Bose 501 Series II Owner's guide - Page 4

The

guidelines

listed

below

should

be

followed

in

placing

the

501

speakers

relative

to

other

surfaces

in

the

room.

The

basic

idea

is

to

provide

space

around

the

speakers

to

allow

sound

waves

to

disperse

properly.

1.

The

speaker

should

be

no

closer

than

eighteen

inches

from

the

side

wall

or

from

openings

into

adjacent

rooms.

2.

Speakers

should

be

eighteen

inches

from

nearby

massive

objects

such

as

bookcases,

cabinets,

or

other

large

pieces

of

furniture.

3.

The

501

speaker,

although

designed

to

be

placed

against

the

wall,

can

be

moved

out

from

the

wall

a

maximum

distance

of

one

foot.

4.

Separation

between

the

speakers

should

be

between

four

and

fifteen

feet.

Best

results

will

be

obtained

with

a

separation

of

six

to

twelve

feet.

Fig.

Speakers

placed

in

a

listening

room

filled

with

sound

absorbing

material

(particularly

heavy

cushioned

furniture.

drapes,

and

carpets)

will

occasionally

produce

a

sound

lacking

in

brightness

(loss

of

high

frequencies).

Often

proper

balance

will

be

restored

by

placing

the

speaker

on

a

low

stand

(6

to

12

inches

high).

This

will

raise

the

tweeters

clear

of

nearby

obstructions,

additionally

aiding

dispersion

of

high

-frequency

sound.

B.

Connecting

the

Speakers

1.

Selecting

the

Speaker

Wire

If

the

wire

chosen

for

connecting

the

speakers

to

your

amplifier

has

too

much

resistance,

audible

colora-

tion

of

the

sound

and

loss

of

power

can

result.

The

table

below

summarizes

the

permissible

wire

length

for

18, 16,

and

14

gage

two

-conductor

wire

for

your

501

speaker

system.

Copper

zipcord

wire

is

readily

available

at

most

electrical

and

hardware

stores.

This

wire

usually

has

a

ribbed

line

running

along

one

of

the

conductors

so

that

the

conductors

can

be

identified

at

each

end

for

obtaining

the

proper

phasing

of

your

BOSE

501s.
