LEFT AND RIGHT SPEAKER PLACEMENT
The ideal mounting height for the LCR speakers is 38 to 42 inches
from the floor to the center of the speaker baffle . This height
corresponds to the height of your ear when you are sitting on a couch
or in a chair.
Use the chart below to determine the placement height of the
speakers. As part of the THX Ultra II approval process the LCR
speakers have very broad vertical dispersion, approximately +/-10
degrees.
The left and right speakers should be separated from 6 to 10 feet
apart center to center. If the speakers are separated too far apart the
sound will seem to come from each front speaker. If the speakers are
placed too close together the sound will seem too congested around
the television.
Note: The Ultra II LCR can be placed horizontally. When
placing the speaker horizontal the midrange / tweeter plate
should be rotated 90 degrees to maintain proper dispersion.
CENTER CHANNEL SPEAKER PLACEMENT
If possible, locate the center channel in you home theater system the
same height as your left and right speakers (38 to 42 inches from the
floor). If you must place the speaker above or below a television, we
recommend placing the speaker no more than 2 feet above or below
the center of the left and right speakers.
Note: The Sonance Cinema Ultra II LCR speakers are
magnetically shielded to eliminate interference with TV's, or
other electrical devices.
