MartinLogan SCRIPT i, User Manual

Page: 17 / 28

Since the beginning of audio, achieving smooth dispersion
has been a problem for all loudspeaker designers. Large
panel transducers present even more of a challenge because
the larger the panel, the more directional the dispersion
pattern becomes.
Full range electrostats have long been one of the most prob-
lematic transducers because they attain their full range
capabilities via a large surface area. It looked as if they were
in direct conflict to smooth dispersion and almost every
attempt to correct this resulted in either poor dispersion or
a serious compromise in sound quality.
After extensive research, MartinLogan engineers discovered
an elegantly simple solution to achieve a smooth pattern
of dispersion without degrading sound quality. By curving
the horizontal plane of the electrostatic transducer, a
controlled horizontal dispersion pattern could be achieved,
yet the purity of the almost massless electrostatic diaphragm
remained uncompromised. After creating this technology,
MartinLogan developed the production capability to bring it
out of the laboratory and into the market place.
You will find this proprietary MartinLogan technology used
in almost all of our products. It is one of the many reasons
behind our reputation for high quality sound with practical
usability. This is also why you see the unique “see through”
cylindrical shape of MartinLogan products.
MicroPerf Stator
The MicroPerf stator design reduces the size of individual
holes in a stator, allowing more openings per square inch
than a standard MartinLogan stator. This maximizes efficiency
and dispersion of small stat panels and also increases opti-
cal clarity. In addition, the tighter grid of holes permits the
MicroPerf stator to drive the diaphragm accurately.
The diaphragm in the Script i employs an extremely sophisti-
cated conductive coating that has been applied to the
polymer surface at an atomic level using a plasma bonding
process. A proprietary compound is driven into the surface
of the polymer film in an oxygen free argon chamber. This
process allows extremely uniform surface resistivity character-
istics, an optically transparent surface and adds no mass to
the diaphragm. This uniform surface resistivity controls the
electrostatic charge on the diaphragm surface and regulates
its migration. As a result, no discharging or “arcing” can occur.
Transducer Integrity
All MartinLogan transducers begin with two pieces of high-
grade, cold rolled steel. These steel pieces are then custom
perforated and insulated with a unique composite coating.
This proprietary coating insulates the stator to three times
its actual needed working voltage and gives the Script i a
wide margin of safe operation. In addition to the electrical
insulation properties, this coating also provides the Script i
with a durable, attractive finish that dampens the steel to
prevent ringing. These pieces then sandwich a proprietary
diaphragm and spacers into a curved geometry, and bond
together with aerospace adhesives whose strength exceeds
that of welding.The result of these advanced technologies
is a transducer that is attractive, durable, highly rigid, well
dampened, and neutral.
Low Voltage Power
To eliminate the need for a traditional IEC power cord and
broaden ease of installation, especially for custom installers,
the Script i features a low-voltage power supply.
