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.
Furthermore, in accordance with Newton’s third law of motion (each action has an equal and opposite reaction), whenever the speaker cone moves in one direction it will try to push the speaker cabinet the other way.
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.
All that unwanted movement can colour and distort the sound. We do our best to prevent vibrations by adding bracing to the cabinet, but that doesn’t really help with the movement.
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.
Atacama offer a wide range of speaker stands with a choice of colours, dimensions and style to satisfy most requirements .
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.
