EVO Sound System Design Basics
The primary function of a sound reinforcement system is to make sure that all of the listeners in a given audience area are
able to understand the speech and/or lyrics that are being reinforced. The intelligibility of a loudspeaker system is a measure
of how “understandable” its output is. Intelligibility is optimized when the sound radiated from the loudspeaker is primarily
directed to the audience areas and away from microphones and reflective surfaces in the room.
In order to ensure that the radiated sound is directed primarily to the audience areas, great care must be taken in deciding on
loudspeaker placement and aiming. Understanding a loudspeaker’s coverage angles and the proper application of those
coverage angles is the first step towards designing a great sound reinforcement system.
EVOi.324 Coverage Angles
The majority of the sound coming from the EVOi.324 loudspeaker radiates at an angle of 80 degrees in the speaker’s
horizontal (side-to-side) plane and 80 degrees in the speaker’s vertical (top-to-bottom) plane. (Figures 8 and 9.)
