– For extreme down angles, attach a second EVA-EG2 grid at the bottom of the array for
use as a pull-up point, as long as the maximum pull angle between suspension lines does
not exceed 60°.
When flying five or more EVA-2151D modules:
– Use only the two outermost attachment holes on the spreader bar.
– If using two spreader bars, use the two outermost attachment holes on each bar.
– You are allowed to use a maximum vertical column of eight modules, if the column is kept
perpendicular to the ground.
– The maximum suspended column weight in a stand-alone subwoofer array with 0° of
inclination (tilt) angle using both outer attachment points on the spreader bar is 1,470lb
(667kg).
!
Warning!
Any array with more than four EVA-2151Ds must use the two outermost attachment holes on
the spreader bar.
!
Warning!
Never attempt to suspend EVA systems overhead by any other method than the use of EVA-
SG2, EVA-EG2 or EVA-CG (discontinued) grids and spreader bars, as outlined in this manual.
EVA-1151D modules (discontinued) may be suspended from inverted EVA-1151D tie plates
only with an EVA-GXB spreader bar (sold separately).
8.4 Simplified structural-rating guidelines
The simplified structural-rating guidelines for EVA loudspeakers were determined based on:
1. Vertical elevation possible with EVA-SG2, EVA-EG2 and EVA-CG (discontinued) grids.
2. Total weight of all enclosures in the array plus accessories, cabling and rigging.
3. Angled forces acting on rigging components and enclosures.
When applying the structural rating guidelines to any EVA loudspeaker system suspended
overhead:
1. Never exceed 720lb (327kg) total column weight of suspended EVA-1151D
(discontinued) and EVA-2082S loudspeakers, accessories and cabling (typically any
combination of eight EVA-2082S and/or EVA-1151D modules).
2. When flown in the same column with full-range modules from an EVA-SG2 or EVA-EG2
grid, subwoofers must always be at the top of the array with no splay between modules.
3. If using a second grid at the bottom of the array, the angle between the suspension lines
must never exceed 60°. Do not use EVA-CG (discontinued), EVA-EG or EVA-EG2 grids in
this application.
