14 ATF (Advanced Thin Film)
ATF (ADVANCED THIN FILM)
ATF Operation
The MartinLogan ATF transducer (based on RADIA planar
technology) consists of a micro-thin, low-mass Kaladex
diaphragm with an ultra-light, etched conductive alumi-
num surface suspended between two high field strength
neodymium super magnet arrays (see figure 27). When an
electrical current (music signal) passes through the etched
aluminum on the diaphragm's surface it is simultaneously
pulled towards one of the neodymium arrays and pushed
away from the opposing array. When the direction of current
is reversed the diaphragm is simultaneously pushed and
pulled in the opposite direction, thus producing sound.
Extremely Low-Mass Diaphragm
—Blazing Speed and Inner Detail
Low-mass diaphragms are crucial to a loudspeaker's ability
to accurately reproduce sound. As the mass of a transducer's
diaphragm decreases, its ability to resolve detail increases.
With extremely low-mass characteristics, the ATF transducer
tracks the audio signal with almost perfect accuracy.
MartinLogan ATF diaphragms are constructed of extremely
low mass Dupont Kaladex® PEN (polyethylene naphthal-
ate) —a material chemically similar to the low-mass PET
(polyethylene terathylate) film used in MartinLogan's gener-
ation 2 electrostatic transducers, yet capable of handling
the high thermal requirements required for stable magnetic
thin film operation.
High Field Strength
—Superb Control and Efficiency
With a field strength almost 2000% more powerful than
traditional systems, Neodymium iron boron (NIB) rare-earth
super magnets are one of the world's strongest commer-
cially available magnetic materials. This incredible field
strength proves ideal for maintaining perfect control over
the low-mass Kaladex diaphragm. Super-low distortion
levels, high-resolution, and crystal-clear transparency are
just a few of the benefits resulting from this superb combi-
nation of low-mass diaphragm and high field strength.
