ers be mounted closer than 2' (60cm) from side walls or ceiling,
the proximity of the surface can result in a response “bump”
between 50 and 200Hz. This can cause the loudspeakers to
sound “boomy.” The “Wall Distance” switch flattens response
and eliminates “boominess” without sacrificing deep bass
response for more lifelike sound. Set the switch accordingly,
<2' (60 cm) or >2' (60 cm).

Prior to installation, hold the speaker in the chosen location,
6 to 8 feet off the floor, to make sure it safely clears obstacles
such as ceiling, adjacent walls, corners, beams, lighting fixtures
and door/window frames.
Using the keyhole slots in the bracket template (included),
mark the installation location of the two keyhole slots with
a pencil. Orient the template so that the small ends of the
keyhole slots are facing “up.”
1.
If you are certain that there is a stud behind the
wall surface, drive a screw (not included) capable
of supporting the loudspeaker’s weight through
the wall and into the stud.
2. If there is no stud behind the wall at the chosen
location, install a wall anchor (not included) capable
of supporting the loudspeaker’s weight into the wall
by following the wall-anchor-manufacturer’s instructions.
3. For masonry walls, use a masonry drill bit and
#10 masonry anchor and screw (not included).
4. Tighten screws into stud or wall anchors, leaving
screw heads protruding 1/4" (6mm).
5.
Make all wire attachments now.
6. Line up the keyhole slots on the back of the speakers
so that the screw heads pass through the large center
hole of the slots.
7. Let the speaker slide straight down, allowing the screw
head to slip behind the smaller end of the keyhole slot.
8.
Tug gently on the speaker to make certain that the
screws and bracket are properly aligned and that
the wall anchors are secure.
9. If the bracket is not held snug against the wall by the
screw heads, remove the speaker from the wall, drive
the screws in a little further and then remount the speaker.
