This JBL D140F, Pro Parts reproduction recone kit is absolutely the finest recone kit for the JBL D140F available anywhere. This is a one piece, preassembled, drop-in kit. It is complete and comes with every thing you need to recone this speaker yourself. Very easy to install. Click here to see.

If you have a JBL D140F, 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 D-140Fs.

Voice Coil:
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 The voice coil is flat wire wound / edge wound, with copper wire, wound on a Kapton former. The coil has the correct polarity and DCR of 5.6. Yes this is the correct DCR for an 8 ohm JBL D140F 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 D140F 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 D140F 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 D140F recone kit is pre-assembled using our custom manufactured jig, created exclusively for this recone kit. Using this jig to assemble the D140F 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.

Dust Cap:
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, similar to 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

Centering Shim:
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. Click here for step-by-step, easy to follow instructions for installing our Pro Parts DIY recone kits.
