The diaphragm material used in all Martin-Logan
speakers employs an extremely sophisticated vapor
deposited conductive polymer membrane. A proprietary
conductive compound is vaporized then electrostatically
driven into the surface of the polymer film in a vacuum
chamber. This process allows an optically transparent
membrane, adds no mass to the diaphragm and is
extremely uniform in its surface resistivity characteristics.
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.

All Martin-Logan transducers begin with two pieces of
high grade, cold rolled steel. These steel pieces are then
custom perforated and insulated with an exotic composite
coating. This proprietary coating insulates the stator to 3
times its actual needed working voltage and gives the
Stylos a wide margin of safe operation. In addition to the
electrical insulation properties, this coating also provides
the Stylos with a durable, attractive finish that dampens
the steel to prevent ringing. The finished metal plates are
curved into a 30 degree arc. Placed between them is our
exclusive vapor deposited diaphragm and spacers. This
assembly is then bonded together with aerospace
adhesives whose strength is so great that it is commonly
used as an alternative to welding.
The result of these advanced technologies is a trans-
ducer that is attractive, durable, highly rigid, well damp-
ened, and neutral.

The clear Lexan
®
panels on the back of the Stylos stator
are the key elements of an innovative pressure compen-
sation technology. Martin-Logan is able to tone-shape the
diaphragm + or - 6dB without the use of an insertion loss
crossover. The advantage of this system is a high
efficiency driver with wide bandwidth capabilities of
dimensions which are easily integrated into a domestic
environment.

Since the beginning of audio, achieving smooth full range
dispersion has long 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 electrostatics have always been one of the
most complex 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, Martin-Logan 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, we developed the production
capability to bring this technology out of the laboratory
and into the market place.
You will find this proprietary Martin-Logan technology
used in 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 all Martin-Logan products.
