Rectangular coverage pattern | Electro-Voice EVI-12, EVI-15, EVI-28

Welcome to the world of Vari Intense® horn technology from Electro-Voice. This Applications Guide is not intended as a “very intense” descrip- tion of installation procedures, but more as a partial description of applications and a discussion with the designer to help you understand this revolution- ary technology and use the Electro-Voice Vari In- tense® systems to install better-sounding systems and significantly reduce time and material costs.

In a nutshell, here are the major advantages of the new EVI systems:

• Rectangular coverage pattern.

Traditional horns deliver an elliptical pattern to the floor. VI horns deliver a rectangular pattern, which helps to fill in the corners of the room. No more costly delay lines or cheap seats!!

• Even SPL front-to-back.

The unique, patented throat and flare struc- ture of the VI horn delivers a 6-10 dB hotter signal to the rear of the room, eliminating ear- strain at the back of the seating area and pain- ful ears at the front.

• Greater Intelligibility.

VI horns deliver sound to fill only the floorplan, providing uniform direct-field SPL and an order of magnitude less energy into the reverberant field. This provides an increase in mid- to high-frequency intelligibility of 6 dB in most applications.

• One horn replaces two.

With VI technology we’ve eliminated the de- structive interference which occurs between long- and short-throw horns. We’ve also elimi- nated the cost of a properly designed two-horn system which must include another power am- plifier channel for good power control and impedance matching.

• Labor savings in the box.

With structural rigging from the factory, these systems will fly more conveniently and in less time than many competitive products. In addi- tion, less time is spent on the aiming and repo- sitioning that is required with traditional long- throw/short-throw horn combinations. This will save you additional money.

EVI-12, EVI-15, EVI-28 specifications

The Electro-Voice EVI series of loudspeakers, including the EVI-12, EVI-15, and EVI-28, represents a class of high-performance sound reinforcement solutions designed for various applications, ranging from live sound to permanent installations. These speakers are known for their reliability, sound quality, and advanced acoustic technologies.

The EVI-12 is a compact, high-intelligibility loudspeaker equipped with a 12-inch woofer and a 1-inch high-frequency driver. It features a unique, rotatable horn design that allows for precise control over the coverage pattern, ensuring that sound is evenly distributed across the listening area. This makes the EVI-12 an excellent choice for venues with challenging acoustics, such as auditoriums and conference rooms. Additionally, its lightweight construction facilitates easy installation and portability.

Moving to the EVI-15, this model employs a 15-inch woofer and a similar high-frequency driver. The larger woofer provides extended low-frequency response, making it suitable for larger venues or situations where deeper bass is required. The EVI-15 incorporates advanced DSP technologies, allowing for enhanced performance tuning and system integration with other Electro-Voice products. Its robust cabinet design ensures durability while minimizing unwanted resonance, resulting in clean and powerful sound reproduction.

At the top of the EVI line is the EVI-28, a versatile dual 8-inch loudspeaker solution designed for high-performance applications. The EVI-28 is engineered with dual 8-inch woofers, which deliver exceptional clarity and detail across the frequency spectrum. This model is particularly effective in distributed sound reinforcement setups, where multiple speakers can be arrayed for wider coverage. The EVI-28 also features advanced waveguide technology to ensure consistent performance across various angles, resulting in superior directivity.

All three models in the EVI series are built with a focus on ease of use and integration. They include various mounting options and can easily adapt to any sound reinforcement system. The combination of high-quality components, innovative design, and attention to detail ensures that the EVI series delivers reliable performance for professionals in the audio industry. Whether it’s the EVI-12, EVI-15, or EVI-28, each speaker is engineered to meet the demands of modern sound reinforcement with clarity and power.
