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.

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
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
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.
