Installation

Since

the

human

ear

cannot

detect

the

direction

and

position

where

the

bass

sound

being

reproduced

by

a

woofer

(below

150

Hz)

comes

from,

you

can

install

the

woofer

wherever

you

like

in

your

room.

To

obtain

a

better

bass

reproduction,

we

recommend

you

to

install

the

woofer

on

a

solid

floor

where

the

resonance

is

unlikely

to

occur.

You

can

obtain

a

sufficient

heavy

bass

reproduction

from

a

single

woofer.

However

if

you

use

a

couple

of

the

woofers,

you

can

obtain

an

even

more

effective

heavy

bass

reproduction.

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.

e

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.
