No, it’s not because we don’t like your bookshelf. It’s probably really good looking. But, bookshelves, sideboards, TV-boards and tables all share a common drawback: surfaces. You don’t want surfaces close to your speakers, as surfaces can cause early reflections that colour and distort the sound image – that’s also why we recommend getting your speakers away from corners and walls.
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.
All that unwanted movement can colour and distort the sound. We do our best to prevent vibrations by adding bracing to the cabinet, but that doesn’t really help with the movement.
Subwoofers can be placed directly onto solid floors, but an isolation platform of some type will help clean up the sound if that floor is made of wood or chipboard. It isn’t a good idea to position subs very far from the floor — up to about 150mm shouldn’t present a problem, but more than that and the reflections can start to cause issues.
