INTRODUCTION
Thank you for purchasing Sonance Symphony® in-ceiling speakers. When
properly installed, these speakers will give you many years of entertainment
pleasure. To get the most out of your new speakers, please read this
manual thoroughly before you begin installation.
Since all of the Sonance Symphony in-ceiling speakers have the same
exact footprint and have identical installation requirements, the
directions in this manual apply to each model. This manual covers the
following speaker models:
To achieve the best performance, Sonance recommends that these
speakers be installed by a Sonance Authorized Dealer/Installer.
PARTS LIST
Your Sonance Symphony in-ceiling speakers include the following:
• (2) Sonance Symphony Speakers
• (2) Paintable Grilles

Dramatically improves midbass sound quality and reduces sound
transmission into adjacent rooms.
Symphony Acoustic Enclosure (part# 91688) — ½” MDF enclosure that
provides ideal acoustic performance and maximum reduction of
sound transmission into adjacent spaces. Designed for use only in new
construction.
Fire-Rated Back Can (part# 91906) — Meets ASTM E 119, CAN/ULC S 101,
NFPA 251, UBC 7-1 and UL 263 criteria for commercial installations.
SPEAKER PLACEMENT
The locations of the speakers should be determined by considering your
primary listening location, the primary use for the speakers (distributed
audio, 2-channel or home theater) and aesthetic values. For optimum
results contact your Authorized Sonance Dealer for advice.
Distributed Audio Placement (Mono Signal)
Sonance Symphony in-ceiling speakers have very smooth and
predictable off-axis response, increasing placement options while
providing excellent coverage in distributed audio systems. The chart at
the top of the next column shows how far apart the speakers can be
placed while still providing good coverage. The distances are based on
ear heights of 62” for standing listeners and 40” for seated listeners.
Home Theater Placement
Left, Center and Right Speakers
• Place the left, center and right speakers from 1 foot to 2 feet in front of
the video screen, anywhere from 6 feet to 10 feet apart, with the center
channel speaker as close to midway between the left and right speakers as
possible.
• Place the left & right speakers at least 2 to 3 feet away from the side walls.
• The main listening position should be between 4 and 10 feet away from
the speakers.
Left & Right Surround Speakers (5.1-Channel System)
Locate the left and right surround speakers on the ceiling between 2 feet
and 6 feet behind the listening position. The speakers should be between
6 feet and 10 feet apart. Since the surround speakers are usually calledupon to create diffuse effects like the sound of wind or rain, they can be
located close to walls without adversely affecting sound quality.
Use Illustration 1 as a guide.
Left & Right Surround and Surround Back Speakers
(7.1-Channel System)
• Left & Right Surround Speakers: In a 7.1-channel system, place the
left and right surround speakers directly to the sides of the listening
position, between 6 feet and 10 feet apart. The speakers can be placed
close to the side walls.
• Surround Back Speakers: Place the surround back speakers between
2 feet and 6 feet behind the listening position. The surround back
speakers should be closer together than the left and right surround

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 an 8-ohm
speaker, 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
All Sonance speakers are designed to be relatively insensitive to
variations in enclosure volume. To achieve the ultimate performance
from your speakers, a section of the ceiling bay can be sectioned-off to
form a back box. Building such an enclosure will create a dramatic
improvement in bass performance and power handling.

Insulating the Ceiling Cavity
To reduce sound transmission to adjacent rooms and further improve
speaker performance, insulate the ceiling cavity by inserting a sheet of
unfaced fiberglass insulation above and below the speaker.
To reduce noise produced by unsupported drywall, install fiberglass
insulation in the ceiling bays adjacent to the speaker location.
Symphony Retrofit Enclosures
For installations where it isn’t possible to section-off the ceiling bay to
form a back box (such as when you’re retrofitting the speakers into an
existing ceiling), you can effectively reduce sound transmission into
adjacent rooms by fitting the speakers with optional Symphony Retrofit
Enclosures (part# 92098). This enclosure is designed specifically to be
used with Symphony speakers, and will noticeably reduce sound
“spillover”from the rear of the speakers into adjacent rooms and spaces.
INSTALLING THE SPEAKERS
New Construction
For installations in new construction, Sonance recommends using
a Symphony FlexBracket (part#92902) 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).
Retrofit
Symphony Speakers feature an integral RotoLock® mounting system for
quick mounting directly into existing ceilings and 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 all Symphony In-Ceiling Speakers is 8
5
/32” (207mm).
There also must be at least 5
3
/16” (132mm) depth within the ceiling
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 ceiling.
• 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 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. Double-check that you connected amplifier + to speaker + and amplifier – to speaker –.
