Polarity Control
(0° or 180°): Selects regular (0°) or inverted (180°) phase for the subwoofer. Set this switch to provide the fullest, most
dynamic bass. The e ect of phase will be most audible on low-frequency percussion instruments or music with a continuously
repeating bass line.
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 di erent location within the system. Should the problem persist then the problem is
within the speaker. If the speaker sounds 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.
