PARTS LIST
Each Virtuoso A800DR includes the following items:
(1) Sonance Virtuoso A800DR speaker
(1) Sonance Virtuoso A800 150 watt amplifier
(1) Paintable grille
(1) Plastic paint plug to protect speaker during painting

HOME THEATER PLACEMENT
For best performance the Virtuoso A800DR woofer should be placed in
the front corner of the room as shown in the illustration below. Keep
the woofer as close as possible to the left, center and right speakers
to assure seamless integration of the sound from the main speaker
and the woofer.
The woofer should not be mounted in the same joist bay as the left
and right speakers.

2 - CHANNEL AUDIO PLACEMENT
In a two channel system the woofer should be located in a corner of
the room and as close as possible to the left or right speaker. Corner
placement of the woofer will provide more predictable performance
and higher output level.

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 affect on the sound quality of the speaker. The sound can be
less dynamic, definition of bass frequencies can be reduced. 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.

OPTIONAL ACCESSORIES
FlexBracket - part number 90-1358
Coverplate - part number 91457
Plastic template to reserve hole in new construction.
Designed to be used with the Roto-lock3 mounting system.
Designed to cover hole made by FlexBracket3 until the
speaker is installed.
Sonafill3
Sonafill is a retrofitable acoustical treatment for loudspeakers that
virtually eliminates the noise produced by resonating drywall and
dramatically improves bass sound quality. Sonafill also reduces roomÂto-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.

New Construction
The Virtuoso A800DR speaker features an integral Roto-Lock3
mounting system for quick mounting into ceilings. The Virtuoso DR
FlexBracket is only necessary in new construction installations when
reserving a location for the speaker is desired.
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.

PREPARING THE INSTALLATION LOCATION
All Sonance speakers are designed to be relatively insensitive to
changes in enclosure volume. To achieve the ultimate performance
from the Virtuoso A800DR 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 requirement:
A800DR 1.50 cubic feet (45.5 liters)
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.

Retrofit
With the Roto-Lock 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 Virtuoso A800DR speaker requires a hole that is 10" in diameter.
There must also be 5-3/4" 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.
