How did you mount your surrounds?

I have seen surrounds hanging directly on walls and some on shelfs. If wall mounted, how did you prevent vibrations from sub. I need to mount 4 Klipsch s1 surrounds. They only have one keyhole slot and I thought about putting the little silicone bumpers on the 4 corners. I might do this now and later on build small shelves the curved shape of the speaker to sit on if that is better. Which way is best?
