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. The high voltage on the stators is fully insulated The
electrostatic diaphragm has high voltage with low current
and is not dangerous. As a matter of fact, the voltage in
our electrostatic diaphragm is 10 times less than the static
electricity that builds up on the surface of a CRT televi-
sion 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.
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.
