6. Equalisation
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. Violent equalisation will be detrimental to the overall sound quality.
7. Arraying
Comb filtering is a phenomenon, which cannot be cured by equalisation. Small alterations to loudspeaker positions can have the effect of minimising problematic combing frequencies. Arrays should be constructed so that the individual coverage patters of each loudspeaker combine with minimal overlap. The design of the iQ 10C cabinet greatly simplifies the creation of effective arrays, allowing seamless wide (120 degree) horizontal coverage using two loudspeakers without the need for tedious experimentation.
By placing the iQ 10C cabinets as shown in the diagram below, minimal dispersion pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.
It is also possible to stack the cabinets vertically using the above method, say for use in a central cluster, where greater vertical dispersion is required.
