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.
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
