Surround Treatment Goo

[Jim Easley]

Just exactly what is this stuff? I have several 515B's and a 604-8K that I am replacing the fabric surrounds on. The only information I have been able to find describes it as a "Polyvinyl Chloride Co-Polymer". Does anyone have a source for this goo?

Hi Jim,

Altec's Replacement diaphragm notes for drivers including the 515 refer to it's name as surround dope "Air-Flex 510". I don't know who supplies/supplied this, or whether it's still available.
