EX26 · Using Multiple Boxes
KV2 speakers are far more accurate, defined and phase coherent than virtually any other loudspeaker on the market.
This very defined phase accuracy comes into play when trying to stack the speakers.
It is very important not to use KV2 Audio Mid-High boxes directly side by side. (Fig. A) This will produce a poor quality
sound cancelling out perfectly, which reduces overall output. Defined by the way our ears work, their position on our
heads and the brain's understanding of the signals they produce, each ear will hear two sources in the horizontal plane
very close together, but very slightly misaligned in arrival time.
With our ears positioned on each side of our head, rather than on the top and bottom, they are very good at
pinpointing precisely a sound in the Horizontal plane (i.e. it's exact position left to right in the sound field). Vertically
(trying to pin point sound up and down) they are far less accurate and have a greater tolerance for error. Recieving
multiple signals so phase coherent, but misaligned horizontally, leads the brain to get confused, which in turn leads it
to interpret a confused poor quality, low intelligibility sound.
KV2 exploits the additional vertical tolerance that the brain has by only stacking multiple cabinets vertically, as do
modern Line arrays, but KV2 still keeps as close as possible to the theory of point source by using a maximum of two
cabinets together, keeping the horns as far apart as possible. (Fig. B) This reduces the cancellations that most line
arrays suffer from particularly in the high frequencies. The only exception to this maximum of two cabinets would be
in a down fill / side fill application where an additional cabinet can be deployed but must be separated from the main
forward firing system by an amount of degrees equivalent to the vertical or horizontal dispersion of that speaker. (Fig. C )
Combining boxes and building systems in this way will give the maximum overall output, best audio quality
and consistent, even coverage.
