Replacing foam on Beovox CX 50

So I bought a set of second hand Beovox CX 50 and was hoping to get started using them but turns out the foam is damaged so this needs to be fixed. I spoke to the local B&O service company and they told me that they do not do it as its a difficult job and can go wrong easy which will then affect the sound quality. Is this accurate?

He advised buying new speakers and just replacing them, any thoughts?

If the speaker cones are moving freely it is easy to "refoam", search the forum for foam surrounds, refoaming, speaker surrounds or surround repair, follow instructions and it is an easy task.

And welcome to the forum

 

The CX speakers may not be the most difficult but it can certainly go wrong, if you're not the DIY type.
Many failed attempts have ended up on my doorstep with a note crying for help, - I've lost count.

Where are you located?

 

I've seen a few sets sell in Australia lately sell and all have had foam rot, the sellers seem to think it's not a problem when I question them about it. I generally ask as I'm always looking for sets of these, but not prepared to outlay too much if they need work..

Like many on this forum, I have reformed plenty of speakers. You can find tutorials on YouTube too. If you are patient, methodical and follow instructions properly, you can gain a lot of pleasure by doing this yourself. It's not a job that takes 20 minutes. You need to invest the time to do it hence the expense when someone does it on your behalf. The materials only come to about 16 EUR or so to reform a pair of these, new drivers will cost much more and if original will have the same problem.

To be more sure of success, use the 'shimming' method to centre the voicecoil whilst you work. Just be careful and accurate when you cut the dust cap and hinge it back (don't remove it completely).

As suggested, search the forum as there are certainly threads on reforming CX100, 50, S45's and more. It can seem daunting if you've never done something like this before, it did to me but I loved it when I'd finished and brought them back to life for the next 20+ years,

Good luck and welcome to the forum.

Dave.
