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 or cloth covers 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.
Could my children, pets, or myself be shocked by the
high-voltage present in the electrostatic panel?
No. High voltage with low current is not dangerous. As a
matter of fact, the voltage in our speakers is 10 times less
than the static electricity that builds up on the surface of
your television screen.
How do MartinLogan speakers hold up over a long term in
the humidity of tropical climates?
We should tell you that MartinLogan indeed has a very
substantial number of customers in tropical regions of
the world. Our speakers have been serving them nicely
for many years. This concern may have come from our
earlier design of speakers, which were charged continu-
ously. Since 1993, all of our speakers have been designed
so that they only charge the panel while music is being
played. This improvement has made a tremendous differ-
ence in the consistent performance of our product. There
may be a little more maintenance involved in humid
regions when not in an air conditioned environment.
Simply enough, the concern is to keep the electrostatic
panels dust free. Humidity will combine with any dust on
the panel to make it slightly conductive. This will result
in a slight pathway for the charge to leave the membrane
of the speaker. The solution is simple. They only require
occasional vacuuming with a strong vacuum hose.
How do I vacuum my MartinLogan speakers?
Vacuuming will be most effective if the speakers have
been unplugged for six hours to twelve hours (or over-
night). You need not worry about the vacuum pressure
damaging the "delicate" membrane. It is extraordinarily
durable. Dirt and dust may be vacuumed off (don’t use a
brush attachment) or you may blow them off with com-
pressed air. When vacuuming or blowing off your panels
do so to both sides, but focus the majority of your atten-
tion on the front of the panels.
Should I unplug my speakers during a thunderstorm?
Yes, or before. It’s a good idea to disconnect all of your
audio/video components during stormy weather.
