with

your

BOSE

901

Loudspeakers

If

you

decide

to

hang

your

speakers,

place

the

Part

II

speaker

on

the

left

side

of

the

room

and

the

Part

I

speaker

on

the

right

side

of

the

room.•

Turn

the

speakers

upside

down

and

place

them

on

a

covered

surface

or

rug.

•Please

note

that

the

reversed

speaker

placement

is

intentional

and

is

necessary

when

using

electronics

products

to

be

introduced

by

BOSE

to

operate

with

the

center

terminal

found

on

the

901

Series

THREE

-CHAIN

OR

FOUR

-CHAIN

MOUNTING

Three

-chain

mounting

utilizes

the

holes

(8)

near

the

front

of

the

cabinet,

and

a

third

pilot

hole

located

near

the

"V"

of

the

cabinet.

When

suspending

the

speaker

with

four

chains,

use

the

tour

predrilled

holes

(C)

located

near

the

corners

of

the

speaker.

Insert

four

3

4

-inch

eyehooks

in

place.

The

speaker

system

weighs

35

pounds

and

care

should

be

taken

to

ensure

that

the

speaker

is

safely

supported

from

the

ceiling.

A

supporting

chain

should

be

attached

to

a

structural

support,

such

as

a

beam

or

joist.

If

you

have

placed

the

speakers

quite

high

in

your

listening

room,

the

sound

can

be

directed

downward

by

angling

the

rear

of

the

speaker

down.

The

sound

will

be

directed

downward

after

it

is

reflected

off

the

rear

wall.

This

is

done

by

increasing

the

length

of

the

rear

chain(s)

holding

the

speaker

system

in

place.

INSTALLING

THE

RUBBER

FEET

The

speaker

is

supplied

with

four

rubber

feet

and

four

screws.

These

feet

should

be

used

to

prevent

possible

damage

to

sur-

faces

such

as

shelves

or

tables.

Insert

the

feet

with

the

screws

in

the

four

holes

(C)

located

near

the

corner

of

the

cabinet.

ROOM

ACOUSTICS

The

acoustical

properties

of

the

room

(such

as

the

size,

shape,

construction,

and

furnishings)

play

an

important

part

in

the

quality

of

sound

produced

by

your

high-fidelity

system.

A

lack

of

bass

response

frequently

may

be

attributed

to

walls

of

thin

panel

construction,

large

openings

(e.g.,

doorway),

or

excessive

window

glass,

which

allow

low

frequencies

to

pass

through

rather

than

reflecting

them

into

the

listening

room.

The

overly

bright

sound

of

acoustically

"live"

rooms

(e.g..

those

with

uncovered

floors

or

scatter

rugs,

small

amounts

of

furniture,

hard

walls)

can

be

improved

by

the

addition

of

rugs

and

heavy

drapery,

which

also

serve

to

eliminate

echoes

and

standing

waves.

For

acoustically

"dead"

rooms

(e.g.,

rooms

with

wall-to-wall

carpeting,

heavily

upholstered

furniture

and

draperies,)

furnishings

should

be

rearranged

or

removed.

The

unique

controls

on

your

901

IV

Equalizer

are

especially

helpful

in

compensating

for

the

characteristics

of

different

rooms.
