Some newer speakers have a synthetic rubber surround/hinge but the foam ones are almost as common as the paper ones were. In the past there were a lot of problems with the foam disintegrating, especially the orange colored foam, you see a lot of replacement kits for sale for those types. I like the speakers that used a leather or chamois surround/hinge, they seem to be the most durable provided they were stored properly.
