Well considering the sub was put together with ca glue id use it and find a way to clamp it for a few hours ...what caused the issue is the question u need to ask...too much power ? clipping? over excursion ? improper box ? what sub?
put up a pix. reason being you could see some glue cracking or seperation cone to spider and not be a problem. as long as the parts arent loose and the spider is still glued to the former and so is the cone your fine.
lots of time there is extra glue there and the spider if pushed hard enuff can seperate from the glue a bit,pix will tell all...
