Repair speaker cone

[CooperBox]

I see on a recent thread there is mention of speaker damage on a G4 Quicksilver, namely separation of a rubber membrane and tears of the speaker cone.
Which reminded me, I have a pair of G4 Cube speakers - model M7963 that are not aging well, and ideally need repair of the black cone material. (See photos below).
Has anybody here attempted such a repair? If so, could you please share what was the precedure, the material used, and was the final result satisfactory?

Wow that's some bad rot. I'd say get a surround repair kit but I'm unsure of where to get something that small.

Hmm, so on lesser damaged surrounds, (where the foam is not missing, just torn - & on 10" speakers) I've used brushed on dry-flexible rubber cement to sure them up with excellent (audibly silent) results.Those surrounds look pretty rough but at least as a stop-gap measure to stop further rot, I'd gently brush on a few layers of flexible rubber cement to the surround. Once shored up, to fill/address the gaps/missing bits, you could use some thin layers of something super thin like tissue paper. Cut them to fit, glue them on with the Cement, let it dry & then brush a few layers of the cement over that.

The above process is what I typically do to cone damage specifically. I've not tried it on the rubber/foam surround but if you're up for a project, you might give it a shot.

Good luck.

I think the best option is to replace the cone with those from a set of Apple Pro Speakers which used the white rubber. Its been pretty well documented as a great option which I intend to do on at least one set of my Cube speakers suffering rot like that.

Thanks for your replies. Good to know that someone appreciates my rot.......
I think I'll try RhianB`s suggestion first, and see how that turns out.
After posting yesterday, I did a more detailed web search and see there`s a clip somewhat similar to the one Hrududu referred to. That may be another solution, but would mean the purchase of additional speakers which I'd like to avoid if possible.
As it may interest others, below are interesting related video clips.

Think on AliXpress you can get the replacement rubber.

It's foam in this case.

I know, but the iMac G4 Speakers comes with white rubber, and they are exactly the same speakers.

So I guess in this case they can be easily repaired with this black rubber replacement. And maybe to last longer.

Only thing I'm not sure yet is the exact dimensions, I'll try next weeks.

This is an old thread, but just in case anyone is looking for a solution, I successfully restored the speakers over here: https://forums.macrumors.com/threads/cube-speakers.2180053/

sunapple Thanks for sharing. Do you think the rubber instead of foam can be a good replacement?
