I literally wanted to post the same question today.

I just replaced the woofer-surrounds on mine and noticed that the most of the foam has disintegrated.

Correct me if I'm wrong, but it didn't seem like the foam is in direct contact with the PCBs like in the 4000s, so it probably isn't quite as dangerous. 

Nevertheless, speakers with actual foam inside, instead of rotting glue, probably sound better.

That is exactly my opinion. I love the design of my BeoLab 6000's and I want to keep them for as long as it is possible. I just ordered new speaker cloth and will try to wrap the speakers with high gloss car foil.

I will start the project next week and will post the progress here.

Why would you wrap the speakers in foil?

Is the aluminum damaged? Color change?

Very much looking forward to pictures 🙂

No the aluminium is absolutely perfect but I want a pair of black ones for my office. I will send extra detailed pictures of the wrapping.

WD 40 is not a contact cleaner. Keep that well away from anything audio.

WD-40 is the company name  ;-) And yeah their most popular product has the same name but actually they have contact cleaners etc for industry. We use them in the office for our cloud computing server farm and the product is great.

This is the cleaner I use since years and it is amazing. You can use it with your Server while it is operating etc. 

Okay then! Thanks.

Did you make any progress, Tim?

Does anyone know where to get the foam dampeners inside the BL6000?

I tried to talk to my local dealer but they were very, very anti-DIY and not cooperative. (I asked them about new foam pieces, they told me that I should let them replace all 6 driver chassis in their service center... thanks...)

Alternatively does anyone have experience with making dampeners themselves (what material to use etc.).

From the service manual i know the rough shape, but not the dimensions.

I did make a bit of progress but currently I am packed with work so this little project has been on hold a bit. In generall I have made the same experiences like you with B&O dealers. 

What I did so far:

- Speaker foam repair on all 4 speakers

- Search and find the perfect new fabric for the BeoLabs [
