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.
An isolation platform works in a similar way to a car’s suspension, and comprises three mechanical components: a spring, a mass supported by the spring, and some form of damping to prevent the sprung mass from continuing to bounce around. In a car you have the springs between the axles and the car body: the car body provides the mass and the shock absorbers provide the damping, to stop you having a bouncy ride.
We tend to think of a loudspeaker as a fixed box that produces sound directly from the moving cones of the speakers (and, where the speaker is ported, from the port as well). Although that is certainly where most of the sound comes from, the reality is that no matter how rigid the cabinet is there will also be some vibration of the cabinet walls.
A cheap DIY option is to build a couple of towers by stacking concrete blocks or bricks. This low–cost approach really works — we’ve used it successfully on more than one Studio SOS visit — and because of the high mass, very little vibrational energy makes it through to the floor. Some people like the rugged appearance of bricks, but if it’s not to your taste you can always disguise them with cloth drapes, or even spray them gold if you like that kind of thing!
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.
Centre Channel speakers require dedicated stands as they tend to be of unconventional dimensions. The CC Series provides that solution and are available in a wide range of height options.
