Groundstacking Configuration
WARNING: Suspending any object is potentially dangerous and should only be attempted by individuals who have a
thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice® strongly
recommends that all speakers be suspended taking into account all current national, federal, state and local regulations.
It is the responsibility of the installer to ensure that all speakers are safely installed in accordance with all such
regulations. If Phoenix speakers are suspended, Electro-Voice® strongly recommends that the system be inspected at
least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately. Any
hardware used to suspend a Phoenix speaker that is not associated with Electro-Voice® is the responsibility of others.

Ground Stack:
When using multiple
Electro-Voice® Phoenix speakers
in a ground stack configuration, the feet of each
enclosure is designed to fit into grooves of the enclosure
below it. This is both for the safety of the ground stack
and serves as an alignment for properly arraying multiple
loudspeakers. Always check that the feet are resting in
the grooves when using multiple speakers (Figure 1).
Unless you can safely lift the weight of the loudspeaker
on to the ground stack, have another person to help you
place it. The ground stack should be placed on a solid,
level surface. When using subs on a surface that is hard
or slick, use a piece of carpet or other material between
the feet and supporting surface to prevent the subs (and
stacks) from “walking”. When using a ground stack in
windy outdoor conditions, when the surface is slippery, or
when in adverse conditions, Electro-Voice®
recommends using a ratchet strap to secure the
speakers. For

Stand Mount:
The Electro-Voice® PX1122M and PX1152M include 1-3/8" stand mounts for use with tripod stands. Check the
specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker. Place the speaker
stand on a flat, stable surface and be sure to fully extend the legs of the stand. Do not try to make the stand “taller” and
compromise its structural integrity. Do not attempt to suspend more than one speaker on a stand designed for a single
speaker. Unless you are confident that you can safely handle lifting the weight of the speaker onto the stand, ask another
person to help you place it. Route cables and position the stand so that performers, production crew and audience
members will not trip over the stand or cables and pull the speaker system over. Secure the cables with wire ties or tape
whenever possible.
