Re-cone E145 OEM kit Vs. Aftermarket

[mbeards]

Hi Everyone,

Unfortunately I have an E145 with a mint OEM JBL cone in it that has a lose voice coil and voice coil rub.
I am wondering if anyone has had thier E145 re-coned or done it themselves with an aftermarket or OEM kit.

OEMs are extremely hard to come buy so I fear an aftermarket is the only option (Unless a member as a stash of OEMs )

I am skeptical of the aftermarket kits since the E145 is a rare beast. Its moving assembly is lighter than that of the E140 as it was Hi-Fi woofer and had a smooth cone.

The only aftermarket kit I can find is here:

Note here that the voice coil is not vented which leads me to believe they have not done thier research and this kit is a mixture of parts.

These guys have much nicer kits IMO but none for the E145's.

Please help!

A skilled repairguy should be able to fix your voicecoil.

Oh really? how do they get access to the voice coil to get it re-glued? Would it be a good permeant fix?

The cone and the spider can be removed and if you are lucky there are no loose turns on the voice coil. Then the bobin (if that is the problem) can be reglued to the cone. The VC rubbing could be just dirt in the gap.

It will not be cheap though.

I live in Europe and had my E145 reconed with original parts last year. I think it was about 280 euro, say 350 US dollar. I was told it was their last kit then, but I don't know if it was the last on the planet, or just the last in their warehouse...

check and see if the epoxy bond between the voice coil former / spider / cone is broken - this can be viewed from the side and it's where the spider meets the cone. On some of the 145's and other MI kits I've seen this and it can be fixed by a competent tech without removing that cone. The thin paper cones are VERY hard to remove intact unless you have a lot of patience and enjoy MEK headaches.

On the other hand, the foam vent filter on the magnet ( under the dustcap ) often crumbles with age and can mimic the sounds you're hearing..might as well just cut the dust cap off CAREFULLY and take a look. You can also inspect / clean the gap and would need to put shims in the gap anyways to center should epoxying be required.
