T H E C O M P A C T R E F E R E N C E S E R I E SThe Compact Reference Series incorporates the highest quality materials, the latest acoustic technology, and new

state-of-the-art molding techniques, and are capable of unusually high performance. These speakers are fully

compatible with home theater systems. Each model features MagnaGuard® magnetic shielding. This ensures the

speaker ‘s magnetic field will not distort the TV‘s image or damage the picture tube, allowing placement next to a

television or computer monitor.

H O W T O C O N N E C T Y O U R S P E A K E R SCorrectly wiring your speakers is important for achieving the best sound quality and a rich stereo image. Wiring

should take just a few minutes, but it‘s important to do it carefully, since incorrect wiring (such as reversed

connections) can result in a poor stereo soundstage or poor bass.

We recommend 18 gauge wire or thicker for runs up to 25 feet (8 meters) and 16 gauge wire or thicker for longer

runs. Separate the first few inches of the wire conductors. Strip off 1/2-inch (12mm) of insulation from the ends of each

speaker wire to expose the two conductors and tightly twist the wire strands.

Using the five-way

binding posts: The

binding posts permit

easy connection to

banana plugs, spade

lugs, and bare wire.

The metal surfaces are

plated with 24k gold

to prevent corrosion.

C H E C K I N G T H E C O N N E C T I O N SIt is critical that your speakers are hooked up with similar polarity or “in phase.” A simple listening test will tell you if

the speakers are connected properly. Place the speakers face-to-face, as close as possible. While listening to music

with your amplifier set to MONO, reverse the connections at one speaker only. You’ll hear a dramatic change in

sound. The connection that yields the fuller bass and louder sound is the correct one.

Warning: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections to

the speaker.

H O O K U PWhen making all connections, be sure to connect + to +

(red) and – to – (black). Connect the speaker terminals to

the amplifier speaker outputs.

Important: Typically, one side of

the wire is smooth. Connect this

side to the – (black) connection.

The other side has a rib or stripe.

Connect this to the + (red)

connection.

You may wall-mount the CR6 and CR7 with either the keyhole built into the back

panel or the optional CRB bracket.

Using the keyhole– Consult a knowledgeable installer regarding the proper

hardware to use on your wall surface. Make certain there is at least a 1/2 - inch

(12mm) gap between the top rear of the speaker cabinet and the wall behind it.

This will ensure the speaker is the proper distance from the wall to maintain

unrestricted air flow from the woofer port.

Using the optional CRB bracket– Wall mounting brackets (model ”CRB”)

are available for the CR6 and CR7. The brackets provide greater mounting

flexibility than the keyhole and will position the speaker the proper distance from

the wall. For more information, contact your dealer or Boston Acoustics directly.

R O O M P L A C E M E N T F O R B E S T R E S U L T SRoom placement is one of the most important factors in determining sound quality. Taking a few minutes to try different

placements ensures that your speakers will sound best in your listening environment.

For a realistic soundstage, place the speakers 6 to 12 feet (2-4m) apart so they form a triangle with your favorite

listening position, and are near ear level when you are in a seated position. The speakers should be at least 2 feet (.6m)

from the corners of the room. Putting the speakers too close to a corner can produce an unnatural bass reinforcement that

detracts from their balanced, uncolored sound. If a speaker must be placed near a corner, move it away from the wall

behind it to preserve its natural tonal balance.

The CR Series will work well on bookshelves or stands. For best results, avoid placing the speaker’s back flush against

a wall, since this will restrict the air flow from the port and reduce the bass response. Clearance of 1/2 - inch (12mm) or more

is sufficient to maintain proper bass response.

Four self-adhesive rubber feet are provided to protect the mounting surface finish and prevent vibration.

L I S T E N I N G L E V E L S A N D P O W E R H A N D L I N GThe power recommendation for the Compact Reference Series assumes you will operate the amplifier in a way that will not

produce distortion. Even these rugged systems can be damaged by an amplifier if it is producing distortion.

If you hear a harsh, gritty noise, turn the volume down. Prolonged or repeated operation of your speaker with a

distorted signal from the amplifier can cause damage that is not covered by the warranty.
