Their smaller stands are made from a type of plastic and their larger ones from cast metal. All are perfectly valid approaches. Note that some speakers, such as certain Genelec models and Event’s Opals, already come with resilient isolating platforms or feet and so may not need additional treatment.
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.
Subwoofers can be placed directly onto solid floors, but an isolation platform of some type will help clean up the sound if that floor is made of wood or chipboard. It isn’t a good idea to position subs very far from the floor — up to about 150mm shouldn’t present a problem, but more than that and the reflections can start to cause issues.
