The SLX Series is a professional quality stand which caters for larger bookshelf speakers where an increase in the footprint is required to ensure optimum stability.
You could just plonk your speaker onto the top of your chosen stand, of course, but it’s best to have the speaker fixed to the stand in some way, because otherwise it can slide around. One popular and effective method is to place blobs of Blu–Tack under each corner; this acts as both a removable adhesive and as a damping medium. Another alternative is to use high–friction rubber matting, of the type sold for workshops and kitchens.
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.
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.
One way to improve the situation is to add mass by means of a platform fixed to the top surface of the foam. Primacoustic do this in their Recoil Stabilizer by using a very thick steel slab with rubber matting on top, while Auralex and other companies use MDF topped with dense rubber on their more up–market platforms. IsoAcoustics take yet a different approach, by using a frame made from rigid components joined by resilient isolators.
