7.0: ARRAYING
As discussed in the previous section, comb filtering 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 PowerV™ cabinet greatly simplifies the creation
of effective arrays, allowing seamless wide horizontal coverage using two loudspeakers without the need for tedious
experimentation.
By placing the PowerV™ cabinets with the 30 degree angled rear panels together, minimal dispersion pattern overlap is
achieved, guaranteeing an extraordinarily smooth transition. In many applications the 90-degree (75 - degree on the
PowerV12HP™ and PowerV15™) 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.
As shown in the above diagram, one of the PowerV™ 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.
