Hello everybody,
after I got a tip from an owner of a studio in my hometown Hagen, Germany, I picked up a pair of 4435 from a warehouse. The speakers were used in the studio for 20 years and from there on stayed in the far corner in the dark. The foam of the 2234 are all rotten but the coils seem to be ok. I will disassemble the JBL this weekend and will keep you informed about the process of restoring. And the very best : I got them for free......
