SOURCE: The 6.5 foam ring

This is a very common problem and I don't know why companies still use foam.

The ring is called the "surround" and the problem is known as "surround rot".

There are 3 fixes.

Replace the entire driver. (most expensive)

Recone the driver (tear out the old cone + surround + spider and glue in a new one using the old basket).

Refoam the surround. (replace just the foam surround).

I know of one location in my hometown (Ottawa Ontario, that does re-foaming and people that do this are few and far between).

If you can find someone to refoam it go that route, failing that do a recone. A recone will last just as long as a new driver.

Hope this helps!

Cheers,
