And according to Otto Jørgensen, this is where you have the most to gain from acquiring a pair of speaker stands: “The most impactful benefit of getting stands is added distance between your speakers and surfaces. It keeps early reflections to a minimum. And that’s especially important for the speakers’ low-end performance.”
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.
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.
