EVOi.324 Coverage Angles

Placing this 80° x 80° speaker up in the air and pointing it towards an audience area will result in a defined area of coverage.

Optimized Coverage Reduced Loudness

Note that this area of coverage actually includes three different areas: an area of “optimized coverage” (black); an area of “reduced loudness” (gray); and an area “out of coverage” (white).

Understanding the optimum performance of the EVO Loudspeaker through the use of a simple Throw Ratio and Aiming guide line will help you achieve optimized coverage over your defined listening area.

The Throw Ratio

Based on its area of coverage performance, the EVOi.324 has a height-to-depth Throw Ratio of 1:3. This Throw Ratio can be used to optimally position the loudspeaker. For example, if the EVOi.324 is installed at a height of 10’, it will “throw” to a distance of 30’ away from the loud- speaker and hence provide optimized coverage up to 30’ away.

Refer to Table 1 and Figure 11 below to identify either:

i.The throw (optimized coverage distance), for a given fixed (pre-determined) height above the floor.

ii.The installation height necessary to provide the desired throw (optimized coverage distance).

		Aiming Point	Downward
	Installation	(Distance from	Tilt Aiming
Throw *	Height	Loudspeaker)	Angle
30'	10'	20'	26.6°
40'	13' 4"	26' 8"	26.6°
50'	16' 8"	33' 4"	26.6°
60'	20'	40'	26.6°
70'	23' 4"	46' 8"	26.6°
80'	28' 8"	53' 4"	26.6°
90'	30'	60'	26.6°
100'	33' 4"	66' 8"	26.6°
110'	36' 8"	73' 4"	26.6°
120'	40'	80'	26.6°
