Room Placement For Best Results; Wall Mounting Speakers; Listening Levels And Power Handling - Boston Acoustics CR6 User Manual

R O O M
Room 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
is sufficient to maintain proper bass response.
Four self-adhesive rubber feet are provided to protect the mounting surface finish and prevent vibration.

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
(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.

The 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.
