Because of it's higher elasticity, rubber does a far superior job of 'edge termination'. Besides the small difference in cost, the down side of rubber is mainly that it is heavier than foam, thereby reducing the speaker's efficiency.Foam surrounds can also easily be made stiffer than rubber, and are therefore better suited for certain applications.
The new-age material for surrounds is a Thermo-Plastic Elastomer -
Santoprene. (www.santoprene.com). This offers advantages of both rubber (better damping, longer life), and foam (lower weight, controlled stiffness & lower cost).
