22 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. We also recommend a specialty
cloth (available at the Xtatic shop at www.martinlogan.
com) that cleans your speakers better than anything
else we have tried. For the wood surfaces it is accept-
able to slightly dampen the cloth. Do not spray any
kind of cleaning agent on or in close proximity to
the electrostatic element. Avoid the use of ammonia
based products or silicone oil on the wood parts.

What is the advantage of ESL?
Since the diaphragm is uniformly driven over its entire
surface—unlike a tweeter that is only driven at its
edges— it is the only technology that can be made
large enough to play bass, yet is still light enough for
high frequencies. This unique property allows for the
elimination of high frequency crossover points and
their associated distortions.

What size amplifier should I use?
We recommend an amplifier with 100 to 200 watts
per channel for most applications. Probably less would
be adequate for our smaller hybrids or 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 char-
acter of either type. However, it is important that the
amplifier be stable operating into varying impedance
loads: an ideally stable amplifier will typically be able
to deliver nearly twice its rated wattage into 4 Ohms
and should again increase into 2 Ohms.

Could you suggest a list of suitable electronics and
cables that would be ideal for MartinLogan speakers?
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.

Is there likely to be any interaction between my speakers
and the television in my Audio/Video system?
and the television in my Audio/Video system?
Actually, there is less interaction between a television
and an electrostatic speaker than between a television
and a conventional system. However, we do recommend
that you keep your speakers at least one foot away
from the television because of the dynamic woofer they
employ. In the case of our center channel speakers,
however, they are fully shielded and can go anywhere.

Will my electric bill go ‘sky high’ by leaving my speak-
ers plugged in all the time?
ers plugged in all the time?
No. A pair of MartinLogan’s will draw about 5 watts
maximum. There is circuitry to turn off the static charge
when not in use; however, actual consumption will
remain close to the same. The primary purpose of the
sensing circuitry is to prevent dust collection on the elec-
trostatic element.

If the diaphragm is punctured with a pencil or similar
item, how extensive would the damage to the speaker be?
item, how extensive would the damage to the speaker be?
Our research department has literally punctured hundreds
of holes in a diaphragm, neither affecting the quality of
the sound nor causing the diaphragm to rip. However,
you will be able to see the actual puncture and it can
be a physical nuisance. If this is the case, replacing the
electrostatic transducer will be the only solution.

Will exposure to sunlight affect the life or performance
of my speakers?
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 on the electrostatic
membrane itself.
