A speaker platform is designed primarily to provide a degree of mechanical isolation between the speaker and the surface upon which it is placed, while keeping the speaker firmly in place. This is particularly important when siting speakers on lightweight desks or shelves, as these can easily be set into vibration if in direct contact with a speaker cabinet.
We might call them bookshelf speakers, but does that mean it’s a good idea to put them on one? Nothing is stopping you from doing it, but it’s your sound performance that’s at stake – and there’s much to lose – and, if you’ve just shelled out a significant amount for your new speakers, it’s a bad start to what should be a great investment.
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.
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.
Where vibrations are allowed to leak into any studio furniture or wooden floors, the audible result is often a blurring of the bass and lower mid range, as well as a deterioration in the stereo image. By using an appropriate stand or platform, the bass end should tighten up to a very noticeable degree, leaving the mids sounding clearer and the imaging better defined.
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.
