EVI Speakers Provide Sound Solution for OKC High School Gym

March 17th, 2008



“This is a typically reverberant gymnasium,“ says Hal Swinhart of Cox Systems Technologies, “precisely the kind of space in which the EVI series excels. The school rearranged the room to accommodate more people in the stands, so it was time to bring in improved coverage and intelligibility. We installed four EVI-15 two way enclosures in the main gym, along with a single EV SB122 sub, flown in an exploded central cluster. The installation has a small footprint in relation to the output and coverage it provides, and gives significantly clearer and more controlled sound for both announcements and music. The school loves their new system.“

In addition to the EVI-15 mains, (3) CPS2 and (1) CPS1 amplifiers provide plenty of power to the system, (2) MA1212 120W mixer amplifiers ensure easy-to-use-flexibility for paging and playback duties, and loudspeaker performance is optimized via presets on a Dx38 processor. The EV spec extends to the wrestling room, where a central cluster of (4) EVID 4.2 speakers, mounted using EV hardware, provides omni-directional coverage.

About Electro-Voice EVI loudspeakers

Electro-Voice’s unique EVI Vari Intense® (VI) speakers are engineered to eliminate the need for additional long-throw horns or delayed sources in many rooms. The EVI Vari Intense® series provides an economical solution for permanent installations that require coverage over a rectangular area. In a typical room, the distance from the loudspeaker to the last row is two or more times that to the front row, resulting in a substantial loss in level and intelligibility at the rear.

The VI horn delivers 6 to 8 dB more SPL to the back of the room, overcoming the level loss without resorting to the expense and complexity of additional speaker systems or components. The problem is old; EV’s solution is new. EVI is perfect for conference centers, houses of worship, halls, and other venues where evenly distributed SPL is essential. A simple 3-2-1 rule-of-thumb applies for determining EVI coverage patterns: The pattern’s width will equal twice the height of the room, and the pattern’s length will equal three times the height.
