CHAPTER 4: CAL COVERAGE

VERTICAL BEAM SPREAD

All CAL loudspeakers include vertical beams with variable

spreads from 5 to 30 degrees in 5-degree increments. The

vertical beams can also be steered.

Figure 1 illustrates the vertical, acoustical center points for

the three CAL models, from which the beams emanate. The

acoustical center points also represent the axis for beam

steering.

NOTE: For the acoustical center points of split

beam configurations, see “Split Beams” on

page 21.
