Help with Refoaming speakers

I have a set of Revel F52 speakers that I recently noticed cracks and tears in 2 of the right speakers bass drivers rubber rings.

Revel doesn’t refoam them and they no longer have replacement speakers for the base section.

So, do any of you know a reliable refoaming service? The drivers are fine.

I am in the Philadelphia, Pa area but will ship to any company that is great at refoaming. 

Peace
