DIMENSIONS - LCR

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.

SURROUND SPEAKER PLACEMENT

The ideal mounting height for the Cinema Ultra II SUR speakers is 24
to 36 inches above the height of your ear when you are seated. This
would place the speaker from 60" - 80" from the floor to the center of
the speaker baffle .

The Cinema Ultra II SUR speakers should be placed directly to the left
and right of the listening area, as shown below.

Another option is to mount the surround speakers in the ceiling. When
the speakers are installed in the ceiling the speakers should be placed
to the left and right sides of the listening position and separated 8 to
10 feet apart.

Note: The Cinema Ultra II SUR can be placed horizontally.
When placing the speaker horizontal the midrange /
tweeter plate should be rotated 90 degrees to maintain
proper coverage.

MOUNTING OPTIONS

New Construction

The Cinema Ultra II series speakers feature an integral RotolockJ
mounting system for quick mounting into walls. The Cinema Ultra II
series FlexBracket is only necessary in new construction installations
when reserving a location for the speaker is desired.

60" - 80"

SURROUND BACK SPEAKER PLACEMENT

The back speakers in a 6.1 or 7.1 system should be installed on the
rear wall of the listening room at the same height as the left and right
surround speaker.

If your system will primarily be used for multi-channel music we
recommend the use of one or two additional LCR speakers for the
back surround channel. If you will be playing mostly movies the use of
one or two additional Cinema Ultra II SUR speakers is recommended.

The FlexBracket will serve as a guide for the dry wall installer when
cutting holes for in-wall speakers. The FlexBracket should be nailed or
screwed to the studs so that the hole is in the desired location once
the drywall is installed.

Retrofit

With the Rotolock system, the speaker can be installed directly into
existing walls. Once the hole is cut and the cable is run, the speakers
can be installed in a matter of seconds.

Once you have determined the area you would like to locate your
speakers, you will need to do an obstruction survey. Before you cut
the hole for the speaker, be certain no studs, conduit, pipe, heating
duct or air return will interfere with the speaker.

The cutout for the Cinema Ultra II series is 10-1/4 (260mm) x 18-3/4"
(476mm). There must also be 3-15/16" of depth within the wall for the
speaker.

60" - 80"

A cut out template is provided in the packaging of the speaker.
Position the template where the speaker is to be located and pencil an
outline on the wall. If you are unsure about obstructions, drill a small
hole in the center of the cutout and insert a coat hanger into the hole
to feel for possible obstructions. If no obstructions are found,
proceed with cutting the hole using a drywall saw and run the speaker
wires.
