And stands are especially helpful in the low-frequency area, as this part of the frequency spectrum is omnidirectional and therefore more sensitive to surfaces nearby than the high-frequency area.
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.
The heavier the stand, the less it will move, and with many hi–fi and pro–audio speaker stands (including many of the models made by Atacama, for example), it’s possible to fill the hollow support column with a heavy material to add mass and to damp resonances. This could be sand, shot or any other heavy but well–damped material.
If the output from the sub seems uneven, you need to try and find a location where it produces a less lumpy response. A good tip for doing this is to temporarily place the sub where you normally sit to mix, and then listen at different places around the edges of the room while playing back a same level chromatic (semitone) scale of sine waves from a sampler until you find the spot that produce the most consistent level across all notes.
It’s physics: for every action, there’s an equal and opposite reaction.
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.
