Suspending Plasma P1 Speaker Systems
P1 enclosures have L-track located on the top, bottom, and on one side. Single or double stud
ring fittings can be attached to the L-track to be used as suspension points. These points are
located at the center of gravity to allow the system to hang straight when used either vertically, or
horizontally. Plasma P1 is NOT designed to be suspended vertically from one another. More than
one system should never be suspended from a single point! Working load limits for the enclosure,
and fittings are shown below in Figure 5. Plasma P1 enclosures have been pull tested and
exceed a safety factor of 10 to 1.
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
damaged components, which could reduce enclosure strength. Inspect the track and 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 recommended load for the Plasma
systems.
