The Platinum 100 3G bookshelf speakers come with 8 self adhesive rubber feet in the packaging. These should be placed around the inserts on the bottom of the cabinet when placing the speakers on a shelf or when using third party stands for the speakers. This isolates the speaker to prevent it from moving.
