To sum up, the platforms with a heavy plate of some type on top are the most effective, though you can add mass very easily to any type of support by using floor tiles. Similarly, the more massive and better damped a speaker stand, the less vibrational energy is likely to make it through to the floor and less the stand itself will vibrate. Compared with the cost of speakers, adding suitable stands or platforms is relatively inexpensive, yet it can make a very worthwhile improvement to the overall sound quality!
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.
Thus, the sand provides dampening, but it also prevents the stand from ringing when it’s excited by the right frequencies – another handy little add-on.
