maintenance
The drivers require no routine maintenance. Do not let anything touch the drivers. Do not vacuum clean the drivers or front panels of the speakers. Some dust accumulation on the drivers is normal and does not affect the sound in any way. Heavy dirt buildup may be carefully removed with a soft paintbrush if necessary.
The enclosures of your a/d/s/ speakers require no maintenance other than dusting. Dust the speakers with a dry or slightly damp cloth. To clean the grills, remove them from the speaker and vacuum them. Do not vacuum the grille while they are on the speakers.
Most difficulties with high fidelity equipment result from loose or poor connections, bad connecting cables or switches in the wrong positions.
No sound It is rare for a speaker to fail completely. When there is no sound, check all the speaker wire connections and the setting of the amplifier’s tape monitor or speaker selector switch.
Dull or muted sound Operating the speakers at an unsafe power level activates the automatic tweeter protector. Turn down the amplifier volume control and the protector will automatically restore signal to the tweeter. Also check the amplifier’s tone controls or “high filter” switch.
Distorted Sound Distortion at moderate levels can be caused by loose connections, or stray wire strands shorting out adjacent wires at the amplifier or speaker terminals. If you hear distortion or any type of buzzing or rattling sound from an individual driver, contact your a/d/s/ dealer. Distortion at high levels is the result of either reaching the power limit of the amplifier or of the speaker. Turn down the volume to prevent damage.
Noise or Hum Continuous background noise or hum are always from the electronic equipment and not from the speakers.
