Folded Motion

XT Obsidian Tweeters.
MartinLogan’s signature Folded Motion
tweeter is a miracle of audio engineering. Its
folded thin-film diaphragm gives it a much
larger surface area than traditional dome
tweeters of the same size. This “squeezing”
design requires significantly less excursion
than a dome tweeter, too, revealing controlled
dispersion characteristics and vanishingly low
distortion. These tiny tweeters mimic the high-
frequency detail and response speed of a
large electrostatic panel in a small space.
Masterpiece CI Series steps up the game
with the Folded Motion XT Obsidian
tweeters, which advance thin-film
transducer technology even further.
The Folded Motion XT design features a 40%
larger radiating surface and 80 x 30-degree
controlled dispersion. This innovation increases
audible bandwidth without sacrificing details
and minimizes distortion to an unprecedented
level, even while increasing the efficiency of the
tweeter’s already lightning-fast response time.
The result is superior realism and
alarming specificity. Folded Motion XT
takes thin-film transducers to the next
level—it’s aurally astonishing.
