Electro-Voice® Zx3 Owner’s Manual
Suspending Zx3 Speaker Systems
Zx3 enclosures have 4 steel anchor points internally mounted on the top and bottom. Single stud fittings
can be attached to these anchor plates and used as suspension points. Each of these anchor plates also
has a M8 thread to accept rated forged M8 shoulder eyebolts. In addition to these points there are three
additional M8 threaded points; two on the handle side, and one on the rear. These points can be used
for suspending Zx3s vertically, horizontally, individually, in clusters, or to attach to EV mounting brackets.
Working load limits for the Zx3 and fittings are shown in Figure 2.

Prior to each use, inspect the grid assembly or suspension point(s)
and associated hardware for any cracks, deformations, broken welds,
corrosion, missing or damaged components which could reduce the
grid assembly or suspension point(s) strength. Replace any damaged
hardware. Never exceed the limitations or maximum recommended
load intended for grid assembly design or suspension point(s). As an
added safety measure, it is suggested that the user install a second
suspension point back to the grid (or building structural supports).
This redundant safety point should have as little slack as possible
(less than one inch is preferable). Prior to each use, inspect the
loudspeaker enclosures for any cracks, deformations, missing or dam-
aged components, which could reduce enclosure strength. Inspect
the bracket assembly on the enclosures for any cracks, deformations,
missing or loose screws which could reduce the flying hardware
strength. Replace any loudspeaker systems that are damaged or
missing hardware. Never exceed the limitations or maximum recom-
mended load for the Zx3 systems.
Zx3 M8 Suspension Points
Metric (M8) inserts are equipped on the top and bottom of the enclosure, around the handle, and on the
back of the enclosure for a total of 7 points. The inserts can be used to attach forged eyebolts or rigging
brackets.
