8. Equalisation
VX Series loudspeakers require no equalisation or correction to overcome system limitations; equalisation
is necessary only to compensate for difcult acoustic environments. Over-equalisation can reduce system
headroom and introduce phase distortion, resulting in degraded sound. If equalisation is required, it should
be applied gently and smoothly. Because VX Series loudspeakers are point source, phase coherent designs,
excessive equalization usually proves detrimental to the overall sound quality.
When one loudspeaker is used in close proximity to another, comb ltering effects can create coverage problems.
(Comb ltering creates an uneven frequency response across the coverage area due to constructive and
destructive interference effects between the two sources.) Comb ltering cannot be cured by equalisation;
this should be addressed with proper arraying as discussed in the following section.
