5.0EVF and EVH Rigging System

5.1Introduction

5.11 The Flying EV-Innovation (EV-I) Loudspeaker System

All EVH and EVF loudspeaker systems incorporate heavy-duty M10-1.5 threaded attachment points on each enclosure. These attachment points work in conjunction with (1) the M10 eyebolts included with each loudspeaker or (2) the optional VRK and HRK rigging kits. The rigging kits allow the user to rig multi- ple systems together in horizontal and vertical configurations. The horizontal and vertical rigging kits are an open-ended design, meaning that any system in the EVF and EVH families can rig to any other. The verti- cal and horizontal rigging plates give the user ultimate flexibility for splay angles from 0° to 45° degrees

in 5° increments (0° to 20° for EVF to EVF subwoofer). This system was designed to allow the end user to construct a loudspeaker cluster to fit nearly any application. Figure 13 and Table 4 show the possible connections using the three VRK and HRK rigging kits to connect any EVF or EVH loudspeaker.

Plates may need to be flipped depending on which side is

being connected, due to asymmetry of the plates.
