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.
It’s physics: for every action, there’s an equal and opposite reaction.
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.
If you visit the various hi–fi forums you’ll find a number of conflicting views on what the best material to use is, but there’s often little to back up people’s claims, and I’d suggest that that way lies madness! Dry playground sand works just fine, and you can even leave it inside plastic bags if you wish to avoid things getting messy.
The range begins with the award winning Nexus Series, a three column design made for the HiFi enthusiast. As with all Atacama speaker stands, Nexus allows you to increase the mass of the stand by filling the largest column with Atabites.
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.
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.
