8. Arraying
As discussed in the previous section, comb filtering is a phenomenon, which cannot not 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 V12HP cabinet greatly
simplifies the creation of effective arrays, allowing seamless wide (130 degree) horizontal coverage
using two loudspeakers without the need for tedious experimentation.
By placing the V12HP cabinets with the 30 degree angled rear panels together, minimal dispersion
pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.
In many applications the 75-degree dispersion pattern may be sufficient in the horizontal plane.
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.

s shown in the above diagram, one of the V12HP cabinets is inverted to allow the optimum
splay angle to be achieved. The grill can be simply removed from this cabinet and be replaced
in the correct orientation. The grill is held in position by the two fixing screws on the top and
bottom lips of the cabinet.
