Bose> 301 speakers are designed to fit horizontally on a table or shelf (Figure 2) Be sure to
choose astable and level surface for each speaker
Place
the left and right speakers (marked on the back of each one) on the left and right
sides of your room, as you face them Exactly where you put them depends on the size and
style of your room and where you think they sound best Feel free to experiment to find a
location
that is both convenient and provides the sound you prefer
Note: Because the grilles on the front of each speaker protect the drivers inside, we
recommend that you do not remove the grilles
Here are some basic guidelines
•Place
the speakers 4 to 12 feet (1 to 4m) apart
• Choose astable and level surface for each speaker, and attach the rubber feet
•Leave
at least 12 inches (30 cm) of space from the end of a speaker to the side wall
•Leave
at least 18 inches (45 em) from the speakers to the floor or ceiling
•Leave
at least 24 inches (60 cm) from the speakers to any Nscreens or monitors

specifically for placement on a
stationary shelf, table, or stand
On smooth surfaces like
marble, glass
or highlypol-
ished wood, vibrations
may
cause the speakers to slide
So
be sure to attach the self-
adhesive rubber feet
to the
bottom surface
of each

Figure 2
Placement guidelines
CAUTION:
For the most realistic sound
image, make sure the left
speaker
is placed on the left
and the right speaker is on
the right side
of your room, as
you face them

Choose the cord
It is important to use the proper gauge (thickness) of speaker cord Standard zip cord
(2-conductor, 18-gauge
Wire) works for most applications You can find this wire at most
electrical and hardware stores
You will need thicker wire if your speakers will be more than 30 feet (9 m) from areceiver (or
amplifier) Refer
to the wire recommendations under "Technical information" on page 10, or
contact your authorized Bose$ dealer for more information
Note: Before running speaker cord through awall or under afloor check your local
building code requirements
and safety regulations You may want to contactan electrical
installer for this information
Prepare the cord
Speaker cord consists of two insulated wires The insulation around one wire is marked
(striped, collared,
or ribbed). This marked wire is always positive (+) The plain wire is always
negative (-) These wires correspond
to the red (+) and black (-) terminals on the speakers
and the receiver
At the ends
of each cord, strip approximately 1;2 inch (12 mm) of insulation from both wires
Twist the bare end
of each wire so loose strands will not touch across terminals Be sure to
connect each wire to the properterminal (positive to positive and negative to negative)
Note: It is sometimes difficult to distinguish wire markings Inspect both wires carefully
Make the connections
Just press the terminal tab on the back of each speaker to insert the appropriate wire
(Figure
3)
1Connect one speaker cord to your right speaker
a. Attach the marked wire at one end to the red (+) terminal.
b. Attach the plain wire at that end to the black (-) terminal.
2. Connect the other end of the same cord to the RIGHT SPEAKER OUTPUT of your
receiver
a. Attach the marked wire to the red (+) terminal.
b. Attach the plain wire
to the black (-) terminal.
3Connect the second cord
to the left speaker and LEFT SPEAKER OUTPUT Follow the
steps in 1and 2above.
Red terminal tabl--~~~~~
CAUTION:
Never use broken or frayed
wiring, which can result
in
electrical shock or damage
CAUTION:
Before making any connec-
tions turn offyour receiver
and unplug it from the AC
power (mains) outlet Not
doing so may result
in dam-
age to your system
Figure 3
How to make terminal connec-
tions

Check the connections
Check to be sure all connections are made positive to positive (+ to +) and negative to
negative (- to -) (Figure 4) Make sure that no loose strands of wire touch across terminals

Test the speakers
To make sure your speakers operate correctly
1Place the speakers less than 6inches
(15 cm) apart, facing each other
2
Turn on your receiver Set the receiver to MONO (monophonic), if that is an option on
your receiver
3Make sure that all special effects (such as surround sound) are turned off
4Set the balance control
to normal (center position)
5Play some deep bass passages
of music through the speaker
The sound should seem
to come from apoint between the two speakers The bass should
be full and natural If it is not, one
of the connections may be reversed, causing the speakers
to play out of phase (refer to "Make the connections" on page 6)
To correct the problem, make sure all the wires are connected positive to positive (+ to +)
and negative to negative (- to -) Then repeat steps 1through 5above to re-test
the speakers
