an idea on how the same auditorium floor plan could be easily covered in a surround-style arrangement with just two EVI systems per side rather than four distributed arrays. Although not providing the high- est intelligibility or smoothest response, it is appli- cable to cinemas and some musical preferences. This has the advantages of cutting installation time, amplifier channels, additional delay lines and at the same time providing superior coverage.

A gymnasium is another perfect application for the EVI systems, covering each grandstand from a pair of centrally located EVI systems (see Figure 8). In addition, you can cover the entire gymna- sium from either a single lengthwise-oriented sys- tem or with a pair of widthwise-spaced systems with lower-SPL coverage on the floor of the gymnasium than in the stands, so the players are not disturbed by announcements (see Figure 9).

When the EVI-12 and EVI-15 systems are tilted up approximately 15°, their coverage pattern lengthens to match a level EVI-28 at 5 times the height. In such cases the systems work very well to

replace a distributed system along a very long, fairly wide corridor where very high SPLs are not required on a continuous basis (such as an airport concourse with 15 to 20 foot ceilings, where a speaker would be placed about every 75 feet). See Figure 10 for approximate mounting locations and floorplan coverage.

These are but a few of the widely varied applications where the new EVI-12, EVI-15 and EVI-28 systems will easily outperform a conven- tional system. The extremely uniform coverage of the systems are fairly insensitive to placement, re- quire only a few simple calculations to find the best mounting location, and the aiming angle is no more or less sensitive than a conventional loudspeaker. This makes installation nearly foolproof. Even installation in non-optimal conditions will produce remarkably even coverage and high intelligibility.

All plots depict the intended listening areas only, and do not include the “offset distance” to the first row. For example, the first set of plots on figure 3 depict the same 54’ x 36’ area as figure 1. See notes on simulation software.

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.
