4.3.2 Ground Stacking
StudioLive AI-series full-range loudspeakers have four nonskid rubber feet on the
bottom for upright front-of-house use and four nonskid rubber feet on one side for
stage-monitor applications.
If your application is primarily portable, PreSonus loudspeakers can be easily
ground stacked and configured for a variety of venues. When ground stacking,
make sure all speakers are securely anchored to the floor using load straps or other
anchors. Rubber mats can also be utilized between cabinets to prevent boxes from
“walking.” This is particularly important if the speakers are accessible to the public.
Check that the surface the speakers are to be stacked on is level, even, and has
sufficient structural integrity to support the speakers. If ground stacking on a
portable stage, make sure you know what is directly below the speaker stack.
WARNING: Placement on improper or unstable surfaces could cause the
loudspeaker to topple, which could result in serious injury or death.
4.3.3 Pole Mount
All full-range StudioLive loudspeakers are equipped with 35 mm pole socket
that allows the speaker to be mounted on a speaker stand or on a pole over
an 18sAI subwoofer. This pole socket allows for straight 90˚ vertical mounting
or for tilting the full-range loudspeaker down 10˚ while on a pole.
When using a tripod speaker stand, extend the legs to provide the
most stable support to the speaker so that it cannot be tipped over. It
is highly recommended that tripod stands be placed away from foot
traffic. If the stands are to be used outdoors, theatrical sand bags may be
placed on the legs to provide some protection against wind load.
StudioLive AI-series full-range loudspeakers can be mounted on top of a StudioLive
18sAI subwoofer using the optional SP1BK threaded subwoofer pole. This 31.5-inch
pole is designed to secure the 18sAI subwoofer and has been pull- and tilt-tested for
safety with all three full-range StudioLive AI-series loudspeakers.
WARNING: Do not substitute a longer pole from a third-party supplier. Use of
a longer pole than specified could cause instability, which in turn could result
in serious injury or death.
WARNING: StudioLive AI-series loudspeakers weigh a minimum of 51 lbs
(23.1 kg). Use proper lifting techniques and safety precautions when
mounting an AI-series loudspeaker on a SP1BK subwoofer pole or speaker stand.
When mounting atop a speaker stand, verify that it is rated to support the weight of
your StudioLive AI-series loudspeaker. The weight of each model can be found in
Section 5.1.
