Masterpiece CI Presents Flagship Performance from In-Wall and In-Ceiling Speakers
From extreme home theater to transcendent 2-channel listening, Masterpiece CI achieves the pinnacle of discreet in-wall and in-ceiling loudspeaker design: state-of-the-art Truth in Sound that takes up no floor space. Featuring lightning-fast, low-distortion, Folded Motion XT Obsidian tweeters, handcrafted Vojtko crossover networks, and unidirectional carbon fiber multi-section cone drivers with Nomex® backers, each model of the Masterpiece CI Series delivers astonishing realism. This is a loudspeaker that is a tribute to the acoustic achievements of MartinLogan's original iconic masterpiece, our flagship floorstanding electrostatic speakers.

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.
