MARTINLOGAN EXCLUSIVES
English
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
laboratory and into the market place. You will find this propri-
etary MartinLogan technology used in all of our electrostatic
products. It is one of the many reasons behind our reputa-
tion 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
Neolith’s diaphragm employs an extremely sophisticated con-
ductive 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 polymer film in an oxygen free
argon chamber. This process allows extremely uniform surface
resistivity characteristics, an optically 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 in the radical new Neolith loudspeaker supports the
bandwidth and dynamics associated with traditional electro-
static 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.
