5.0 EVF and EVH Rigging System (cont’)

5.213 All-Eyebolt Clusters

A basic two-cabinet flying system is shown in Figures 19 and 20, illustrating the components necessary to make a typical two-system horizontal or vertical cluster using M10 eyebolts. Secure cabinets to the building structure with user-supplied hardware. All user-supplied hardware, shackles, wire rope, bolt con- nectors, etc., must be rated for overhead lifting. Refer to section 1 for suspension point locations.

A second enclosure may be suspended from the first by using the same M10 rigging points on the second enclosure. Connection between the two enclosures through the M10 eyebolts requires hardware sup- plied by the end user. All user-supplied hardware must be rated for overhead lifting. The angle between the two enclosures as well as the angle between the first enclosure and the structure can be controlled by the length of the user-supplied hardware. If the desired angle cannot be achieved by varying the length of this hardware, then pull-back points can be used. It is recommended that both the top and the second box use a pull back. The pull back can be achieved with the use of additional M10 eyebolts at the back of the enclosures. The hardware used to achieve the pull back is supplied by the end user.

A maximum of two enclosures is allowed with all-eyebolt clusters.

A minimum of two eyebolts are required for suspension of all-eyebolt clusters.

Electro-Voice is renowned for its high-quality audio solutions, and the EVF series embodies this commitment. The EVF-2121S, EVF-1121S, EVF-1181S, EVF-1151S, and EVF-2151D are a collection of loudspeakers designed for a variety of professional audio applications, each with its distinctive features and capabilities that cater to different sound reinforcement needs.

The EVF-2121S is a dual-12-inch full-range speaker that combines exceptional power handling with a wide frequency response. It utilizes a coaxial driver arrangement, providing even sound distribution and a cohesive audio experience. This model is ideal for medium to large venues, offering a robust SPL (sound pressure level) output and clear reproduction of vocals and instruments.

In contrast, the EVF-1121S features a single 12-inch driver, delivering precise, high-impact sound suitable for smaller spaces. Its design emphasizes clarity and detail, making it perfect for live sound applications. The compact and lightweight design also ensures ease of transport and installation, appealing to mobile sound reinforcement professionals.

The EVF-1181S is a dedicated subwoofer that amplifies low frequencies, featuring an 18-inch woofer for deep, powerful bass response. Its extended low-frequency output enhances the overall sound experience, making it an ideal choice for high-energy music events and professional club environments. Designed with rugged construction and efficient power handling, the EVF-1181S is built to withstand demanding conditions while delivering reliable performance.

The EVF-1151S combines a 15-inch woofer with an advanced high-frequency driver for a full-range sound that works well in theatres, concert halls, and corporate events. The speaker ensures clear mid and high frequencies, maintaining vocal intelligibility even in challenging acoustic environments.

Lastly, the EVF-2151D is a dual 15-inch subwoofer that enhances overall system performance with its ability to produce deep bass. Its compact enclosure design allows for seamless integration into various sound setups, ensuring it can meet the needs of both portable and installed sound systems.

All models in the EVF series incorporate advanced technologies, including proprietary transducers and custom-engineered waveguides, which contribute to their impressive performance. With features like durable enclosures and efficient power handling, these loudspeakers are engineered to provide reliable sound reinforcement for both live and recorded applications. Whether it’s a concert, event, or installation project, the Electro-Voice EVF series stands out for its versatility and audio excellence.
