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.
