Even if you already have a loudspeaker stand, you can still use one of these foam–based speaker platforms on top of it to reduce the amount of vibration getting into the stand and subsequently into the floor. Many of the commercially available platforms come with additional foam wedges that may be used to adjust the vertical angle of the speaker if necessary.
A cheap DIY option is to build a couple of towers by stacking concrete blocks or bricks. This low–cost approach really works — we’ve used it successfully on more than one Studio SOS visit — and because of the high mass, very little vibrational energy makes it through to the floor. Some people like the rugged appearance of bricks, but if it’s not to your taste you can always disguise them with cloth drapes, or even spray them gold if you like that kind of thing!
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.
