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.
One way to improve the situation is to add mass by means of a platform fixed to the top surface of the foam. Primacoustic do this in their Recoil Stabilizer by using a very thick steel slab with rubber matting on top, while Auralex and other companies use MDF topped with dense rubber on their more up–market platforms. IsoAcoustics take yet a different approach, by using a frame made from rigid components joined by resilient isolators.
The HMS Series is considered to be Audiophile level by many and incorporates a significant increase in mass loading capacity and designed with very high quality speakers in mind such ProAc and other premium manufactures.
And, of course, it needs to put the speaker in the correct position relative to the listener, which usually means with the tweeter aimed at an imaginary point just behind the listener’s head. Note, though, that a few speakers are deliberately designed to be aimed directly ahead rather than at the listener, so always check the recommendations in the manual that comes with your particular loudspeaker before directing them inwards.
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.
It’s physics: for every action, there’s an equal and opposite reaction.
