12 Frequently Asked Questions and Troubleshooting
FREQUENTLY ASKED QUESTIONS AND TROUBLESHOOTING
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 ATF
element.
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. Our hybrid designs will perform well with
either a tube or transistorized amplifier, and will reveal
the sonic character of either type. However, it is impor-
tant that the amplifier be stable operating into varying
impedance loads: a stable amplifier will be able to
deliver twice its rated wattage into 4 Ohms and should
again double into 2 Ohms.
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.
