That’s where you need to put the sub. If your sub has a phase adjustment knob, or a polarity–invert switch, adjust this until you hear the loudest result from frequencies around the crossover point, typically 80 to 120 Hz.
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.
And stands do more than combatting early reflections. They also provide what’s called decoupling between your speakers and the floor (which is also known as mechanical isolation). We will let Otto describe their construction: “Take your typical Dynaudio Stand; you have feet with either spikes for solid floors or rubber for wooden ones at the bottom. Then you have a base plate that manages vibrations. Also, large base plates with feet far apart are more stable, making it harder for the speakers to fall over.
