Folded Motion® XT Obsidian Tweeters
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.
