Overlap Patterns
Overlap patterns offer better sound saturation and
are well suited for noisy applications. They also offer
more uniform coverage when background music or
sound masking (white noise/pink noise) is part of
the system.
Horns and Their Applications
Speaker horns are primarily used in noisy areas.
However, because they can cover enormously large
areas, they are also well suited for use in warehouses,
shipping departments, lots, garages, etc.
Horns perform best and cover the largest areas when
they are mounted 5' above the floor and set at a
60° angle of projection across the room.
Because horns have such large coverage areas, you
need fewer of them.
Quiet Areas <70 dB
 horn per 4,000 square feet
Moderate Areas 71-85dB
 horn per ,500 square feet
Noisy Areas >85dB
 horn per ,00 square feet
Never point speaker horns at each other. The sounds
cancel each other, cause reverberation, distortion, and
delay.
VIKING
The minimum overlap pattern eliminates dead zones and
reduces falloff. The full overlap pattern ensures consistent
sound volumes throughout the entire pattern.

For best coverage speaker horns should be mounted 5' off
the floor and tilted at a 60° angle.
60 Feet
40 Feet
The proper pattern for mounting speaker horns. All horns
point in the same direction with 60' downrange spacing
and 40' spacing side-to-side.
