Subwoofers can be placed directly onto solid floors, but an isolation platform of some type will help clean up the sound if that floor is made of wood or chipboard. It isn’t a good idea to position subs very far from the floor — up to about 150mm shouldn’t present a problem, but more than that and the reflections can start to cause issues.
Fortunately, we don’t need to balance the speaker on actual springs, as a suitably dense piece of acoustic foam can act as both spring and damper. The speaker cabinet provides mass — so sitting a speaker cabinet directly onto a piece of foam, such as an Auralex MoPad, will bring about an improvement in the amount of vibrational energy getting through to the desk. However, foam isn’t particularly rigid, so the cabinet may still tend to move back and forth slightly as the speaker cones move, especially if the speaker cabinet isn’t particularly heavy.
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.
It’s physics: for every action, there’s an equal and opposite reaction.
