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.
Where vibrations are allowed to leak into any studio furniture or wooden floors, the audible result is often a blurring of the bass and lower mid range, as well as a deterioration in the stereo image. By using an appropriate stand or platform, the bass end should tighten up to a very noticeable degree, leaving the mids sounding clearer and the imaging better defined.
A speaker platform is designed primarily to provide a degree of mechanical isolation between the speaker and the surface upon which it is placed, while keeping the speaker firmly in place. This is particularly important when siting speakers on lightweight desks or shelves, as these can easily be set into vibration if in direct contact with a speaker cabinet.
That’s where you need to put the sub. If your sub has a phase adjustment knob, or a polarity–invert switch, adjust this until you hear the loudest result from frequencies around the crossover point, typically 80 to 120 Hz.
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.
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.
