Push-Pull Operation = Ideal Linearity
Linearity is another factor contributing to a loudspeaker's
ability to achieve ultimate clarity, detail and resolution. By
positioning neodymium magnet arrays in a push-pull con-
figuration, MartinLogan ATF transducer technology maintains
uniform diaphragm control, regardless of position as it
traverses the entire audio signal. The push-pull concept is
a major contributor to the linearity and sonic superiority of
ATF transducers.
Direct Full-Surface Drive
Provides Outstanding Clarity
Unlike traditional voice coil driven systems, ATF diaphragms
are directly and uniformly driven throughout their entire
surface. This full-surface drive system results in ultra-fast
transient response with no cone break up and the ability
to accurately reproduce sound with great delicacy, nuance
and clarity.
