The

BOSE

Model

601

speaker

system

incorporates

two

eight

-

inch

woofers,

four

three-inch

tweeters.

a

tuned

port

enclosure.

and

a

unique

new

Symmetry

Control

providing

outstanding

flex-

ibility

and

performance

in

your

listening

room.

(See

Figure

This

system's

two

eight

-inch

woofers

(one

facing

the

front

grille

and

another

radiating

through

the

acoustically

transparent

top

.

grille)

provide

outstanding

bass

response

while

simultaneously

providing

a

balance

of

reflected

and

direct

sound.

Four

identical

tweeters

are

used

in

the

Model

601

speaker

system

to

simulate

the

distribution

of

sound

energy

normally

associated

with

live

performances.

Radiating

sound

through

both

the

front

and

the

acoustically

transparent

top,

the

tweeter

system

"crossfires"

the

high

-frequency

energy

via

the

reflect-

ing

walls

of

your

listening

room.

This

unique

design

provides

multiple

sound

reflections

creating

a

sense

of

spaciousness

with

a

strong

center

image.

The

Model

601

crossover

network

incorporates

a

unique con-

trol

that

modifies

the

spatial

performance

of

the

speaker.

Unlike

most

crossover

controls

that

change

the

tonal

balance

of

the

speaker,

the

601's

Symmetry

Control

is

designed

to

affect

the

spatial

characteristics

of

the

speaker,

while

leaving

the

tonal

balance

unchanged.

The

Symmetry

Control

has

two

settings,

"Asymmetric"

and

"Symmetric."

In

the

"Asymmetric"

position,

the

Model

601

loudspeaker

pro-

duces

optimum

spatial

performance

using

the

reflecting

walls

of

your

listening

room.

If

not

all

necessary

reflecting

surfaces

are

present,

the

Symmetry

Control

can

be

adjusted

to

the

"Symmetric"

position.

The

601

speaker

system

is

designed

in

mirror

-image

pairs

with

each

speaker

providing

either

"Symmetric"

or

"Asymmetric"

sound

radiation

depending

upon

the

position

of

the

Symmetry

Control.
