Looks like you need some new dust caps for those woofers, though the foam surrounds look fine. I'd replace them with the original paper type and not poly. Find a replacement that is as close to the existing dust cap size as possible. You can install them using white school glue from any store that sells school supplies - typical "black" speaker glue is just the same sort of PVA-based glue with a rubberizing additive and black pigment.
