Replacing speaker foams on old loudspeakers
There are a lot of old loudspeakers that are still in very good condition and should not be thrown away. However one problem is often the foam and rubber rings on the speaker chassis. While foam surrounds are very good from an acoustical point of view, there is one imminent problem: aging. Foam surrounds usually have to be replaced after 10 years. Sometimes, they work a bit longer, but it’s unlikely that you will find a 20-year old speaker with foams surrounds that is still ok.
The good news: These can be replaced relatively easily. Bang & Olufsen Create created a small guide that shows how to replace these. While the guide shows this on a CX50 speakers, the process is basically the same for other speakers.
