2. Make sure the frame of the speaker is firmly screwed onto the face. The frame prevents
the speaker from slipping all the way into the hole. Refer to Figure 17 on page 15 if you
need to reverse the frame to orient the Bose logo on the rectangular speaker face.
3. Push the speaker into the hole until the face is straight and flush with the wall
(Figure 22b).

CAUTION: If you use a screw gun to tighten any screws, first select the gun’s lowest torque set-
ting (do not exceed 2-4 inch-pounds or 0.2-0.5 N-m of torque). If the screw does not seat prop-
erly, finish installing the screw at the next highest torque setting, or by hand.
When the speaker is positioned inside the hole with the face straight and flat against the wall,
you are ready to tighten the dogleg clamp screws, labeled WALL, along the sides of the
frame. The dogleg screws exert pressure from inside to hold the speaker firmly against the
wall. Do not confuse the dogleg screws with those labeled GRILLE, which hold the frame.
CAUTION:
Although they should be thoroughly screwed down, be sure not to overtighten the
dogleg screws. Too much compression can crush the wallboard, making it crumble. This creates
uneven surface support and can leave gaps between the speaker face and the wall.
1. Slightly tighten the four dogleg clamp screws (Figure 23) until each one begins to grip.
This is caused by the clamps that swing out and press against the back of the wallboard.
2. With your fingers grasping the frame of the speaker, rock it slightly back and forth into
position. Check for even seating of the face before you tighten the screws any further,
and adjust the speaker if it needs to be straightened.

3. When the speaker is straight, tighten each screw.
