Cam nut system:
Push the speaker into the mounting hole and begin
screwing the mounting screws in (clockwise). This will flip the cam nuts
outward into position to clamp to the drywall and mount the speaker
firmly
(figure 13)
.
Do not
tighten any one of the multiple cam nuts all
the way in the beginning. Tighten each screw about 1/3 of the way then
rotate to the next. This way you will visit each screw 3 times before you
snug it into place. If you tighten any single screw all the way into place
you have difficulty knowing how tight or how much further you have to
go on the remaining screws and it is possible to damage the cam nut
assembly if it is over-tightened.
When mounting SE-791D rectangular speakers, use the level to square
them up perfectly before you put the final tightening twist to the cam
nuts.
Clamp-ring system:
Insert the bottom edge of the clamp-ring into the
wall cavity so that the screws are touching the bottom of the opening.
Now slide the top edge of the clamp-ring into the opening. Once the ring
is inserted into the wall cavity, push the speaker frame into place against
the wallboard. Next, pull the screws out so that the metal ring is pulled
against the back side of the wallboard and tighten the first screw while
still holding one of the other screws before continuing to tighten the rest.
Once you have mounted your speakers, gently press the grille into the
recess. The grilles are held by “friction fit”. Grille retention gum is
provided in case this friction is insufficient. Put four pieces of the black
gum in the edge of the black baffle area of the plastic frame and seat the
grille into the gum.
