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.
Of course, you do still need to attend to room reflections by adding some basic acoustic treatment — but that’s another subject and one that we have covered on numerous occasions in our Studio SOS series.
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.
The SLX Series is a professional quality stand which caters for larger bookshelf speakers where an increase in the footprint is required to ensure optimum stability.
Even if you already have a loudspeaker stand, you can still use one of these foam–based speaker platforms on top of it to reduce the amount of vibration getting into the stand and subsequently into the floor. Many of the commercially available platforms come with additional foam wedges that may be used to adjust the vertical angle of the speaker if necessary.
And stands do more than combatting early reflections. They also provide what’s called decoupling between your speakers and the floor (which is also known as mechanical isolation). We will let Otto describe their construction: “Take your typical Dynaudio Stand; you have feet with either spikes for solid floors or rubber for wooden ones at the bottom. Then you have a base plate that manages vibrations. Also, large base plates with feet far apart are more stable, making it harder for the speakers to fall over.
