I give up. I want to refoam the bass speakers. I took the screws out of the face and can't open the box up. I removed the cross over in the back to see inside, the speakers are held behind the face. The box looks glued together. Anybody remove these speakers from the box before? Thanks.

Easy there just like most of the JBL control series, you first need to work-out like Arnold Schwarzenegger, :D as it requires muscles tough fingers!

Look at the diagram itís easy, itís only a sealant that goes around on the inside that makes it air-tight.

Youíd then need a smaller I hope you have smaller allanKey to remove the bass/mid driver.

Iíve had control 1 and 5 apart in less than 2minutes

There is re foam kit on fleaBay

I wonder what the timber balance would be like for matching against the Control on the HF end as the HF tweeter looks similar to one used in the Control 5. I think this model is also discontinued.

Man! You aint kiddin". I think I pulled a muscle. I have 3 pairs of discontinued JBLs. Just can't see myself getting rid of them. This is my "newest" pair. I am surprised the foam eroded on these first. Thanks for the info.

Thatís just typical isnít it? I think JBL needs their ass kicking and foam :dead_horse: should be BANNED! Rubber is durable ;) wouldn't you agree?

There are rubber edge surrounds for control 5 as and when the time comes, not sure about any rubber surrounds for the smaller JBL series family?

I read somewhere that if you live near to the ocean the foam surrounds deteriorate faster. Isnít JBL located on west cost near to the ocean?:hmm::D
