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.

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.

Each cone is reinforced by a Nomex backer, for additional damping that prevents ringing and reduces breakup modes in these extremely rigid cones. The drivers feature powerful, efficient magnet structures, enabling massive excursion and huge sound output, while preserving deep bass details, even at sustained, lifelike volume levels.

Monument 7XW features passive radiators constructed from the same high-strength, low mass material as the woofers—unidirectional carbon fiber multi-section cones with Nomex® backers. These passive radiators ensure shockingly powerful, dynamic, and distortion-free bass from a small, unobtrusive, sealed enclosure.

Driver Engineering Details

To deliver accuracy in the critical midrange, mid-frequency drivers feature a specially engineered “stiff” suspension. Stiffening the suspension (the spider and surround) raises the driver’s resonant frequency and optimizes its performance to achieve a natural roll-off and inherently operate within an ideal range for a mid-frequency reproduction (as opposed to a comparably sized woofer).

Each cone includes a concave dust cap that adds additional strength and rigidity while further reducing break up modes. An inverted surround design maximizes clearance behind the grille cover to enhance driver excursion, clarity, and linearity.

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. It offers extraordinary material consistency that naturally minimizes deleterious resonances and vibrations.

Masterpiece CI back boxes fit into standard stud walls. They provide controlled and predictable airspace (volume) within which the specially engineered drivers can perform at their best. The sealed box removes variables, like wall cavity size and construction quality, from the acoustic equation, guaranteeing a consistent, accurate performance, regardless of installation specs.

Also, the hermetically sealed design keeps sound from leaking through walls.

By controlling the sealed space volume and damping characteristics, and maintaining complete control over driver performance, crossover design, and cabinet construction, Masterpiece CI in-wall and in-ceiling speakers achieve an emotionally engaging experience on par with the performance of the world's most exceptional floorstanding speakers. (Our own.)

Die-cast Aluminum Mounting-Lock System

A simple, yet robust die-cast aluminum mounting-lock system maximizes strength while allowing quick, trouble-free installation. Pocketed screw holes help hold the drill steady, making installation a snap. When not in use, mounting locks are secured within a self-contained housing. When moved into place, they couple the chassis firmly to the ceiling or wall, increasing the rigidity of surfaces. If ever removed, the locks retract and latch back in their housings. Each speaker includes a full-size installation template featuring quick-reference instructions, and die-cut guides for marking the cutout hole.

Spring-Loaded Binding Posts

With easy pre-installation access, our spring-loaded binding posts feature a large 4.5mm wire access hole and connect via banana plug, pin, or 10AWG bare wire.

Proprietary Vojtko™ Crossover Networks

Vojtko Crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko.

His unique approach to crossover design is just as crucial to MartinLogan's Truth in Sound as are our innovative electrostatic and Folded Motion thin-film driver technologies. A Vojtko Crossover isn't just a set of design requirements; it's a philosophy.

Vojtko Crossovers are hand-built from the highest quality components and avoid overly complex topologies. This crossover has a straightforward objective: breathtaking realism.

Hand-Selected Components

In designing each crossover topology, we take the drivers themselves into consideration. Carefully selected drivers, engineered for specific performance characteristics, are kept within their optimal frequency range by the custom Vojtko Crossover.

Each crossover is handcrafted using exceptional polypropylene and polyester capacitors, custom wound and large steel laminate low-DCR inductors, and double thick PCBs. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source. It's a recipe for vanishingly low distortion and seamless driver integration.

The most critical aspect of a Vojtko Crossover design is the final voicing, always conducted in a real-world environment. This uniquely pragmatic approach guarantees that even the most amazing MartinLogan loudspeakers, like the massive Statement 40XW, deliver Truth in Sound in any room, including yours.

Pre-Installation Brackets (sold separately)

Pre-installation brackets are available for every model in the Masterpiece CI Series, except for the Statement 40XW, which requires unique considerations for installation.
