Do you have a question about the Boston Acoustics CR57 and is the answer not in the manual?
Ensure correct wiring by connecting positive to positive and negative to negative terminals.
Use 18-gauge wire up to 18ft, and 16-gauge wire for longer runs for optimal performance.
Position speakers for optimal soundstage, typically 6-12 ft apart for stereo and flanking the TV for home theater.
Place surround speakers above ear level on side walls behind the listening position for best results.
Keep speakers at least 18 inches from room corners to avoid unnatural bass reinforcement.
Use the included rubber feet for stable placement on stands or shelves.
Consult an installer for wall mounting using appropriate hardware and screws between % and %-inch.
Attach the optional stand-off/swivel bracket to the speaker for versatile mounting.
Rotate the CR grille logo 90° for horizontal mounting or to maintain symmetry.
Avoid distorted signals to prevent damage; turn down volume if harsh noise is heard.
Contact your dealer or Boston Acoustics for any necessary service or support.
