6. Equalisation
The VXP loudspeaker requires no equalisation or correction to overcome system limitations; equalisation
is necessary only to compensate for difcult 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 VXP loudspeakers are point source and 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 equalization;
this should be addressed with proper arraying as discussed in the following section.
