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 com-
promise in sound quality.
After extensive research, MartinLogan engineers discovered an
elegantly simple solution to achieve a smooth pattern of disper-
sion without degrading sound quality. By curving the horizontal
plane of the electrostatic transducer, a controlled horizontal dis-
persion pattern could be achieved, yet the purity of the almost
massless electrostatic diaphragm remained uncompromised.
After creating this technology, MartinLogan developed the pro-
duction capability to bring it out of the laboratory and into the
market place. You will find this proprietary MartinLogan tech-
nology used in all of our electrostatic 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.

Generation 2 Diaphragm

Montis's diaphragm employs an extremely 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 polymer film in an
oxygen free argon chamber. This process allows extremely uni-
form surface resistivity characteristics, an optically transparent
surface, and a nearly massless diaphragm. This uniform surface
resistivity controls the electrostatic charge on the diaphragm sur-
face 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 transducer in
the radical new Montis loudspeaker 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, result-
ing in unequivocal precision, linearity and efficiency.

AirFrame Technology

Ultra-rigid extruded aerospace grade aluminum alloy AirFrame
technology rigidifies and secures the XStat electrostatic panel to
the woofer cabinet while at the same time providing sonic and
electrical isolation. Advanced AirFrame technology maximizes
the electrostatic panels playable surface area and dipole disper-
sion pattern while minimizing potentially acoustically destructive
intermodulated distortion caused by spurious vibrations and res-
onance. The result? Ultimate imaging capability, low-level detail
resolution, improved efficiency and overall accuracy.
