Variable Intensity 1-Box Sound Reinforcement System

EVI provides a simple, economical solution for permanent installations requiring even coverage over a fixed rectangular area. In a typical room, the distance from a front-mounted loudspeaker to the last row is two or more times the distance to the front row, resulting in a substantial front-to-back difference in level and intelligibility. The Variable Intensity horn counters this problem by increasing the sound sent to the back of the room by six to eight dB, balancing SPL distribution without the expense and complexity of additional systems or components.
