Before you begin

Your 301

Series IV Direct/Reflecting

speakers re-create a natural balance of reflected and

direct sound energy for an open, spacious performance. They are designed at Bose

bring you high-quality listening pleasure.

The Direct/Reflecting

tweeter inside each speaker creates a pattern of sound similar to

what you experience at a live concert. In addition, the Stereo Targeting

tweeters help

establish the natural balance of sound, for full enjoyment of stereo even when you move

around the room. These distinct left and right speakers also feature tuned port enclosures

that contribute to their deep, room-filling bass. An advanced crossover design adds to the

realism and clear definition of both musical instruments and voices.

Your 301 Series IV speakers are significantly different from conventional speakers, so be

sure to read this owner’s guide. It will help you set up and use your speakers properly, for

the greatest enjoyment.

Unpack the carton

Carefully unpack the carton and save all packing materials for possible future use. Check

the carton contents (Figure 1).

If either speaker appears damaged, do not use them. Instead, repack both speakers in the

original carton and notify your authorized Bose dealer immediately.

Note:

Now is a good time to record the speaker serial numbers on page 2 of this guide

and on your warranty card.

Select the locations for your 301

speakers

Bose

301 speakers are designed to fit horizontally on a table or shelf (Figure 2). Be sure to

choose a stable 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 4 m) apart.

• Choose a stable 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 cm) from the speakers to the floor or ceiling.

• Leave at least 24 inches (60 cm) from the speakers to any TV screens or monitors.

• Keep the back of the speakers within 18 inches (45 cm) of the wall behind them.

• Do not place the speakers exactly halfway between the floor and ceiling or any other

sound-reflecting hard surface.

• Do not put the speakers in a vertical position.

Note:

Bose speaker stands or wall brackets can extend your placement options. See

“Optional accessories” on page 10.

Setting Up

CAUTION:

301 speakers are designed

specifically for placement on a

stationary shelf, table, or stand.

On smooth surfaces like

marble, glass or highly pol-

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

speaker for added stability and

protection. The feet go in the

corners of the flat surface,

inside the seam.

Do not use these speakers in

a moving vehicle.

To mount the speakers on a

wall, use only the Bose WB-3

wall mounting bracket. Please

follow the mounting instructions

that come with these brackets.

Improperly mounted speakers

may fall, causing injury and

damage.

To contact Bose, please refer

to the subsidiary offices

listed on the inside back

cover of this owner’s guide.

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.

Setting Up

CAUTION:

Never use broken or frayed

wiring, which can result in

electrical shock or damage.

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 a receiver (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 a wall or under a floor, check your local

building code requirements and safety regulations. You may want to contact an 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

⁄

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 proper terminal (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).

1. Connect 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.

3. Connect the second cord to the left speaker and LEFT SPEAKER OUTPUT. Follow the

steps in 1 and 2 above.

How to make terminal connec-

tions

CAUTION:

Before making any connec-

tions, turn off your receiver

and unplug it from the AC

power (mains) outlet. Not

doing so may result in dam-

age to your system.

Setting Up

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.

Bridged wires can short circuit and damage the amplifier. Tighten any loose connections

before you plug in the receiver and turn it on.

Test the speakers

To make sure your speakers operate correctly:

1. Place the speakers less than 6 inches (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.

3. Make sure that all special effects (such as surround sound) are turned off.

4. Set the balance control to normal (center position).

5. Play some deep bass passages of music through the speaker.

The sound should seem to come from a point 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 1 through 5 above to re-test

the speakers.
