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.
It’s physics: for every action, there’s an equal and opposite reaction.
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.
You may have noticed that some speaker stands are fitted with spikes on the base, which help to make a rigid and stable contact with the floor. As long as the stands are both robust and stable, this strategy works well on solid floors, but you may find that it causes problems on wooden floors, due to vibrations from the speaker cabinet being transferred to the floor via the rigid stand and spikes. The floor will then act as the king of soundboards!
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.
There you have it; the basics of why you should consider stands for your bookshelf speakers. As with much in hi-fi, this is only the introduction to a massive subject, but it serves as a good understanding of stands function and what they can do for your hi-fi system. And they can do a lot for providing your speakers with the optimal condition for top-notch performance.
