ADJUSTING THE TWEETER
Aiming the tweeter toward your listening position
improves imaging and detail. If you are using LC
i
Series In-wall Loudspeakers as front/main home the-
ater speakers, aim the tweeter toward your listening
position. For rear/surround speakers installed in walls
or ceilings, aim the tweeter toward the nearest reflect-
ing surface (an adjacent wall or ceiling) if you desire a
more diffuse sound field. For more direct sound, aim the
tweeters at your listening position).
Important Note:
LC
i
Series In-wall Loudspeakers are
not magnetically shielded and should not be placed
closer than 1’ (30cm) from a direct-view television or
video monitor.
Room Environment Controls
3dB Tweeter Toggle
If your listening room is very reflective, with smooth
sheetrock walls, hardwood floors, and non-cushioned
furniture, the sound will be overly “bright” and unnatu-
ral. Engaging the LC
i
tweeter attenuation feature (by
selecting the “cut” setting) compensates for the effect
of reflectivity in a hard room. Tweeter attenuation flat-
tens room response, without hindering higher frequency
response, for warmer, more realistic sound and more
accurate imaging.
Wall Distance Toggle
In-wall loudspeakers excel when placed more than 2’
(60cm) from side walls. If position limitations demand
that your loudspeakers be installed closer than 2’
(60cm) from side walls, the close proximity of the sur-
face can result in a response “bump” between 50 and
200Hz. This can cause in-wall speakers to sound
“boomy.” The distance toggle switch flattens response
and tunes out “boominess” without sacrificing deep
bass response, for more lifelike sound. If the speaker
is closer than 2’ to a wall, engage the wall distance
toggle (“Wall Dist.”) to match the <2’ setting.
Recommended speaker distance from side walls
is 2 feet (60cm).
