to

be

sure

all

connections

are

made

positive

to

positive

(+

to

+)

and

negative

to

negative

(-

(Figure

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

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.
