COVERAGE
The distance you can be away from a speaker
and still have good talkback depends on the
ambient noise level. The pendant speaker will
cover approximately 250 square feet when
mounted 8' from the floor (talkback from 10'). Speaker coverage is dependent on
mounting height; the greater the mounting height, the larger the area covered.
