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 character 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 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 sou
rce
for information when purchasing
additional audio equipment.
Will my electric bill go ‘sky high’ by leaving my
speakers plugged in all the time?
No. There is circuitry to turn off the static charge
when not in use. Power consumption will be
reduced when in standby. This also prevents dust
collection on the electrostatic element.
If the diaphragm is punctured with a pencil or
similar 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 per-
formance 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.
Will excessive smoke or dust cause any
problems with my electrostatic speakers?
Exposure to excessive contaminants such as smoke
or dust may potentially affect the performance
of the electrostatic membrane, and may cause
discoloration of the diaphragm membrane. When
not in use for extended periods, you should unplug
the speakers and cover them with the plastic bags
in which the speakers were originally packed. It is
a good idea to vacuum the electrostatic portion of
each speaker three or four times a year. See the
vacuuming FAQ.
A problem has recently developed with my
MartinLogan speakers . The speaker seems to
be hissing even when the amplifier and such are
not connected . I was wondering if this sounds
like any problem you have encountered previ-
ously and have a simple solution for or might it
be something which will need to be looked into
more carefully .
Your speakers are dusty. See the vacuuming
FAQ. The electrostatic charge on the element has
attracted airborne dust or pollen. Since 1993, all
of our speakers have been built with a charging
circuit board that only charges the electrostatic
element when music plays. At other times they
are not charged and cannot collect dust. You can
get the same benefit by simply unplugging them
