Measure the vertical spacing “H” required between wall brackets at the
location of the speaker to be installed. Mark the holes for wall plug drillings.
Drill holes to the wall to insert the wall plugs. We recommend using 2 wall
plugs for each bracket to ensure they are securely attached to the wall.
Install the wall plugs accordingly.
