I have a pair of these vintage Jamo CBR Mini speakers which need some repair. Has anyone ever successfully opened one of these up without damaging it too much?
There are no screws anywhere, I'm afraid it is completely glued. I hope to find someone here who found a method of opening them up!

Had a subwoofer with the same problem and the same rubber inserts. Pull the inserts out I believe the screws will be there.
If there are no screws behind the rubber inserts, you could pull off the foam around the tweeter.
Jamo has a reputation of not being very service friendly and had a lot speakers which were glued shut and the crossover was only accessible through the opening of the woofer. They often even glued in the crossover and the speaker terminals.
It might be possible there are screws behind the plugs of the cover, the chances are slim though because with just 4 screws the baffle would not be held down tight over the years and start to rattle, even with a sealing foam gasket. And there would be a visible gap. And there would not be much material left to hold on for the screws because the baffle isn't very thick. I would try that anyway since it's seemingly the last non-destructive way to access the inside.
If the speaker is actually glued shut, the best method to open it is to use a jigsaw and cut the back wall out with leaving a ring of ~2-2,5cm away from the side walls still standing. That way you have enough material left as a kind of flange so you can screw a new backside onto it to close it again.
You should try to locate the crossover first to locate the crossover. It's possible it's glued to the back and you don't want to jig-saw through it. Other possible positions (aside from the walls) are on the other side of the terminal or glued to the drivers.

Thanks for the replies guys. There are no screws behind the plugs, the baffle really is glued. I was hoping someone managed to open one up from the baffle somehow. The jigsaw is a good idea..i might give that a go.
