We recommend an amplifier with 100 to 200 watts per
channel for most applications. The Sequel II will perform
well with either a tube or transistor amplifier, and will
reveal the sonic character of either type.

No. The Sequel II's impedance characteristics do not
require that a high current amplifier be used. However,
it is important that the amplifier be stable operating into
varying impedance loads.

Yes. Or before. It’s a good idea to disconnect all of your
audio/video components during stormy weather.

Actually, there is less interaction between a television
and an electrostatic speaker than between a television
and a conventional system. The magnets in conventional
speakers do interact with televisions tubes. However, we
do recommend that you keep your speakers at least one
foot away from the television because of the dynamic
woofer they employ.

No. A pair of Sequel II's draw about 5 watts maximum.

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.

Our research department has literally punctured hun-
dreds 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, replac-
ing the electrostatic transducer will be the only solution.

We recommend that you not place your Sequel II's in
direct sunlight as the ultraviolet (UV) rays from the sun can
cause deterioration of grill cloth, speaker cones, etc.
However, small exposures to UV will not cause a problem.

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 they were originally packed in.
