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.
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.
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.
