JBL K120 cloth surround recone kit:
This JBL K120, 8 ohm reproduction recone kit is absolutely the finest recone kit for the JBL K120 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 K120, and you want the classic sound that it had when it was new, then you need to recone your speaker with this kit.

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 venting holes have been placed in exactly the same location as the original coil.

The original JBL K120 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.

The cone shape is curve linear with a cloth surround. The cone is custom made for us to fit the new height of the voice coil and spider assembly. The cone weighs the correct 20 grams. Unfortunately, the vintage cone pulp formula is no longer available. The modern pulp is very close in consistency, resulting in an excellent cone in weight, strength and resonant frequency. If we could find original cones, we would use them. Original cones are not available.

This K120 recone kit is pre-assembled using our custom manufactured jig, created exclusively for this recone kit. Using this jig to assemble the K130 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 bond 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:
A voice coil centering shim is included. The shim is used to keep the voice coil centered in the voice coil gap while the recone kit is fitted to the speaker frame. The shim is 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.

Guarantee and Warranty:
And on top of all this, each kit comes with a 100% satisfaction guarantee and a 2 year warranty. Click here for full guarantee and warranty details.

5 out of 55 out of 55 out of 55 out of 55 out of 5 K120 Rebuilt, 2.4.2012
Reviewer: John Gomes (Oakland, CA)

I was bummed when I found the K120 I bought was dead. I have had two rebuilt by a really good company using Hemp Cones and it cost a lot, I mean a lot! I couldn't pay for another so I looked on ebay and around the internet and decided to try it myself from the kit here a SSR. I am pretty competent with home repairs and figured I could do this if others had. The kit is simple and instruction pretty good. I would like the SSR folks to make a youtube video themselves because there a few details I think could be interpreted one way or the other. Like how clean is clean enough? How do I really know what to do with a rusty gap? But al in all I did it and the results are great! Speaker sounds a bit better to me with this kit than the hemp cone. I asked for a paper dome because I don't like the aluminum domes. Too bright or shrill. SSR had no problem including it instead of the aluminum. I will buy another repair kit in the future for sure!

All I can say is everything needed is included, and it is just like the original. Prompt service and faster than expected delivery.
