A basic three-over-three cluster is shown in Figure 23.

Main suspension lines and pull backs must be tied to the tie plates.

Note that the HRK kits are designed to make weight-symmetrical clus- ters, i.e., those whose left-to-right center of gravity is in the center of the cluster.

The following components are needed to achieve this cluster:

1.Four HRK-2 horizontal rigging kits for EVF to EVF subwoofer/EVH.

2.User-supplied hardware to link the upper cluster to the lower cluster.

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.
