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.
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.
The theory is that the mass and spring characteristics are chosen so that the resonant frequency of the combination is well below that of any frequency they’re likely to be asked to isolate. For example, if the lowest note a speaker can reproduce is 30Hz, then the resonant frequency of the supporting platform needs to be well below that — perhaps just a few Hertz or less.
