MARTINLOGAN EXCLUSIVES
XStat Transducer
XStat transducers incorporate a myriad of technology and
design innovations including CLS, MicroPerf, Generation 2
Diaphragms, ClearSpars™, and Vacuum Bonding.
CLS (Curvilinear Line Source)
Since the beginning of audio, achieving smooth dispersion has
been a problem for all designers. Large panel transducers pres-
ent unique challenge because the larger the panel, the more
directional the dispersion pattern becomes.
Wide range electrostats have long been one of the most
problematic 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 puri-
ty of the almost massless electrostatic diaphragm remained
uncompromised. After creating this technology, MartinLogan
developed the production capability to bring it out of the labo-
ratory and into the market place. You will find this proprietary
MartinLogan technology used in all of our electrostatic prod-
ucts. 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.
Generation 2 Diaphragm
The electrostatic transducer’s diaphragm employs an extreme-
ly sophisticated conductive coating applied to the polymer
surface at an atomic level using a plasma bonding process. A
proprietary compound is driven into the surface of the poly-
mer film in an oxygen free argon chamber. This process allows
extremely uniform surface resistivity characteristics, an optical-
ly transparent surface, and a nearly massless 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.
MicroPerf Stator
Sleek. Compact. MicroPerf stator technology, featured in
all XStat transducers, reveals more open playable area in
each panel, offering increased performance from even more
compact stat panels. It is significant to note that the XStat trans-
ducer supports the bandwidth and dynamics associated with
traditional electrostatic panels nearly twice its size.
Vacuum Bonding
To achieve the power, precision, and strength of the XStat
transducer, two insulated high-purity carbon steel stators along
with a proprietary plasma bonded diaphragm and ClearSpar
spacers are fused into a curved geometry with an aerospace
adhesive whose strength exceeds that of welding. Our propri-
etary Vacuum Bonding process guarantees uniform diaphragm
tensioning and extremely precise construction tolerances,
resulting in unequivocal precision, linearity and efficiency.
Folded Motion™ Tweeter
The Folded Motion Tweeter works by moving air (which
creates sound) perpendicular to the folded ridges of the dia-
phragm, similar to how an accordion works. This extremely
low mass diaphragm “squeezes” air and requires almost 90%
less excursion than the typical 1” dome tweeter, which dras-
tically minimizes distortion while providing a lightning fast
response time. The increased surface area also provides a
wide, yet controlled sound dispersion to create a realistic and
carefully etched sound stage.
