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.
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.
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!
So, what should you do instead? We’ve talked to our product team to learn more – and the solution is stands. Sideboards, tables and chairs are out of the question, too. Speaker stands are specifically designed to bring the best out of your speakers by managing vibrations, reducing early reflections and ensuring the proper amount of treble. Together with our Product Manager - Home, Otto Jørgensen, we’ve taken a look at the fundamentals.
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.
A cheap DIY option is to build a couple of towers by stacking concrete blocks or bricks. This low–cost approach really works — we’ve used it successfully on more than one Studio SOS visit — and because of the high mass, very little vibrational energy makes it through to the floor. Some people like the rugged appearance of bricks, but if it’s not to your taste you can always disguise them with cloth drapes, or even spray them gold if you like that kind of thing!
