Ground Stack
Stand-alone loudspeakers can also be stacked when used with the Array Frame and Stack Adapter Kits (not included, sold separately).
Preparing an Array Frame and Stack Adapter Kit for a Ground Stack
1. Adhere the adhesive sides of the Bumper Pads to the bottom of the
Array Frame as shown.
2. Secure the Array Frame to the surface where the ground stack is to be
deployed, using fasteners or other suitable hardware (not included)
for the location of deployment.
WARNING!: The Array Frame MUST be secured to the
surface where the ground stack is deployed to prevent
unintended tipping.
NOTE: Before deploying the complete ground stack, make
sure the Array Frame is adequately placed on a flat, solid
surface. Make sure the ground stack cannot slip or slide due
to sound vibrations or other disturbances, such as people
pushing/pulling the stack.
3. Attach the front end of each Angle Arm (part of the Stack Adapter Kit, sold separately) to each side of the Array Frame. Secure
each side with the Angle Arm Rigging Pins.
4. Adjust the Angle Arms to the desired angle. Secure each with the Array Frame Rigging Pins.
