I've done both, from experience the smaller drivers are easy to refoam, the bigger harder to centre. A long as you can access the crossover and remove without much trouble, they're pretty easy to do. What are the speakers in question?

If you want a company to do them for you, these folks have done some warranty work for me previously:

Some old jbl with 10 inch driver.
I’ve read about centeri g with a soecific test tone when glueing.

It always looks so simple on youtube, but i have doubts.

Mike Powell in Bolton has done a few for me, and an excellent job too.

If you can take the drivers out (but maybe they already are ...) then I think the postal service should work. I once asked the Wembley people if they could do a repair job, and they said no problem if I took the drivers out of the cabinet. In the end I found replacement drivers. Worth giving them a phone call, anyway - I’ve heard they’re very good.

Some old JBL drivers really are superbly 'world class' and for myself, I'd recommend a professional to do this work (I'm a coward with classic stuff like this possibly is, but then JBL also made bog standard drivers too).

Living on the Suffolk coast, I had Wembley Loudspeakers re-foam the old 6" Elac bass drivers in my IMF Compact mk1's. I packed and sent them UPS 24 hour (via Interparcel) and they came back a few days later superbly packed and re-foamed. The dust caps had been replaced and re-doped (the original had the entire front face in a ripply-crackle type doping) but as they only go up to the lower midrange, any change in the dust cap wouldn't matter at all. Lovely to have them working and they're amazing for an early 70's box.. Cost was around a hundred quid, which was a bit mad bearing in mind the speakers, but hopefully not hugely more for classic JBL drivers that would cost hundreds each now if new, may be worth considering.

Obviously sending them would mean careful packing to save impacts knocking magnets off etc., but I'm sure any decent professional could advise on packing for safe transit.

Well....a bit of a dilema.

A pair of jbl L26 arrived today.
I've wanted some for ages.

I had intended to refoam myself possibly.
But having got thrm they are in fantastic condition.
In original boxes and pacaging.
Evrn the grilles were in original plastic rwrapiing.
45 years old.

I think they deserve better than my grubby mits all over them.

I think the crussuver is very simple.

So i'm definately leaning towards them being refoamed and recapped by an exiert.

If they look good, why refoam them?

Cosmeically excellent.
Someone looked after these.

The foams have cracks and need replacing.
Due to being from te 70# i would also like to recap.
I think there is only one cap.

If you could wait until after the Hifiwigwam 2019 show or bring the bass unit to the show, I can undertake the reforming of the L26 bass units please take a look at the link below:-

I found the crossover capacitor to measure within spec with my L40's the biggest problem is the "L-Pad" control and corrosion.

The JBL L26 speakers are pretty nice. They were the middle model in the 'Decade' series L16/L26/L36 trio of compacts. They used a derivative of the LE20 cone tweeter if I recall. I think I still have the original brochure somewhere. They're certainly well worth having a top class refoaming on the cones.
