Frequently Asked Questions

How do I clean my speaker? See “Cleaning and Protecting Your Investment” on

page 3 of this manual.

What size amplifier should I use? We recommend an amplifier rated within the suit-

able 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 num-

ber 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 recom-

mend that you not place any loudspeaker in direct sunlight. The ultraviolet (UV) rays

from the sun can cause deterioration of speaker cones, etc. For installation of an all-

weather speakers we recommend as little direct sunlight as an installation will allow.

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. 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.)

Lack of Bass or Poor Imaging

• Check your speaker wires. Is the polarity correct — (+) to (+) and (–) to (–)?
