Selecting speaker cable
If your cables are not yet installed, use these guidelines
for choosing and using speaker cable. If your cables are
already installed, check
to be sure they meet these
standards.
Gauge Maximum Length
18 AWG (0.82 mm
2)20 ft

(9 m)
14 AWG (2.1 mm
2)50
ft (15 m)
12 AWG (3.3 mm
2)90
ft (27 m)
Consider the location of the speakers and be sure to
allow enough cable to reach each one. This includes the
extra length needed for wiring the speaker before
inserting it into the ceiling.
PREPARATION
Preparing the cable wires
Speaker cable consists of two insulated wires. The
insulation around one wire is marked (striped, collared,
or ribbed) to identify it as positive. The other wire is
negative.
Note: It is sometimes difficult to distinguish wire
markings. Inspect both wires carefully.
1. Strip approximately '/2 in. (13 mm) of insulation from
both wires.
2. Twist the bare end of each wire so loose strands will
not touch across terminals.
Be sure
to connect each wire to the proper speaker
terminal, positive
to positive (+) and negative to
negative (-).
Note: For information on installing cable, consult a
professional electrician oraudio/video installer, or look
for reference books at alocal home building retail store.

Cutting the speaker hole
Be sure to cut carefully to make the hole as regular as
possible. However, when the speaker is
in place, the
frame overlaps the cutting edge by %in. (0.6 cm), which
masks minor cutting inaccuracies.
1. Hold the cutting blade in avertical position and keep
it straight as you
cut the hole.
This helps prevent the blade from angling away from
the outlined circle.
2. Insert the tip of your saw into the pilot hole and cut
most of the way around the circular outline.
3. Place one hand under the circle to brace it and
complete cutting the hole.
WARNING: Keep fingers away from the Gutting blade.
4. Remove the cutout section.
5. Clear away any torn or rough material from around
the hole.
Such material can interfere with atight seal between
the speaker and the ceiling.
INSTALLATION
Getting the wire ready
When your speaker cable is within reach of the hole you
have cut, follow
the procedure below:
1. Push any insulation away from inside the speaker
hole.
Be sure that all blown insulation
is at least 4to 6 in.
(10 to 15 cm) from the edges of the hole.
2. Locate and pullout at least 14 in. (36 cm) of your
speaker cable.
Allow enough cable
for where you stand to connect
the wires.

Painting the exterior parts
You can paint the grille and frame of your Virtually
Invisible® 791 speakers before you install them.
Be sure
to use paint that is appropriate to the technique
you choose, as described below. Painting
is optional
and Bose cannot be responsible for the quality
of
adhesion or finish of non-factory-applied paints.
WARNING: Follow all recommended safety procedures
for the chemicals involved.
This includes the properuse
of eye protection, ventilation systems, respirators or filter
masks,
and fire safety equipment ifflammable solvents
are used.
Painting the grille
It is important to prevent paint from clogging the grille
perforations. This can adversely affect performance.
You can use a dry brush or spray paint technique, as
described here. However,
do not use apaint roller.
•
BE SURE to rotate the Bose® logo to the position you
want before painting begins.
•Clean the grille
to remove possible contaminants.
Even fingerprints can prevent uniform coverage.
•Check
to be sure the paint is distributed evenly and
covers the grille thoroughly.
•Use atissue paper
or clean cloth to protect the
painted grille when you remove the paint shield
or
attach the grille to the speaker.
REFERENCE
Using a dry brush technique
Unthinned latex paint is appropriate for this method.
Be sure
to put down enough paper to cover your work
area and allow for repeatedly blotting the brush.
1. Dip the tip of aclean, dry brush in the paint.
2. Stroke across apiece of paper to reduce the amount
of paint on the brush. When you can see individual
bristle marks, the brush is ready
to use on the grille.
3. Stroke lightly back and forth on the front of the grille,
in ahorizontal direction, until you need more paint.
Tip: If paint clogs any of the grille perforations, try
angling
your stroke or blow gently to unclog the paint.
4. When the entire grille is covered, turn the grille 1800
and repaint it using back-and-forth strokes.

Using aspray technique
Latex or oil-based architectural paint requires thinning
for use with asiphon-feed spray gun. Set the spray
gun at 30 psi
(2.1 bar) for application in a 3- to 5-in.
(7.6-12.7 cm) fan pattern.
The thinning formula depends on
the type of paint you
are using.
•For use
of vinyl acrylic latex paint, thin as follows:
To 6parts of paint, add 3parts of water and mix
thoroughly. Add 1part
of denatured ethyl alcohol
(which breaks
down paint particles so they do not
clog the grille) and mix again.
•For use
of architectural or automotive paints:
This type
of paint should be used by aprofessional
with the right equipment and technique. This paint
also must be thinned, using asolvent.
•For use
of lacquer or enamel spray paint in acan:
No further thinning
is needed.
Then:
1. Suspend the grille or place it on awire screen to
prevent dirt or dried paint particles from blowing
back into
the perforations.
2. Apply the paint to the grille surface at a45° angle.
Then rotate the grille by 180° and repaint
it at 45°.
3. Make sure the paint is dry before you attach the
grille
to the speaker.
The paint may feel
dry to the touch in afew minutes.
However, if alcohol has been added, it may take
several days to fully cure.
'---
Tip: To dislodge a paint clog, blow gently on the
cloggedarea.
If that does not work, immediately wash
the grille with the appropriate solvent. Make sure the
grille
is thoroughly dry before repainting.
Piercing aperforation with asharp implement to remove
apaint clog can cosmetically damage the grille and is
not recommended.

Painting the frame
Before you begin, protect working parts of the speaker
by inserting
the template/paint shield that came in the
carton.
Press
the edges of the shield against the inside rim of
the speaker until the tabs catch to hold the shield in
place.
This protects working parts
of the speaker and helps
keep your paint edge even.
You can use the same conventional spray or roller
equipment used
to paint your wall or ceiling and either
latex
or oil-based paints, which adhere to the speaker
frame. However, both
types of paint can be easily
scratched through careless handling.
CAUTION: Be careful so the paint does not puddle or
run. You may want to use abrush for spreading paint
where needed.

OUR COMMITMENT TO YOU
We take great pride in designing each of our products with the goal of providing the high-
est accuracy musical performance possible in the price range
of that product. We strive to
reproduce the musical sounds as closely
as possible to those of the original performance.
And we strive to avoid flashy sounds such as those associated with accentuated bass
and/or treble frequencies. While those sounds may be initially attractive to the novice,
they are not real and are not enduring.
In addition, we use only the highest quality parts
and the latest assembly and quality control techniques to ensure the reliability and long
life
of our products.
Our reputation rests on our steadfast pursuit
of this policy in sound systems for the home,
the automobile, and businesses.
At
Bose® we reinvest 100% of our earnings back into the company. This enables us to
support research that continually gives rise to new technologies for improving sound
reproduction.
When you purchase any product from Bose, we encourage you
to compare it, as we do, to
competitive products for musical accuracy. We believe that this process will enhance your
appreciation
of the product you select.
With best wishes from all
of us at Bose for many years of enjoyable listening.

We take great pride in designing each of our products with the goal of providing the high-
est accuracy musical performance possible in the price range
of that product. We strive to
reproduce the musical sounds as closely
as possible to those of the original performance.
And we strive to avoid flashy sounds such as those associated with accentuated bass
and/or treble frequencies. While those sounds may be initially attractive to the novice,
they are not real and are not enduring.
In addition, we use only the highest quality parts
and the latest assembly and quality control techniques to ensure the reliability and long
life
of our products.
Our reputation rests on our steadfast pursuit
of this policy in sound systems for the home,
the automobile, and businesses.
At
Bose® we reinvest 100% of our earnings back into the company. This enables us to
support research that continually gives rise to new technologies for improving sound
reproduction.
When you purchase any product from Bose, we encourage you
to compare it, as we do, to
competitive products for musical accuracy. We believe that this process will enhance your
appreciation
of the product you select.
With best wishes from all
of us at Bose for many years of enjoyable listening.
