XLE GRID
The XLE GRID is a grid used for suspending a column of XLE181 loudspeaker systems overhead and is shown in Figure 5b. The XLE GRID sidearms are identical to that of the XLD GRID. However, the XLE GRID spreader bars are shorter to match the width of the XLE181 loudspeaker system rigging.

CBEAM
The CBEAM, shown in Figure 5c, has two functions. It may be used a coupler beam to enable a column of XS212 systems to be hung behind a either a column of XLD281 loudspeaker systems or a column of XLE181 systems. The XLD GRID and XLE GRID grids are used to attach a column of loudspeakers to the CBEAM. The CBEAM may also be used as an extender beam to hang a single column of loudspeaker systems overhead (either XLD281 or XLE181). As an extender beam, the CBEAM allows a single pickup point that is beyond the end of either the XLD GRID or the XLE GRID, enabling the entire array to be tilted downward at greater angles, eliminating the need to use a pull back from the bottom of the column. The CBEAM may also be reversed to enable greater upward angles for the loudspeaker column.
Two yoke assemblies are used to attach each grid (either XLD GRID or XLE GRID) to the CBEAM. Each yoke is fastened the two spreader bars from the grids.
When two hoist motors are used to suspend a CBEAM overhead, the two motors are attached to the front and back of the CBEAM. In this case, the hoist motors are used to adjust the vertical angle of the CBEAM and the array underneath. When one hoist motor is used, the vertical angle of the CBEAM and the array underneath is determined by the
