Hey everybody!
I just purchased this speaker. The seller has great reviews... fingers crossed.

Assuming all goes well, I was wondering what my options are for the best Jerry tone?
Dope? Re-cone? Will dope affect tone? The seller seems to not have faith in the cone lasting.
I'll probably play through it first.... just wondering about longevity, really.
Thanks- Jim

This is new territory for me. Why the E120 kit rather than the K?

+1 for Spiral. I have several Ks and Es Alan has done and they are excellent.

This is just my understanding and I am no speaker tech but the aftermarket kits are available for the D or the E. Ks get the E120 kit as they are interchangeable but obviously you have the alnico magnet. So your D131 would have the E120 kit and make it basically a K.

Congrats on grabbing the D131...

I have to chime in here and suggest you contact Ken Haerr at Upland Speaker Service.

He makes his own cones specific to each and every model JBL and is regarded as the last word on all things JBL.

The original D131 has a narrower voice coil gap than the D120F. The current aftermarket kit is a much different animal. (Rolled cloth surround v. Paper, etc...) It is designed as an all purpose JBL MI series replacement but specifically only the D120F, E and K series benefit from it. Furthermore, use of the current aftermarket kit in a D131 will guarantee that with any substantial power it will develop a voice coil rub sooner rather than later.

So I have a k130 4ohm that needs a recone. The speaker works but it seems tired. With it being not as peculiar as the D131, will I be totally satisfied going with sprial or do I still send it out to Ken? It’s a huge price difference and I’m sure his work is next to none but man we’re talking $300+ vs $120 if I’m not mistaken

Thx TeeJay, my only concern was, would it to still hold its JBL characteristic after the recone. I already emailed Alan and will double boxit over there soon.

Ken is the only one making accurate model specific OEM style JBL recone kits...with that said, yeah, he is twice as much as all the rest but you get what you pay for. As far as K130's, he recently did a K130 and D130 for me as I was restoring a rare 76' Boogie Mark I 15". I went with the K for that amp because it had the slightly higher power handling than the D.

I don't know of Spiral Reconing services. They look to be good and have quite a variety of speakers they do. For that price he is definitely using SS or ProSound aftermarket kits. The last OEM JBL K120 or K130 kits were sucked up by A Brown Sound. They were selling them for $375.00 each...

Go on the Lansing Heritage Forum and follow Ken's technical input and qualifications...He goes by "Edgewound".

I still recommend using him. It's worth the bread. It is part of respecting the higher level of skill and that audiophile hi-fi vibe. It's an artform and he gets it.

I completely agree in the ‘you get what you pay for camp’
I use this tactic a lot of the time and while it does add $$$ up, the end product usually does prevail. I’m still gonna think about it for a bit. Thanks for all the info.

I used Ken at Upland (Edgewound) for some K-120s I came by - expensive, yes. Worth it - YES!

I exchanged a few emails with Ken last night. I think I will go that route. Yes expensive but from reading up on his process, it’s like literally getting a brand new JBL.
