5.0 EVF and EVH Rigging System
5.1 Introduction
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.

being connected, due to asymmetry of the plates.
