The crossover phase aberrations that are
associated with traditional tweeter, midrange,
and woofer systems are eliminated. The result is
a dramatic improvement in imaging and staging
performance due to the minutely accurate phase
relationship of the full-range panel wave launch.
Since the beginning of audio, achieving smooth
dispersion has been a problem for all designers.
Large panel transducers present unique challenge
because the larger the panel, the more direction-
al 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 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 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.
XStat™ transducers incorporate a myriad of
technology and design innovations including
CLS™, MicroPerf, Generation 2 Diaphragms,
ClearSpars™, and Vacuum Bonding.
Sleek. Compact. MicroPerf stator technology,
featured in EM-ESL’s electrostatic transducer,
reveals more open playable area in each panel,
offering increased performance from even more
compact stat panels. It is significant to note that the
electrostatic transducer in the radical new EM-ESL
loudspeaker supports the bandwidth and dynamics
associated with traditional electrostatic panels
nearly twice its size.
To achieve the power, precision, and strength of
the electrostatic 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 proprietary Vacuum Bonding
process guarantees uniform diaphragm tensioning
and extremely precise construction tolerances,
resulting in unequivocal precision, linearity and
efficiency.
Ultra-rigid extruded aerospace grade aluminum
alloy AirFrame™ technology rigidifies and secures
the 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 dispersion pattern while
minimizing potentially acoustically destructive
intermodulated distortion caused by spurious
vibrations and resonance. The result? Ultimate
imaging capability, low-level detail resolution,
improved efficiency and overall accuracy.
