• Before connecting the speakers, disconnect your 

amplifier’s power cord from the wall outlet and set its 
volume control to minimum.

• The speaker’s rated impedance is 4

 

Ω

 

. Make sure you con-

nect an amplifier that is compatible with a 4

 

Ω

 

 impedance.

• Use the supplied speaker cables to connect the speak-

ers to your amplifier as shown.

The type of speaker terminals used on the receiver and 
their position depends on the model. Refer to the 
receiver’s instruction manual for details on connecting 
speakers to the receiver.

 

• Make sure the speaker’s positive (+) terminals are 

connected to the amplifier’s positive (+) terminals, 
and the speaker’s negative (–) terminals are con-
nected to the amplifier’s negative (–) terminals. If you 
get the polarity reversed, the sound will be unnatural, 
with a limited bass range and poor stereo image.

• Make sure that the positive (+) and negative (–) wires 

are not touching each other. If they are, a short circuit 
may occur, damaging your amplifier.

The sound quality of the speakers is directly affected by 
the size and shape of the room they’re used in and its 
furnishings. When considering where to place your 
speakers, read the following:
• Where possible, mount the speakers on speaker 

stands, concrete blocks, bricks, or a sturdy bookshelf. 
Putting them directly on the floor will emphasize bass 
sounds, creating a boomy sound.

• If a speaker is placed on an uneven surface where it 

can wobble or vibrate, bass performance will be 
adversely affected. You can eliminate speaker wobble 
by putting a shim made out of cork or metal, such as a 
coin, underneath the speaker or stand, as shown.

• If you mount the speakers on a flat surface, such as a 

bookshelf, you can improve the sound quality by 
inserting cork spacers or coins in between the speaker 
and the shelf. Raising them off the surface like this 
will reduce the contact area and improve the sound.

• If you like lots of bass, mount the speakers on low 

speaker stands and place them in front of a solid wall. 

• Walls and furnishings affect sound quality. To achieve 

a good stereo sound, put the left and right speakers in 
similar locations at the same distance away from your 
listening position and at the same height. If you put 
them in totally different locations, for example, one 
on the floor and the other on a bookshelf, the stereo 
imaging will be adversely affected.

• To determine the best positions for your speakers, 

imagine an equilateral triangle and put the left and 
right speakers at the ends of the base. The ideal listen-
ing position is at or slightly behind the triangle’s 
apex. Angle the speakers toward your listening posi-
tion.

• Glass doors and smooth walls behind the listening 

position can reflect the sound from the speakers and 
can make sounds at certain frequencies louder. You 
can prevent this by hanging sound-absorbing mate-
rial, such as thick curtain, on the door or wall.

 

• Please note that the speakers’ surface features a spe-

cial finish. An object placed on the speakers for a 
long period of time may leave a trace or mark. Adhe-
sive tape may also leave a mark.
