Punctured Woofer


My little 4 year old used my martin-logan aerius woofer as a pincushion and put three 3mm sized holes in the cone. If I can get to them (don't know how yet) are they repairable by me. Is there a role for duct tape in this? Or do they go back to the factory for replacement? They have developed a mild rattling buzz where the holes are.
Thanks for any ideas

Use an epoxy they're very light and ridged. Just be sure to apply it very conservatively
Thanks to everyone for the suggestions. I get a sense that I can at least try to repair it by myself. Now if only I can figure out how to get the panels off.
