Many stands come with a compartment dedicated to sand and similarly heavy and well-damped materials. And there’s method in the madness. You see, the speaker plays music by moving its drive unit in and out to create sound pressure: when the drive unit pushes outwards, it creates sound pressure, but when it moves inwards it pushes the entire speaker backwards.
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.
There you have it; the basics of why you should consider stands for your bookshelf speakers. As with much in hi-fi, this is only the introduction to a massive subject, but it serves as a good understanding of stands function and what they can do for your hi-fi system. And they can do a lot for providing your speakers with the optimal condition for top-notch performance.
You could just plonk your speaker onto the top of your chosen stand, of course, but it’s best to have the speaker fixed to the stand in some way, because otherwise it can slide around. One popular and effective method is to place blobs of Blu–Tack under each corner; this acts as both a removable adhesive and as a damping medium. Another alternative is to use high–friction rubber matting, of the type sold for workshops and kitchens.
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.
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.
