Centre Channel speakers require dedicated stands as they tend to be of unconventional dimensions. The CC Series provides that solution and are available in a wide range of height options.
If you already have a pair of simple foam speaker platforms, you can improve their performance simply by gluing a heavy floor tile to the top. Ordinary contact adhesive works fine for this. Then you can either glue some kitchen mat to the upper surface, to provide some grip, or use Blu–Tack, as discussed earlier, between the tile and the loudspeaker.
Of course, you do still need to attend to room reflections by adding some basic acoustic treatment — but that’s another subject and one that we have covered on numerous occasions in our Studio SOS series.
The heavier the stand, the less it will move, and with many hi–fi and pro–audio speaker stands (including many of the models made by Atacama, for example), it’s possible to fill the hollow support column with a heavy material to add mass and to damp resonances. This could be sand, shot or any other heavy but well–damped material.
And according to Otto Jørgensen, this is where you have the most to gain from acquiring a pair of speaker stands: “The most impactful benefit of getting stands is added distance between your speakers and surfaces. It keeps early reflections to a minimum. And that’s especially important for the speakers’ low-end performance.”
You can make a speaker move less in many different ways, and one of those is by adding more mass to the speaker and the stand; making it harder for the speaker to move. That’s why you’ll find a sand compartment in most stands.
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.
