SPEAKER PLACEMENT
Polk Audio LC
FX Surround Loudspeakers give you
nearly endless placement options. But remember
that where you place your surround speakers
requires some careful thought, as installation
requires that you cut a hole in your wall or ceiling.
Left/Right Orientation: LC
FX Surround Speakers
have a left/right orientation, and each speaker is
clearly marked on its baffle for installation on either
the right or left. Right and left are defined from
your listening area as you face your system’s
center channel.
Directing the Driver (LC80
FX)
The fixed 15° angled driver in the LC80
FX allows you
to direct the midrange towards your listening area
when used for front stage (left-center-right). When
used as rear surrounds or as 6.1 or 7.1 back speakers,
direct the driver towards the listening area for a more
direct sound field or toward a wall for a more diffuse
sound field.
IMAGING
Solid/Diffuse Switch (LC65
FX/LC80FX)
LC
FX Surround Loudspeakers offer switchable “Solid”
and “Diffuse” imaging patterns to create the surround
effect you desire.
A “Diffuse” image is defined as one which creates
a “cloud” of sound; think of the effect as ambient
sounds which fill the environment all around you.
A “Solid” image is one which creates a more pin-
point sound; sound is more directional and localized.
Ultimately you are the best judge of what kind of
surround imaging you prefer.
The schematic drawing of the room represents an
ideal placement for all speakers in either a 6.1 or
7.1 speaker system.
