Frequently Asked Questions
How do I clean my speakers? 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 grille 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 con-
trol (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 problem 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 (–)?
• The use of optional back boxes will reduce the bass output of the speaker as these
enclosures reduce the air space the woofer is able to utilize. This is the tradeoff of reducing
unwanted sound that is able to travel to other areas of the home.
