CONFIGURATION F
When an array is lifted with a separate motor attached
to each of the MTG-3D corner lifting points, as shown in
Figure 39, an array of up to 16 M3Ds can be supported
(see Table 12).
Each motor hook may be attached to the corner of the
MTG-3D Top Grid with two 5/8-inch or 3/4-inch shackles.
There is a maximum combination of 16 M3D and M3D-
Sub or other loudspeakers, such as MSL4s and CQs,
which can be underhung in this configuration. The total
weight of the hung system cannot exceed the total
equivalent weight of 16 M3Ds.
NOTE: Each pair of motors must be rated to
support the total weight of the entire array.
