should also avoid putting them into enclosed spaces, such as under desks with side panels, as this creates a resonant system that can further mess with bass clarity and evenness. Also be aware that you need to maintain a minimum distance between the cabinet and walls when positioning both rear–ported subwoofers and speakers. Details of how far this needs to be should be included in your speaker or sub’s manual.
And, of course, it needs to put the speaker in the correct position relative to the listener, which usually means with the tweeter aimed at an imaginary point just behind the listener’s head. Note, though, that a few speakers are deliberately designed to be aimed directly ahead rather than at the listener, so always check the recommendations in the manual that comes with your particular loudspeaker before directing them inwards.
Even if you already have a loudspeaker stand, you can still use one of these foam–based speaker platforms on top of it to reduce the amount of vibration getting into the stand and subsequently into the floor. Many of the commercially available platforms come with additional foam wedges that may be used to adjust the vertical angle of the speaker if necessary.
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.
The theory is that the mass and spring characteristics are chosen so that the resonant frequency of the combination is well below that of any frequency they’re likely to be asked to isolate. For example, if the lowest note a speaker can reproduce is 30Hz, then the resonant frequency of the supporting platform needs to be well below that — perhaps just a few Hertz or less.
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.
An isolation platform works in a similar way to a car’s suspension, and comprises three mechanical components: a spring, a mass supported by the spring, and some form of damping to prevent the sprung mass from continuing to bounce around. In a car you have the springs between the axles and the car body: the car body provides the mass and the shock absorbers provide the damping, to stop you having a bouncy ride.
