We might call them bookshelf speakers, but does that mean it’s a good idea to put them on one? Nothing is stopping you from doing it, but it’s your sound performance that’s at stake – and there’s much to lose – and, if you’ve just shelled out a significant amount for your new speakers, it’s a bad start to what should be a great investment.
It’s physics: for every action, there’s an equal and opposite reaction.
You may have noticed that some speaker stands are fitted with spikes on the base, which help to make a rigid and stable contact with the floor. As long as the stands are both robust and stable, this strategy works well on solid floors, but you may find that it causes problems on wooden floors, due to vibrations from the speaker cabinet being transferred to the floor via the rigid stand and spikes. The floor will then act as the king of soundboards!
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.
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.
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.
