$36-$48 - Kelly. They aren't very tasty, but they sure are chewy. Stbhorn: Yes they work - if you want a fuller bass/mid bass sound. Don't know if this would be a good thing if the speakers are close to the wall though? For a few $$ you could also try one of the Blue Tack "like" products (sold @ stationary and hardware stores). The light blue product, made by DAP, is a good one that does not stain.
