Masterpiece CI Series High-Performance In-Wall and In-Ceiling Loudspeakers Truth in Sound
State-of-the-art Truth in Sound: Masterpiece™ CI Series offers the biggest, boldest, and most lifelike performance possible. We consider something a masterpiece when skill and artistry shape the familiar in unexpected ways, revealing an essential truth. For MartinLogan, the essential truth is astonishing and unprecedented audio realism.
Statement 40XW Tech If your performance benchmark is MartinLogan’s most ambitious floorstanding hybrid electrostatic loudspeakers, it’s going to be quite a challenge to achieve that level of accuracy and impact in an in-wall speaker. Challenge accepted. The Statement 40XW is a triumph of audio engineering. Its performance (and sheer size) rivals the very best of our electrostatic models, with full-on speed and high-frequency accuracy, incredibly detailed midrange, and lifelike deep bass impact.
Dispersion of Statement 40XW of the Folded Motion XT tweeters, and the sheer 52-inch-tall cliff of vertical tweeters, minimizes side-wall, floor, and ceiling reflections whose short arrival times tend to interfere with our perception of “direct” sound. The result is a broad, enveloping soundstage, with an accurate, lifelike rendering of the most subtle imaging details, even in an ample listening space. Statement 40XW—Surprisingly Discreet Installation.
Dispersion of Icon 3XW, Tribute 5XW, and Monument 7XW Masterpiece CI Tech 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.

Powerful Mid-Frequency and Bass Drivers with Unidirectional Carbon Fiber Multi-Section Cones with Nomex® Backers. Masterpiece CI loudspeakers feature cones custom-built using unidirectional carbon fiber, a material that is twice as strong as steel but with a sixth of the density, for exceptional rigidity without excessive weight. They are designed in multiple sections to take full advantage of the benefits of this material.

“The artist must be a philosopher…an artistic genius should have no other guide except the torch of reason.” – Jacques-Louis David Proprietary Vojtko™ Crossover Networks. Vojtko Crossovers are named after MartinLogan’s chief audio technologist, Joe Vojtko. engineered for specific performance characteristics, are kept within their optimal frequency range by the custom Vojtko Crossover.
• FOUR DRIVERS • ONE TWEETER: FOLDED MOTION ® XT OBSIDIAN • TWO MID: 3.
Phenolic Baffle and Sealed Back Box Enclosure. One key to replicating the performance of traditional loudspeakers with hidden, built-in speakers is the use of sealed, controlled-volume, back boxes. Statement 40XW, Monument 7XW, Tribute 5XW, and Icon 3XW, feature baffles of incredibly dense phenolic resin polymer fronted by an aluminum faceplate. This phenolic resin polymer is the same material we use in the Neolith’s massive, acoustically-inert cabinet.

The Birth of a Masterpiece Picasso’s youthful realistic style soon gave way to the groundbreaking cubist images that made him famous. The more traditional style of the young Van Gogh matured into the bold, colorful impressionism we recognize today. This same artistic trajectory was traveled by Gayle Martin Sanders and Ron Logan Sutherland, as they grappled with improving the “finicky” characteristics of classic electrostatic loudspeaker designs. Early electrostatics were prized for their purity and clarity.
Folded Motion Drivers at Work. How do you transform the breathtaking detail and lightning-fast accuracy of the world’s best electrostatic transducers into more traditional loudspeaker designs? That’s the (very) basic idea behind MartinLogan’s exclusive Folded Motion tweeter design—a uniquely engineered thin-film diaphragm that fits into a traditional speaker cabinet. This extremely low mass diaphragm “squeezes” air, demanding significantly less excursion than a typical dome tweeter.
