SPEAKER PLACEMENT GUIDELINES (CONTINUED)
Pole Mounting
Using the 1/4”, 20-threaded
inserts on the rear of the Klipsch
CP speakers and pole mount
brackets from a third party
provider, the speakers can be
mounted to light poles, etc. to
cover a 360° pattern for areas
such as parking lots indoor/
outdoor malls, etc.
Inverse Square Law
For every doubling of distance
from a speaker SPL is reduced by
6dB (-6dB)
EXAMPLE
Speaker Sensitivity:
91 dB@1 watt, 1 meter
X (1m) = 91 dB
Y (2m) = 88 dB
Z (4m) = 85 dB
Other Guidelines:
• Mount speakers at same height for clearest sound quality
• Sending a mono (left + right) signal to each speaker is typical
in a distributed audio system and gives the best coverage for
large areas
• Maintain an unobstructed “line of sight” between speakers and
listening area
• Rooms with hard surfaces (bare walls, hard floors and ceilings)
are considered “live” or reverberant and are best covered with
more speakers at lower output levels
• Rooms with soft surfaces (drapes, wall hangings, carpet,
upholstered furniture) are considered “dead”, absorbing sound,
and may require additional speakers placed closer together
Ambient Noise Levels: Measure at peak business hours to determine highest level
Background Music Levels: Usually 3-6 dB above the ambient noise level of a room
Foreground Music Levels: 10 dB+ above the ambient noise level of a room
