SAFETY WARNING
This woofer has FastMount® tabs that prevent the woofer from falling out of
the mounting hole during the installation process.
The edges of FastMount tabs are very sharp. Use caution
when handling the woofer.
See Installing The Woofer (page 3) for complete information about the
FastMount tabs.
IMPORTANT SAFETY INSTRUCTIONS
Basic safety precautions should always be followed When using your Virtuoso
A800D woofer, to reduce risk of fire, electric shock, and injury to persons:
1. Read and understand all instructions.
2. Retain these instructions for future reference.
3. Follow all warnings and instructions in this manual and marked on the
product.
4. Any service or repair required must be performed by qualified factoryauthorized personnel.
5. Do not use the amplifier in a high-humidity environment or near water —
for example in a wet basement, or near a wet bar or swimming pool.
6. Never touch the speaker driver or push any object through the grille.
7. Always provide adequate ventilation for the amplifier.Allow a minimum of
one (1) inch above and three (3) inches behind the amplifier. Do not block
the cooling vents on the amplifier case.
8. The amplifier should be situated away from heat sources such as heat
registers, radiators, stoves, or other appliances that produce heat.
9. The amplifier should only be connected to a power supply of the type
marked on its back panel. The power supply cord should be routed to avoid
damage from contact with sharp objects or being stepped on.
10. Unplug the amplifier during thunderstorms or when the woofer will be
unused for extended periods of time.
11. Exercise care to avoid spilling liquids on or in the amplifier or woofer.
12. Do not place the amplifier on an unstable
table, stand, or cart. Improper placement of
the amplifier may cause it to fall on an adult
of child causing serious injury, as well as
damage to the amplifier.
13. Do not expose the amplifier to dripping or
splashing. Do not place objects filled with
liquids, such as vases, on the amplifier.
14. Cleaning: The amplifier and woofer should
be cleaned only as recommend by the manufacturer.
15. Non-Use Periods: Unplug the amplifier’s power cord from the electrical
outlet when the woofer will be unused for a long period of time.
16. Damage Requiring Service: The woofer and/or amplifier should be
serviced by qualified service personnel when:
A. The power cord or plug has been damaged
B. Objects have fallen, or liquids have been spilled into the amplifier
C. The amplifier or woofer have been exposed to rain.
D. The amplifier and/or woofer does not appear to be operating properly
or exhibits a marked change in performance.
E. The woofer or amplifier has been dropped or appears to have been
damaged.
17. Servicing: The user should not attempt to service the woofer or amplifier
beyond that described in these instructions. All other servicing should be
referred to qualified service personnel.

FlexBracket (part# 92246): Plastic template to reserve a mounting
hole for the woofer in new construction. Designed to be used with the
RotoLock® mounting system.
VirtuosoDCoverplate (part# 92244): Covers the hole made by the FlexBracket

Acoustic Enclosure (part# 91708): ½” MDF enclosure that
provides ideal acoustic performance and maximum reduction of sound
transmission into adjacent spaces. Designed for use only in new construction.
Sonafill®In-Wall System (part# 91698): Retrofittable acoustical
treatment for in-wall speakers consisting of two pillows and four tiles that
virtually eliminates noise produced by resonating drywall. Dramatically
improves midbass sound quality and reduces sound transmission into
adjacent rooms.
WOOFER PLACEMENT
The Sonance Virtuoso A800D woofer fits into walls built with standard
2” x 4”stud construction.
Home Theater Placement
For highest output and best overall performance the Virtuoso A800D woofer
should be placed in the front corner of the room. Place the woofer as close as
possible to the left, center and right speakers to assure seamless integration of
the sound from the main speakers and the woofer.
• The woofer should not be mounted in the same stud bay as the left or
right speakers.
Use Illustration 1 as a guide.
For optimum results contact your Authorized Sonance Dealer for advice.
2-Channel Placement
In a 2-channel system the A800D should be located on a corner of the room,
as close as possible to the left or right speaker. Corner placement provides the
highest output and best overall performance for the A800D woofer.
Use Illustration 2 as a guide.
For optimum results contact your Authorized Sonance Dealer for advice.
WIRE GAUGE
Extra resistance in the speaker wire can make speakers 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 woofer,
a section of the stud bay can be sectioned-off to form a back box. Building
such an enclosure will create a dramatic improvement in your woofer’s bass
performance and power handling.
Ideal back box volume requirements: 1.5 cu. ft. (45.5 liters)
Insulating the Wall Cavity
You can reduce sound transmission to adjacent rooms and further improve
speaker performance by inserting a sheet of unfaced fiberglass insulation over
the back of the woofer.
To reduce noise produced by unsupported drywall, install fiberglass
insulation in the stud bays adjacent to the woofer location.
