Installation

Install

the

woofer

wherever

you

like

because

with

the

bass

sound

range

reproduced

from

the

woofer

(below

150

Hz),

human

hearing

cannot

detect

the

direction

and

position

in

which

the

sound

is

being

produced.

Also,

since

the

feeling

of

stereo

is

lost

with

bass

frequencies,

a

single

woofer

is

enough

for

reproducing

the

bass

of

stereo

channels.

To

obtain

a

better

bass

reproduction,

we

recommend

that

you

install

the

woofer

on

a

solid

floor

where

resonance

is

unlikely

to

occur.

Notes

¢

Always

install

the

woofer

vertically,

keeping

a

few

centimeters

from

away

the

wall.

¢

Do

not

place

an

object

on

the

woofer

or

sit

on

it.

¢

If

the

woofer

is

installed

in

the

center

of

a

room,

the

bass

could

be

extreamely

weakened.

This

is

due

to

the

influence

of

the

standing

wave

of

the

room.

If

this

happened,

move

the

woofer

away

from

the

center

of

a

room

or

eliminate

the

cause

of

the

standing

wave,

by

installing

a

bookshelf

on

the

wall,

etc.

Precautions

On

safety

¢

Before

operating

the

woofer,

be

sure

that

the

operating

voltage

of

your

woofer

is

identical

with

that

of

your

local

power

supply.

Unplug

the

extended

period

of

time.

To

disconnect

the

cord,

pull

the

cord

by

grasping

the

plug.

Never

pull

the

cord

itself.

Should

any

liquid

or

solid

object

fall

into

the

woofer,

unplug

the
