jbl 2425h foam replacement

[glenn]

I have a pair of 2425h compression drivers. I open them up to do an inspection and found the foam is goo and some of it is on the diaphram . I was able to clean the diaphram with alcohol and a gentle touch. Does anyone know what I can replace the internal foam of these drivers with?
regards,
Glenn

You can take it off and don't need to replace it.
