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.

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).

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.
