In this episode you are able to watch how to disassembly, clean and install new isolation materiale inside your Beolab 8000 Active Loudspeakers.
The video are in 3 episodes where we start by removing all parts from the Bang & Olufsen Beolab 8000. The process starts with the removal of speaker units as well as the electronic components and then we clean the cabinet from the old insulation material. The successors continue to clean the electronic components. Finally, new insulation material is installed inside the Beolab 8000 cabinet.

Congratulations! This is indeed an excellent tutorial! I whish I had seen this tutorial before I had cleaned my 6 units of Beolab 8000 loudspeakers. I hope that the new foam material does not degrade as the origiginal material did. I had only installed one set, since this was the only one I could order. Instead of a brush and liquid alcohol, I had used Isopropyl cleaning spray "IPA", "WL" and "61" (all from German supplier "Kontakt Chemie") and thereafter compressed air to clean the amplifyer and Power-supply board. This made the cleaning process of the electronics much easier. However you have to make sure not to blow the degraded foam all over the place!
With one of the 6 loudspeakers, I´m facing a problem, that is most probably related to the black relais on the Power -Supply board. When the Beolab 8000 is connected to my Ouverture 2631 and i.e. a CD is played, the LED at the Beolab 8000 changes from RED to Green (as usual), however there is no sound fgrom the Beolab 8000. If then the 230 V power supply-cable at the Beolab 8000 is disconnected and then connected again, the function of the loudspeaker is normal. I guess that relais has a bad tontact and needs to be replaced. What do you think?
I appreciate your feedback and am happy that you find the film enjoyable. Since the new foam substance is a different kind of material, it won't deteriorate.
I appreciate your suggestion to try a different cleaning technique; I'll utilize this one the next time. "cleaning spray "IPA", "WL" and "61" (all from German supplier "Kontakt Chemie")"
Sound like you have a bad amplifier board. Send us an email and we can take the conversation there.
I have these exact Beolab towers with the same issues. One Board's tracers are corroded from rotten insulation foam...so i put them in storage 3 years ago to wait until there were more tutorials, and today i find this outstanding tutorial, so time to get them out of storage for repair!! thanks alot!

amazing tutorial. Thanks for giving info on a specific product like this!!
You're welcome.
Thanks for the tutorial!
I would like to point out that you should also remove the old foam tape that seals the case to the front. I got a roll from my local B&O.
Thank you for your comment. That's a very good point and good idea to do. Do you know where to get the new foam tape for sealing?

Great video. Please tilt the camera so we can use all of the screen. And better sound.
Hi Henrik-Pedersen.
Thank you for your comment. I could't not use full screen doing to long speaker and studio setup. Maybe when I get a bigger apartment and will do a video studie and get better shots.
These videos are awesome! Do you show how to take the top cap off?
Hi bryanwest9196
I'm glad for you like the video. Inside the cabinet, at the centre of the top middle corner, the top cap is secured by one screw.
I hope this will help you.

I have a problem with my amplifier board. I could not see it in your store. Is it still available?
Yes, I have the amplifier on stock. Send me e-mail to contact@kosetrading.com and we can take the details.
Awesome video! I have a pair of 8002’s and was wondering if they would have similar foam issues. I have heard that some of the newer Beolab 8000’s have the new white foam so wasn’t sure if I should look at replacing the foam in the 8002’s as a preventative measure.
Hi. Thank you for your comment. The Beolab 8002 is the latest version of the beolab 8000 line and they have definitely improved the cabinet and the amplifier with new white foam.
Thank you so much for your reply and letting me know that information! Amazing!
@@xyphonfilter You are welcome. All those who own Beolab 8000 have the right to know about this problem so that they can avoid problems in the future.
