Thanks for the photo.
Obvious a foamy rubbery surround.
I only know about the AD 8061 and 8066 types, 30 of them, all as new, can you tell me what material it's made off ? Everlasting, no crackles, no sweating, no hardening. Did Philips keep it a secret ?
The AD 7063 with impregnated cloth surround hardens, later types , f.e. digital series have quickly deteriorating surrounds, sticky after a few years. Old sixties harmonica surrounds, treated with silicon or not are also lasting forever, A 4201 M for example.
Anyway a good material is a choice the manufacturers make, but I think they don't WANT to make everlasting loudspeakers but sell updates every now and than. So, expensive, cheap or whatever is a gamble, minimising this gamble is chosing for silicon rubber what I think the 8061/66 is made of.
The nice looking surrounds of the Dali 606 bass/mid units are still very flexible when pushed with the finger, after 12 years, so also good ? Looks like solid (silicon ?) rubber.
Once in a while I build enclosures with the Philips units and gave them to friends and neighbours and they still are in use sounding as when I finished them. The 8066 are easy obtainable on Marktplaat/E-bay, also from the bin, alway's as new, it is my favorite loudspeaker as you can understand.
