Now the last uncertainty I have some white school glue but it is water-based.
Apart from the applications (paper and other light materials) there is no more info on the container regarding it's composition.

Hi Your reparation looks as it should. But a word of caution, if the patches glued are not on symmetrical pattern around the outer edge, there is a possibility of voice coil rubbing against pole pieces when cone excursion is high, as the patched part maybe now flexing in different manner compared to original outer suspension. Same applies to repairing light or thin cones. If there is hole poked on one side,
just apply same kind of patch on the opposite side to keep mass
symmetrical around the voice coil and suspension. In this case as it is a low mid driver, maybe not so much.

seeing you are from the netherlands.. if u used "Knutsellijm" as used op school.. you are fine. reapply a few times though. i repaired some 15" jbls with it and they acted fine. not really waterresistant tough so make sure the speakerfoam is installed or such.

I did use "knutsellijm"
It had to be repaired at two areas, both being on one half I did apply the same on the other side. So now it is patched at four points (symmetrically and all backside). I don't expect to need much Xmax but it minor work to do it somewhat properly. I'll keep you informed the coming weeks
