Humming, buzzing or rattling noise heard from product | Acoustimass® 5 Series IV speaker system
If you hear an unexpected noise from your product:
Try the following:
Be sure the speaker is actually rattling, and that the problem is not distorted sound.
If the problem is distortion, see Poor sound quality from product.
Be sure the rattling noise is not something on or near the system.
A loose item on or near the system may be vibrating when certain frequencies or volume levels are played. Secure any loose items or move the system or items to another location if the system sound is causing nearby items to rattle.
If it sounds like something is loose inside your speaker
Your speaker shouldn’t have any loose parts inside. If you think something is loose, click 'Start a repair or replacement' at the bottom of the page to check your options.
Be sure the system is set up properly and all connections are secure.
A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.
Check the condition of the speaker wires and be sure they are secure at both ends.
Check the speaker wires for any kinks, scratches, cuts or damage. Replace any damaged wires and check that they are securely connected at both ends.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
