SONANCE C201SQ
IN-CEILING SPEAKERS
DISTRIBUTED AUDIO PLACEMENT
The Sonance C201SQ speaker posses extremely smooth and
predictable off-axis frequency response. The chart below shows how
far apart the speakers can be placed in a distributed audio system. The
calculations are based on +/- 45 degrees of coverage from the
speaker, and listener ear heights of 62" for standing and 40" for
seated.

2 - CHANNEL AUDIO PLACEMENT
In a standard two channel audio system, the C201SQ speakers should
be separated approximately 6 to 10 feet apart. If possible, the left and
right speakers should be located the same distance from the listening
position.
HOME THEATER PLACEMENT
When using the C201SQ speakers as a rear channel speaker, the
speakers should be located from 2 to 6 feet behind the main listening
position. The speakers should be separated approximately 6 to 10 feet
apart.

WIRE GAUGE AND QUALITY
The total wire resistance should be less than 10% of the speaker
impedance. If using an 8 ohm speaker, your total wire resistance
should be no more than 0.8 ohms.
In simple terms, the extra resistance from the wire will have a very
negative effect on the sound quality of the speaker. The sound can be
less dynamic, definition of bass frequencies can be reduced, and in
extreme cases, the high frequencies can be attenuated. Amplifier
power is also wasted in the wire, reducing the maximum output level
of the system.
Please refer to the following chart when deciding on the appropriate
wire gauge for your installation.

necessary in new construction installations when reserving a location

mounting system
All Sonance speakers are designed to be relatively insensitive to
changes in enclosure volume. To achieve the ultimate performance
from the C201SQ speaker, a section of the ceiling bay can be
sectioned off to form a back box. Building this enclosure will create a
dramatic improvement in the quality of bass response and power
handling.
Back box volume requirements:
Insulating the ceiling cavity
Speaker performance can be enhanced by insulating the cavity with
fiberglass insulation.
When installing speakers in a ceiling, it is best to lay a sheet of
unfaced fiberglass insulation over the back of the speaker.
To further improve the sound quality, install insulation in the bays
adjacent to the speaker location. This will reduce noise produced by
the unsupported drywall.
Sonafill
Sonafill is a retrofitable acoustical treatment for loudspeakers that
virtually eliminates the noise produced by resonating drywall and
dramatically improves mid-bass sound quality. Sonafill also reduces
room-to-room noise especially in multi-channel installations where
many speakers are installed.
The Sonafill system consists of two pillows and four tiles. Installation is
accomplished by first adhering the tiles to the inside of the cavity, then
stuffing the two pillows in place behind the tiles.

The FlexBracket will serve as a guide for the drywaller when cutting
holes for in-ceiling speakers. The FlexBracket is nailed or screwed to
the joists 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 ceilings. 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 joist, conduit, pipe, heating
duct or air return will interfere with the speaker.
The C201SQ speaker requires a 7-5/16" x 7-5/16" cutout. There must
also be 3-3/4" of depth within the ceiling for the speaker.
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 ceiling. If you are unsure about obstructions, drill a
small hole in the center of the circle 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.
