3.3 Simplified Structural-Rating Guidelines
Electro-Voice engineers have defined a set of simplified structural-rating guidelines that will en-
able a rigger to immediately evaluate the safety of an XLVC system on site without having to
make complex force-distribution calculations. A combination of destructive testing and computer
modeling were used to analyze the complex forces throughout arrays. Conservative working-load
ratings were utilized to simplify the guidelines. Therefore, array configurations other than those
illustrated in these simplified guidelines may be permissible. For those applications, consult
section 3.4, Complex Structural-Rating Analysis for a detailed structural analysis.

The simplified structural-rating guidelines for the XLVC loudspeakers are shown in Figure 13.
These guidelines provide a simplified rating for typical arrays based on the:

1. Vertical elevation angle of each enclosure.
2. Total weight of that enclosure plus all the enclosures and rigging hung below it.
3. Angled forces on rigging frames, rigging components and enclosures.

The XLD281, XLE181 and XS212 loudspeaker systems each have their own simplified structural
rating guidelines. The XLD281 ratings are shown in Figure 13a, the XLE181 in Figure 13b and the
XS212 in Figure 13c.
