DESIGN

FEATURES

The

BOSE

Model

301

Direct/Reflecting

loudspeaker

incorporates

several

features

that

make

its

operation

and

placement

different

from

other

loudspeakers.

The

exceptional

performance

of

the

Model

301,

to

a

great

degree,

can

be

attributed

to

Asymmetrical

Design,

the

Direct

Energy

Control,

and

a

Dual

Frequency

Crossover

Network.

ASYMMETRICAL

DESIGN

The

Asymmetrical

Design

of

the

Model

301

provides

a

high

proportion

of

reflected

sound

at

high

frequencies

and

contributes

to

the

exceptionally

spacious

stereo-

phonic

reproduction.

To

provide

balanced

spatial

properties

in

stereo

reproduction,

the

Model

301

stereo

pair

is

designed

so

that

the

speaker

used

on

the

left-hand

side

of

the

room

(this

speaker

is

called

“Part

1”)

is

a

mirror

image

of

the

speaker

on

the

right-hand

side

(this

speaker

is

called

“Part

2”).

The

Asymmetrical

Design

and

mirror

image

construction

of

the

Model

301

are

shown

in

Diagram

1

(page

5).

The

tweeters

direct

most

of

their

energy

toward

the

side

walls

of

the

room.

The

side

walls

reflect

high

frequency

energy

uniformly

throughout

the

listening

area,

resulting

in

a

stereo

image

extending

from

one

wall

of

the

room

to

the

other

(Diagram

2,

page6).

The

advantage

of

this

design

is

that

minimum

reliance

is

placed

on

the

rear

wall

of

the

room

for

providing

reflections.

This

maximizes

the

flexibility

of

placement

of

the

loudspeaker.

DIRECT

ENERGY

CONTROL

This

control,

located

at

the

top

of

the

cabinet,

allows

you

to

select

the

proportion

of

direct

to

re-

flected

sound

at

high

frequencies

to

produce

the

optimum

spatial

characteristics

for

your

particular

room.

If,

for

example,

the

side

walls

of

the

room

are

absent,

too

far

away,

or

covered

by

absorbing

material,

'

the

control

can

be

set

to

provide

predominantly

direct

sound

at

high

frequencies.

A

predominance

of

direct

sound

results

in

a

stereo

localization

of

sounds

primarily

to

the

area

between

the

two

speakers.

Sometimes

this

more

“inti-

mate”

sound

is

preferred

for

soloists

and

small

groups.

If

a

reflecting

side

wall

is

present,

and

a

more

spacious

sound

presentation

is

desired

(such

as

for

an

orchestra),

the

control

can

be

set

to

provide

a

larger

proportion

of

reflected

sound

at

high

frequencies.

This

results

in

sound

that

actually

extends

beyond

the

spacing

of

the

speakers.

DUAL

FREQUENCY

CROSSOVER

NETWORK

Contrary

to

tradi-

tional

design

philosophies,

the

crossover

network

of

the

Model

301

deliberately

overlaps

the

response

of

the

woofer

and

tweeter

by

over

an

octave,

and

adjusts

the

amplitude

and

phase

response

of

the

woofer

and

tweeter

to

provide

exactly

complementary

*Any

surface

that

feels

hard,

such

as

wood,

glass,

wallboard,

plaster

or

brick,

is

a

good

reflector.

A

soft

surface,

such

as

acoustic

tile,

drapery,

or

upholstered

furniture,

will

absorb

sound.

characteristics.

This

Dual

Frequencv

Crossover

permits

both

driv-

ers

to

operate

throughout

the

crucial

range.

Dis-

tributing

the

energv

between

the

two

drivers

eliminates

the

undesirable

''point

source'

effect

of

a

conventional

loudspeaker.

This

results

in

more

sound

and

unusual

claritv

and

naturalness

through

the

middle

and

frequencies.

4.

INSTALLATION

The

Model

301

provides

a

versatilitv

of

placement

and

adjustment

that

will

produce

excellent

performance

in

virtually

any

room.

However,

all

loudspeakers

will

sound

better

if

installed

properly.

The

following

guide-

lines

should

be

followed

in

installing

the

Model

301.

A.

Speaker

Placement

For

optimum

performance,

the

Model

301

should

be

positioned

hori-

zontally

on

a

bookshelf,

table,

or

pedestal.

However,

excellent

per-

formance

can

also

be

obtained

with

vertical

placement.

HORIZONTAL

PLACEMENT

The

speaker

labeled

“Part

1”

is

nor-

mally

used

on

the

left

side

of

the

room

and

“Part

2”

is

normally

used

on

the

right

side

(Diagram

2).

The

speakers

are

best

located

1%

to

5

feet

above

the

floor,

with

each

speaker

1%

to

3

feet

from

a

reflecting

side

wall,

and

with

as

much

free

space

around

the

tweeter

side

of

the

speaker

as

possible.

The

following

guidelines

should

be

followed:

1.

Both

speakers

should

be

at

least

18

inches

above

the

floor.

2.

If

the

speakers

are

hung

from

the

ceiling

or

placed

on

a

high

bookshelf,

the

space

from

the

ceiling

to

the

top

of

the

speaker

should

be

at

least

18

inches.

Placing

the

speaker

exactly

halfway

between

floor

and

ceiling

is

not

desirable

for

best

bass

response.

3.

The

ideal

separation

between

speakers

should

be

from

6

to

12

feet,

with

a

minimum

spacing

of

4

feet.

If

spacing

greater

than

12

feet

is

used,

the

alternate

placement

shown

in

Diagram

3

should

be

tried.

This

will

provide

a

stronger

sound

image

in

the

space

between

the

two

speakers.

4.

If

possible,

locate

the

speaker

1%

to

3

feet

from

the

side

wall

or

openings

into

adjacent

rooms

(Diagram

2,

page

6).

5.

Allow

at

least

1%

feet

of

space

on

the

side

of

the

speaker

where

the

Direct

Energy

Control

and

tweeter

are

located.

This

will

provide

for

the

best

dispersion

of

high

frequencies

into

the

room.

6.

The

most

accurate

bass

will

be

obtained

with

the

back

of

the

speaker

against

a

wall

or

moved

out

up

to

2

feet.

Further

spacing

from

the

wall

will

result

in

some

reduction

in

middle

bass

response.

This

effect

happens

with

а//

loudspeakers.

VERTICAL

PLACEMENT

Should

you

desire

to

position

the

speak-

ers

vertically,

the

above

guidelines

should

be

followed,

with

the

exception

that

No.

5

will

apply

to

the

areas

above

each

speaker

rather

than

to

areas

on

the

side.

Be

sure

to

place

the

speakers

so

that

the

tweeter

is

on

top.

As

with

all

small

speakers,

placement

directly

on

the

floor

will

accentuate

bass

and

restrict

distribution

of

high

frequencies.

Note

that

for

vertical

placement,

the

nameplate

can

be

rotated

and

moved.

Carefully

remove

the

foam

piece

containing

the

name-

plate.

Squeeze

the

small

tab

retaining

the

nameplate.

Reposition

the

nameplate

and

replace

the

tab.

QUADRIPHONIC

OPERATION

АІ

of

the

above

considerations

are

valid

when

operating

the

BOSE

Model

301

speaker

system

in

quadriphonic

or

four-channel

sound

reproduction.

Because

of

the

flexibility

the

BOSE

Model

301

speaker

system

provides

in

room

placement,

the

operation

of

the

speaker

system

in

four-channel

modes

is

optimum

for

more

listening

environments

than

that

of

conventional

loudspeakers.

This

is

due

to

the

fact

that

the

amount

of

direct

energy

reaching

the

listening

area

can

be

specifically

adjusted

at

each

speaker.

Diagram

4

indicates

the

placement

position

of

the

BOSE

Model

301

in

quadriphonic

and

stereo

operation.

If

your

listening

environment

does

not

allow

the

possibility

of

placing

speakers

behind

you,

the

Model

301

speakers

can

be

placed

as

shown

along

the

side

walls

of

the

listening

area

with

the

Direct

Energy

Control

set

for

mini-

mum

direct

energy

(see

section

on

adjustment

of

the

Direct

Energy

Control).

1.

POWER

REQUIREMENTS

The

Model

301

is

designed

to

be

powered

by

the

majority

of

the

fine

amplifiers

and

receivers

that

are

on

the

market

today.

Power

requirements

will

vary

substan-

tially

with

room

size,

speaker

placement,

and

type

of

music

played.

High

quality

sound

requires

less

than

10

watts

rms

per

channel,

although

amplifiers

rated

up

to

60

watts

rms

per

channel

may

be

used.

2.

WIRE

SELECTION

If

the

wires

to

your

speakers

are

less

than

30

feet

long,

18-gauge

zipcord

(two-conductor)

wire

is

recom-

mended.

If

30-

to

50-foot

lengths

of

wire

are

needed,

16-gauge

two-conductor

wire

should

be

used.

If

your

dealer

doesn't

provide

you

with

speaker

wire,

it

can

be

ob-

tained

at

most

hardware

stores.

Choosing

the

correct

wire

size

insures

that

the

wire

connecting

your

speakers

doesn't

have

too

much

resistance.

Excessive

re-

sistance

causes

audible

coloration

and

loss

of

power

with

all

speak-

ers.

3.

PHASING

It

is

important

that

the

connections

to

the

speakers

and

the

receiver

or

amplifier

be

the

same

for

both

channels

so

that

the

two

speakers

are

in

phase

with

each

other.

Refer

to

Diagram

5

as

you

do

the

following

steps:

1.

Start

with

the

speaker

marked

“Part

1”.

2.

Place

it

on

the

left

side

of

your

room.

3.

Locate

the

“POS”

and

“COM”

terminals

on

the

rear

of

the

speaker.

4.

Using

your

speaker

wire,

which

is

marked

to

distinguish

one

conductor

from

the

other

by

means

of

color

or

grooved

ridges,

connect

the

terminal

marked

“COM”

on

the

back

of

the

left

speaker

to

the

terminal

marked

“COM,”

“negative”

or

(-),

on

the

left

channel

amplifier

output.”

5.

Connect

the

“POS”

terminal

on

the

left

speaker

to

the

terminal

marked

“POS,”

“positive”

or

(+),

on

the

left

channel

output

of

the

amplifier

or

receiver.

6.

Place

the

speaker

marked

“Part

2”

on

the

right-hand

side

of

the

room

and

repeat

the

connection

procedure.

4.

FUSING

When

using

the

Model

301

with

amplifiers

rated

at

more

than

60

watts

rms

per

channel,

or

with

sinusoidal

or

other

test

signals,

we

recommend

that

the

speaker

be

protected

by

a

BUSS

MDL

1%-amp

“slow-blow”

fuse

(or

equivalent)

using

an

in-line

HDH

fuseholder

(or

equivalent)

wired

in

series

on

the

posi-

tive

side

of

each

speaker

cable.

The

fuse

will

also

provide

pro-

tection

against

speaker

damage

in

the

event

of

amplifier

failure.

“When

connecting

to

your

amplifier,

if

there

is

a

choice

of

imped-

ances

on

the

amplifier

output,

use

the

terminal

marked

“8”

or

“8

ohms.”

If

two

pairs

of

Model

301s

are

being

connected

in

parallel,

the

terminal

marked

“4”

or

“4

ohms”

on

the

receiver

or

amplifier

should

be

used.

C.

Adjustment

of

the

Direct

Energy

Control

The

Direct

Energy

Control

has

been

carefully

designed

to

provide

the

optimum

performance

of

the

Model

301

under

a

wide

range

of

listening

conditions.

This

control

primarily

affects

the

spatial

distri-

bution

of

high

frequencies

above

5

kHz.

At

distances

close

to

the

loudspeaker,

the

effect

of

the

control

on

high

frequency

energy

is

very

large,

reaching

15

dB

at

15

kHz.

However,

the

effect

decreases,

becoming

more

subtle,

with

increasing

distance

from

the

speaker

and

will

be

less

noticeable

in

larger

rooms,

where

the

listener

is

prin-

cipally

in

the

reverberant

field.

Under

most

listening

conditions,

critical

listeners

will

find

that

the

Direct

Energy

Control

provides

a

significant

aid

in

optimizing

the

performance

of

the

Model

301.

Please

note

that

the

numbers

which

appear

in

Diagram

6

are

for

reference

only

and

do

not

appear

on

your

speaker

system.

They

are

there

to

help

you

understand

the

positioning

required

for

optimum

performance

in

your

listening

environment.

In

the

diagram,

the

left

speaker,

when

starting

from

the

top

marking,

is

rotated

clockwise

for

increasingly

high

numbers.

The

right

speaker

is

rotated

counter-

clockwise

for

the

same

increase

in

reference

numbers.

The

following

guidelines

should

be

followed:

POSITIONS

1

АМО

2

These

positions

provide

the

maximum

direct

sound

energy

at

high

frequencies.

For

horizontal

placement

they

are

used

to

establish

high

frequency

balance

if

side

reflecting

walls

are

not

present

or

are

covered

with

sound

absorbing

material.

These

positions

provide

less

stereo

spread

than

higher

numbers

and

will

be

preferred

by

some

listeners

for

reproduction

of

soloists

and

small

ensembles.

Use

positions

1

and

2

for

vertical

placement

if

the

speaker

is

placed

higher

than

4

feet.

POSITION

3

This

is

the

normal

setting

of

the

Direct

Con-

trol.

This

position

is

used

for

horizontal

placement

when

a

side

re-

flecting

wall

is

located

near

the

side

of

the

speaker,

as

shown

in

is

placed

lower

than

4

or

within

2

These

positions

provide

minimum

frequencies

and

are

used

for

ment

if

a

reflecting

side

is

present.

Operation

in

Positions

4

and

5

will

provide

very

spacious

stereo

reproduction,

especially

suited

for

large

ensembles

such

as

an

orchestra

or

a

chorus.

D.

Room

Acoustics

The

sound

quality

of

loudspeakers

depends

on

many

environmen-

tal

factors

other

than

speaker

placement,

such

as

the

size,

shape

and

construction

of

the

room,

and

the

amount

and

type

of

furniture,

rugs

and

draperies

present.

A

lack

of

bass

response

frequently

may

be

attributed

to

walls

of

thin

panel

construction,

large

openings

(e.g.,

doorways),

or

excessive

window

glass,

which

allow

low

fre-

quencies

to

pass

through

rather

than

reflecting

them

into

the

room.

The

overly

bright

sound

of

acoustically

“live”

rooms

(e.g.,

those

can

be

improved

by

the

addition

of

rugs

and

heavy

draperies,

which

also

serve

to

eliminate

echoes

and

standing

waves.

For

acous-

tically

“dead”

rooms

(e.g.,

those

with

wall-to-wall

carpets,

heavily

upholstered

furniture,

large

amounts

of

draperies),

furnishings

should

be

arranged

so

that

speakers

have

unobstructed

sound

transmission

paths

to

the

listening

areas.

Finally,

since

no

room

is

acoustically

perfect,

you

are

encouraged

to

use

your

amplifier

or

receiver

tone

controls

to

adjust

the

sound

for

your

maximum

listening

enjoyment.

IN

CASE

OF

DIFFICULTY

If

you

suspect

a

problem

with

one

of

your

Model

301

speakers,

it

is

worth

a

few

minutes

of

your

time

to

determine

whether

the

de-

fect

is in

your

speaker

or

in

some

other

portion

of

your

high

fidelity

system.

IF

ONE

SPEAKER

SOUNDS

DEFECTIVE,

first

disconnect

the

speaker

that

is

operating

properly

by

disconnecting

the

wire

from

the

output

terminals

on

the

rear

of

the

amplifier.

Next,

disconnect

the

wire

running

to

the

speaker

which

sounds

de-

fective

and

connect

it

to

the

output

terminals

of

the

amplifier

channel

which

you

are

sure

is

operating

properly.

If

the

speaker

now

seems

to

be

operating

properly,

the

defect

is

in

another

part

of

your

hi-fi

system.

IF

THE

TROUBLE

APPEARS

IN

BOTH

CHANNELS,

connect

your

Model

301s

to

another

amplifying

source

or

high

fidelity

system

that

is

operating

properly.

If

the

trouble

is

no

longer

apparent,

the

difficulty

is

not

with

the

speakers.

IF

THE

TROUBLE

PERSISTS

ІМ

ONE

ОВ

BOTH

SPEAKERS,

con-

tact

your

dealer.

He

will

verify

the

defect

and

will

arrange

for

serv-

ice

either

at

our

factory-authorized

service

or

by

the
