X12-125F-GRID grid
The X12-125F-GRID grid is appropriate for arrays where extreme up or down angles are not
required. It is rated for a maximum hang of up to 18 X12-125F subwoofers in a single column.
Use the line array configuration software to determine the number of subwoofers needed to
achieve the desired acoustical coverage in the venue at a safe working load.
X12-125F-GRID grid includes two spreader bars and two side arms. Each spreader bar has
four 0.84-inch (21.4 mm) holes through it for use as attachment points. The center hole on the
bar labeled PICK HERE is used for suspending up to nine X12-125F systems using a single
point hang. This hole is on center of the spreader bar and on the center of gravity of the
X12-125F subwoofer. For suspending more than nine X12-125F systems, the user must use a
bridle from the two holes at the ends of the spreader bar.

The hole labeled SAFETY HERE is for attachment of a safety line if required by local
regulations. If used, ensure there is minimal slack in the safety line but it is not so tight as to
interfere with the vertical alignment of the array hanging from the pick point. The two outer
holes may be used for lifting as a two-point lateral hang, often useful to prevent twisting of the
array. In this situation, lifting and suspension lines must not exceed 15° from vertical and both
points must be lifted equally so the array is never more than ±5° from horizontal during the
lift.
Warning!
The spreader bar holes labeled PICK HERE and SAFETY HERE are not valid for any X12-125F
subwoofer array exceeding nine elements, even if two spreader bars are used. For arrays in
excess of nine elements, the two outer-most holes of the spreader bar must be used in a
!
bridled end pick configuration, regardless of whether one or two bars are being used.
Failure to heed this warning may result in extensive property damage, serious injury or death.
Consult the line array configuration software and follow all warnings, limitations, and
restrictions recommended by the software.
Warning!
Do not lift an array by attaching directly to the sidearms. Lift with the supplied spreader
!
bar(s) only.
Failure to heed this warning may result in extensive property damage, serious injury or death.
The X12-125F grid side arms are usually attached with the excess overhang at the rear to allow
for greater down-angle possibilities. For situations where more up-angle is possibly required,
such as covering a high balcony in a theater, the grid can be reversed with the excess grid
length overhanging the front of the array.
