Large Space / Open Office Speaker Spacing
Speakers are typically placed in or above a ceiling in a consistent square / rectangular grid pattern with the ultimate goal of
providing uniform sound coverage throughout a space. In cases where an open ceiling or partial ceiling exists, optional
brackets allow for constant height attachment to wood, structural steel, and flush mounting in solid surfaces such as drywall
and wood panels. Speaker spacing is based on ceiling / mounting height.
Lencore speakers have the same minimum and maximum spacing requirements from acoustic boundaries such as walls or
columns. If a device is too close or too far away from a boundary, a change in sound level
may be discernible by occupants
and should be avoided .
In the case where an in-ceiling conflict occurs (i.e., a light fixture, exit sign, sprinkler head), it is permissible to move a speaker
up to 2’ in any direction to avoid the conflict. However, ensure that the most consistent spacing possible is achieved to keep
variations to a minimum.
