Maintenance and Service
All wiring connections should be inspected and cleaned or remade at least once a year.
If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one loudspeaker, rewire that speaker in a different location within the system. Should the problem persist then the problem is within the speaker. If the speaker sounds fi ne in the new position it is a strong indication of a more in depth issue with the electronics in the system. In the event that your speakers ever need service, contact your local Boston Acoustics dealer or visit www.bostonacoustics.com/dealers for a list of dealers in your area.
