The Benefits of Line Source Configuration
The line-source design, a tall vertical array of identical sets of drivers, shares significant characteristics with hybrid electrostatic loudspeakers—something we know a little about.
Like electrostatic speakers, line-source arrays restrict vertical dispersion, eliminating the majority of a room’s performance-destroying sound reflections.
In the Statement 40XW, the combination of the natural 80-degree horizontal dispersion pattern 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.
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.
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.
Driver Engineering Details
Masterpiece CI features innovation upon innovation.
To deliver more accuracy in the critical midrange, the mid-frequency drivers have had their suspensions (spider and surround) “stiffened.” Stiffening the suspension raises the driver’s resonant frequency and optimizes its performance to achieve a more natural roll-off, inherently keeping it in an ideal range for mid-frequency reproduction.
Each cone includes a concave dust cap that adds additional strength and rigidity, while further reducing breakup modes.
Masterpiece CI mid-range and bass sections perfectly blend with the extreme accuracy of the high resolution Folded Motion XT tweeters, for a bold, seamless, distortion-free line-source performance throughout large listening areas.
An inverted surround design maximizes clearance behind the grille, helping 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.

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.
