Frequently Asked Questions

How do I clean my speakers? Just use a dust free cloth or a soft brush to remove the dust
from your speakers. Do not spray any kind of cleaning agent on or in close proximity
to the drivers.
What size amplifier should I use? We recommend an amplifier rated within the suitable
amplifier range of your speaker.
Could you suggest a list of suitable electronics and cables that would be ideal for
MartinLogan speakers? The area of electronics and cable choice is probably the most
common type of question that we receive. It is also the most subjective. We have
repeatedly found that brands that work well in one setup will drive someone else nuts in
another. We use many brands with great success. Again, we have no favorites; we use
electronics and cables quite interchangeably. We would suggest listening to a number
of brands—and above all else—trust your ears. Dealers are always the best source for
information when purchasing additional audio equipment or cables and will be well
versed in the subject of special safety requirements for in-wall cable.
Will exposure to sunlight affect the life or performance of my speakers? We
recommend that you not place any loudspeaker in direct sunlight. The ultraviolet (UV) rays
from the sun can cause deterioration of grill cloth, speaker cones, etc. Small exposures to
UV will not cause a problem. In general, the filtering of UV rays through glass will greatly
reduce the negative effects.

Troubleshooting

No Output
• Check that all your system components are turned on, not muted, and that your
balance control (if applicable) is set correctly.
• Check to make sure your power outlet at the wall is working.
• Check your power cords, speaker wires, and interconnecting cables.
• Check to make sure no headphones are plugged in.
• Swap speaker wires at your amplifier with those of a speaker that is functioning
correctly. If the lack of output moves to a different speaker the problem could be
with other equipment in your system (i.e. amp, pre-amp, processor, etc.)
• Try hooking up a different set of speakers. The lack of output could point to a prob-
lem with other equipment in your system (i.e. amp, pre-amp, processor, etc.)
Lack of Bass or Poor Imaging
• Check your speaker wires. Is the polarity correct — (+) to (+) and (–) to (–)?
