grams,
again the same as the original coil.
The coil was made to the exact specifications of the original JBL K140 voice coil
except for the former height. We increased the former height 0.0394 of an inch to
accommodate the modern spider.
The original JBL K140 kit assembly (cone over coil, spider over
cone) was difficult and unpractical way of assembling. Also, the original spider is no longer in
production. JBL has moved to a new, now standard, assembly method (spider over coil,
cone over spider). We have also adopted this method and use the modern JBL
spider. This new spider is 0.0394 of an inch taller at the cone mounting point. This is why we made the
coil 0.0394 of an inch taller to accommodate for the modern spider.
This K140 recone kit is pre-assembled using our custom
manufactured jig, created exclusively for this recone kit. Using this jig to assemble the K140 recone
kits ensures the spider and cone are set to the exact proper depth to put
the voice coil in dead center to the magnets top plate every time, giving you
the most efficient speaker possible after reconing. We use only top grade
cyanoacrylate adhesive for the coil to spider joint and spider to cone joint
resulting in a superior light weight bound that will hold up with years of use.
We use an aftermarket aluminum dust cap for this kit. The kit is assembled
in such a way as to accept an original JBL aluminum dust cap if you choose to use
one. Original dust caps can be found from time to time on the internet.
The cork gaskets we use are the modern rubberized cork gaskets,
the gaskets used by JBL today.
We include a 1 oz. tube of glue with this kit for gluing
the surround and spider to the frame. This is the same Moyen RS-3087 adhesive that is
shipped with original JBL recone kits and re-packaged for
Voice coil centering shims are included. The shims are used
to keep the voice coil centered in the voice coil gap while the recone kit is
fitted to the speaker
frame. The shims are removed after the adhesive has dried.
Printed instructions are included with the kit, and can also be view online.
