in new construction. Designed to be used with the RotoLock® mounting system.
Symphony Coverplate (part# 92093) — Covers the hole made by the
FlexBracket during construction until the speaker is installed.
SPEAKER PLACEMENT
Left and Right Channel Speakers
• Place the left & right channel speakers on either side of the video screen,
anywhere from 6 feet to 10 feet apart and 38 – 42 inches from the floor
(which corresponds to the height of your ears when you’re seated on a
couch or chair).
• If possible, locate the speakers at least 18 inches away from the side walls.
• The main listening position should be between 8 and 12 feet away from
the speakers.
Use Illustration 1 as a guide.
Center Channel Speaker
• If possible, locate the center
speaker at the same height as
the left & right speakers (38 –
40 inches from the floor).
• If you must place the center
speaker above or below a
video screen, we recommend
placing it no more than 2 feet
above or below the center of
the left and right speakers.
Keeping the speakers within
this 4-foot window will
maintain consistent tonality
between all 3 speakers.
Use Illustration 1 as a guide.
Left & Right Surround
Channel Speakers
The Cinema Select SUR speakers should be placed in the
walls directly to the sides of the
listening position, between 5
feet and 7 feet off the floor.
Use Illustration 2 as a guide.
If placing the speakers on the
walls directly to the sides of the
listening position isn’t possible,
you can mount them on the
ceiling. Locate the speakers
directly to the left and right
sides of the listening position,
between 6 feet and 10 feet
apart. Mount the speakers so
the tweeters aim at the screen
and rear wall, with the woofers
towards each other.
Use Illustration 3 as a guide.

Surround Back Channel Speakers
The surround back speakers in a 6.1- or 7.1-channel system should be
placed on the rear wall of the listening room at the same height as the left
and right surround speakers. Place the speakers from 4 feet to 8 feet
apart.
Use Illustration 4 as a guide.
WIRE GAUGE
Extra resistance in the speaker wire can make a speaker sound less
dynamic and reduce definition of the bass frequencies. In extreme cases,
it can even attenuate high frequencies. Also, amplifier power is wasted in
wire with extra resistance, reducing your system’s maximum output level.
To prevent degrading sound quality, the total wire resistance should be
less than 10% of the speaker’s impedance. This means that for 8-ohm
speakers like the Cinema Selects, the total resistance of the wire should
be less than 0.8 ohms.
Refer to the following table when selecting the proper wire gauge for
your system:
PREPARING THE
INSTALLATION LOCATION
Symphony Acoustic Enclosures
Although Sonance Cinema Select speakers
are designed to be relatively insensitive to
variations in enclosure volume, you can
achieve the ultimate performance by
installing a Symphony Acoustic Enclosure
(part# 91688) for each speaker. This fullybraced enclosure is made from ½” MDF,
and will deliver free-standing speaker performance from Cinema Select in-wall
speakers.
Note: This enclosure is not retrofittable and must be installed in new
construction only.
Sonafill®Resonance Cancellation System
To reduce sound transmission to adjacent rooms and improve speaker
performance when a Symphony wood acoustic enclosure cannot be
used (such as in a retrofit installation), Sonance recommends installing
the Sonafill
®
in-wall resonance cancellation system (part# 91698) in each
speaker’s wall cavity. Sonafill utilizes acoustic damping tiles and acoustic
absorption pillows to cancel drywall vibration and reduce the resulting
coloration of the speakers’ sound. The Sonafill system can be easily
retrofitted into existing walls.
INSTALLING THE SPEAKERS
New Construction
For new construction installations without Acoustic Enclosures,
Sonance recommends using a Symphony FlexBracket (part#92901) to
reserve a location for the speaker. The FlexBracket is nailed or screwed
to the studs and serves as a guide for the drywaller so that the speaker
hole will be in the desired location once the drywall is installed.
Symphony FlexBrackets are compatible with the RotoLock mounting
system (see Retrofit, below).
Illustration 6 shows a FlexBracket installation example:
Retrofit
Sonance Cinema Select Speakers feature an integral RotoLock™
mounting system for quick mounting directly into existing walls. Once
the hole is cut and the cable is run, you can install the speaker in a
matter of seconds.
1. Determine the location for the speaker (see Speaker Placement).
2. Perform an obstruction survey to be certain that there are no studs,
conduit, pipes, heating ducts or air returns that will interfere with the
speaker.
3. The cutout for the Cinema Select LCR and SUR speakers is 7
1
/16”
(179mm) x 11¼” (286mm). There also must be at least 3
7
/
8” (99mm)
depth within the wall cavity for the speaker.
4. Find the cutout template provided in the speaker packaging. 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 outline and insert a coat hanger wire into the hole to
feel-around for possible obstructions.
5. Cut the speaker hole using a drywall saw, and run the speaker wires.
6. Remove the paint plug from the speaker. Connect the speaker wire to
the terminals on the back of the speaker. Make sure to connect the
amplifier ‘+’ to the speaker ‘+’ and the amplifier ‘–’ to the speaker ‘–’.
