Connecting the Speakers

•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 4Ω. Make sure you con- nect an amplifier that is compatible with a 4Ω 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.

Before Turning on Your 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.

Speaker Placement

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.

Shim

•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.
