Bang & Olufsen Penta speaker repair midrange foam surrounds.

The foam surrounds of Bang & Olufsen Beovox / Beolab Penta midranges get after a while decayed. We have a simple solution to repair these speakers with a small amount of tools. P.S. Always stick/push the surround on the cone or frame first time crosswise till it's firmly attached. You can use sticker-remover for the frame, but you will damage the cone with this liquid. The covers of the B&O Penta can be easy demounted on this video: https://www.youtube.com/watch?v=P3rd3NTQ-iM. Detend Penta dust cap repair: https://www.youtube.com/watch?v=0D6gi5WqiyI.
