10 SPK-C613 - Installing the Open-back Ceiling Speakers
Figure 6: The Speaker Coverage Area
The coverage angle of the speaker determines the coverage area and the number
of speakers required in the array installation. Two patterns are usually used for
array installations, square (see
Figure 7 ) or hexagonal (see Figure 8 ), depending
on the shape of the installation area. The speakers are positioned according to
their coverage area.

You can set the power on each speaker to get the desired power level in different
installation areas.
