You could get to buy the right size and suspension material, a good one from a spare shop dealing in speaker diapharam, coils, spiders and surrounds. If you can paste the suspension without removing the coils it would be good. but if the spider had come off, remove the coil/paper carefully, fix the suspension, use a thin film inside of the coil insert to centrallise the coil between the magnets and paste the spider/ suspension after removing the film. The speaker must move without any rubbing to finalise your fixing. allow it to dry, connect the coils and test. You must take patience and time to get this right and you can. Do not park your car in open sunlight/ accumulating dust, to reduce further weathering. Good day
