9. Equalisation

VSXNET loudspeakers are designed to need no equalisation or correction to overcome system limitations. As a

result, they will only need equalisation to compensate for difficult acoustic environments.

Over equalisation can reduce system headroom, and introduce phase distortion resulting in greater problems

than cures. If equalisation is required then it should be applied gently and smoothly. VNET full range

loudspeakers are point source, phase coherent designs and violent equalisation will be detrimental to the

overall sound quality.

When a loudspeaker is used in close proximity to another, comb filtering effects can create coverage problems;

comb filtering creates an uneven frequency response across the coverage area due to constructive and

destructive interference effects between the sources. The amount of comb filtering is affected by the spacing of

the relative sound sources. Minimising this effect cannot be cured by equalisation (see the following section for

more details).
