Many stands come with a compartment dedicated to sand and similarly heavy and well-damped materials. And there’s method in the madness. You see, the speaker plays music by moving its drive unit in and out to create sound pressure: when the drive unit pushes outwards, it creates sound pressure, but when it moves inwards it pushes the entire speaker backwards.
If you already have a speaker stand with spikes and your floor is made of wood, then you should consider putting some form of isolation platform between the speaker and the stand, to prevent the cabinet vibrations reaching the stand and, through it, the floor. Avoid flimsy stands that move or rock when you touch them. If the final assembly doesn’t feel completely solid, avoid it.
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.
