3.0 Designing an EVF/EVH Cluster (cont’)

One clustering technique that accomplishes this separation without putting a physical space between two full-range systems is putting a low-frequency or subwoofer system between two full-range systems. Such a cluster is shown in Figure 9, assembled with the optional HRK rigging kits.
