ROOM ENVIRONMENT CONTROL
Wall Distance Switch
In-wall and in-ceiling loudspeakers excel when placed
more than 2' (60cm) from side walls. If position limita-
tions demand that in-wall loudspeakers be installed
closer than 2' (60cm) from side walls, the proximity of
the surface can result in a response "bump" between
50 and 200Hz. This can cause in-wall speakers to sound
"boomy." The Wall Distance Switch flattens response
and tunes out "boominess" without sacrificing deep
bass response, for more lifelike sound.
If placement is closer than 2' to a wall: Engage
the Wall Distance Switch ("Wall Dist.") to match the
<2' setting. Recommended speaker distance from
side walls is 2 feet (60cm).

PAINTING IN-WALL GRILLES
Painting in-wall grilles
The LC80
aluminum grille. The perforated aluminum grille
may be painted.
Required tools:
1. Paint of your choice (grilles must be spray painted).
2. A paperclip or corkscrew (for removing the
paintable grille).
3. Masking tape
4. Paint mask (supplied; covers un-paintable parts)
Preparation:
1. Separate the parts of the speaker. If the speaker
is not yet installed, the grille can be removed
simply by pushing the clamp screws forward
to push the grille off the speaker from the inside.
2. Remove the cloth scrim from the inside of the grille.
3. When painting the speaker frame, use the supplied
paint masks to carefully mask off the front of the
speakers to protect the drivers and baffles. You can
do this while the speaker is already installed in the
wall (if, for instance, you're repainting the room).
If you do not have the paint masks, carefully mask
the speaker components using paper and masking
tape. Use a paper clip to remove the grille.
Painting the aluminum mesh grille:
The grille of the LC i Series speaker features an even,
protective paint. This paint is an ideal primer.
1. Paint the grille.
Note: Grilles must be spray painted. Do not use
a brush and paint. Thick, brushed paint may clog
the grille holes. Use thin coats of spray paint.
If you're using a compressor and spray gun, use
the finest, most diffused setting. Be careful not
to fill the holes in the grille with paint.
2. When the paint is completely dry, press the white
cloth scrim into place and carefully reinstall the
grille by fitting it into its recess so that it is just
resting on the frame. Starting with one corner,
go around the speaker and push the grille into
the grille notch a little bit at a time. Be gentle;
the grille may be easily bent by rough handling.
You will feel a positive "snap" when the grille
is fully in place.
Painting the frame:
1. Apply paint to exposed (unmasked) parts. Use
two or more thin coats.
2. When the paint is completely dry, remove the
masking material.
