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.
