Frequently Asked Questions and Troubleshooting 9

How do I clean my speakers?

Just use a dust free cloth or a soft brush to remove the

dust from your speakers. We recommend a specialty

cloth (available at the Xtatic shop at www.martinlogan.

com) that cleans your speakers better than anything

else we have tried. Do not spray any kind of clean-

ing agent on or in close proximity to the drivers.

What size amplifier should I use?

We recommend an amplifier with 100 watts per channel

for most applications. Probably less would be ade-

quate when used in home theater where a subwoofer

is employed.

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 perfor-

mance 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.
