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.
You can make a speaker move less in many different ways, and one of those is by adding more mass to the speaker and the stand; making it harder for the speaker to move. That’s why you’ll find a sand compartment in most stands.
Speaker positioning is critical when it comes to creating the ideal soundscape. KEF Performance Speaker Stands were engineered in the UK specifically to ensure bookshelf speakers sound at their best. This encompasses ideal driver height positioning, steel damping plates accompanied by aluminium tube and base plates, and space available for the addition of inert filler for further stability. The Performance Speaker Stand is ideal for the LS50 and LS50 Wireless, but can also be utilised by other KEF Bookshelf Speakers.
Thus, the sand provides dampening, but it also prevents the stand from ringing when it’s excited by the right frequencies – another handy little add-on.
