Furthermore, in accordance with Newton’s third law of motion (each action has an equal and opposite reaction), whenever the speaker cone moves in one direction it will try to push the speaker cabinet the other way.
One way to improve the situation is to add mass by means of a platform fixed to the top surface of the foam. Primacoustic do this in their Recoil Stabilizer by using a very thick steel slab with rubber matting on top, while Auralex and other companies use MDF topped with dense rubber on their more up–market platforms. IsoAcoustics take yet a different approach, by using a frame made from rigid components joined by resilient isolators.
One of the roles of an effective speaker support is to prevent such vibrations from being transferred into other structures, such as wooden floors, desktops, shelves or mixer meterbridges. It should also hold the speaker as firmly as possible, to reduce movement due to the action/reaction effect.
