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.
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.
The HMS Series is considered to be Audiophile level by many and incorporates a significant increase in mass loading capacity and designed with very high quality speakers in mind such ProAc and other premium manufactures.
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.
Many stands come with a compartment dedicated to sand and similarly heavy and well-damped materials. And there’s method in the madness. You see, the speaker plays music by moving its drive unit in and out to create sound pressure: when the drive unit pushes outwards, it creates sound pressure, but when it moves inwards it pushes the entire speaker backwards.
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.
