Once loudspeaker position has been decided, affix wall section of wall bracket (A, B, or C depending on Cuboid model) securely to a suitable wall mounting point.
Remove M8 fixing bolts from the rear of the loudspeaker cabinet.
Position loudspeaker cabinet section of wall bracket over the four M8 mounting points and secure with the four bolts from the back of the cabinet.
Optional wall bracket mounting positions enable greater down-tilt, using the lower four M8 bolt position, or the loudspeaker can be mounted in landscape mode by rotating the bracket as shown:
Lift loudspeaker into position making sure that the two halves of the wall bracket line up - the adjustable bolt sits into the two 'U shaped' cups in the wall section of the bracket.
Secure the assembly with the fixed bolt in the lower hole in the bracket - this provides the pivot for angling the loudspeaker. Adjust the grub screw to fix the down-tilt angle.
Once the loudspeaker is in position and you are happy with the angle adjustments, tighten all fixing as shown to lock the cabinet in place.
