Statement 40XW: MartinLogan Performance, Built In
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. And yet it takes up absolutely no space in your room and vanishes into any decor.
It's an incredible sixteen tweeters, and sixteen mid-range drivers, and eight woofers, arrayed in a line-source design and built directly into your wall, delivering awe-inspiring levels of full-spectrum dynamic output even in the largest listening areas.
The keys to this performance are superior components and innovative design. The multi-driver design allows each driver and tweeter to operate with extreme efficiency. This combination of high-resolution drivers, each working to offset the demands on the others, results in a highly accurate and distortion-free performance, even during the most demanding sonic passages, and even at realistic volume levels. The large line-source design also ensures the same sonic impact over a large area of listening positions. There's no drop-off, as can be the case with smaller, point-source designs.
With each channel featuring a mind-boggling forty drivers, you simply have to hear the Statement 40XW to believe it.
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.
Surprisingly Discreet Installation
Whether you are designing a new listening room from the ground up or retrofitting a room back to the studs, it's the perfect time to incorporate built-in audio. And if you're planning a larger than average space, it's worth considering a massive line-source loudspeaker that both vanishes into your decor, and puts even the farthest seat in the sweet spot.
The Statement 40XW incorporates a reinforced, sealed, acoustically-inert back box enclosure that isolates and decouples the drivers from the wall surface.
This sealed box enclosure, with its uniform volume and material, eliminates in-wall variables from the acoustic equation, guaranteeing a consistent, accurate performance in any installation. The sealed design also effectively eliminates audio leak-through into adjoining rooms.
It fits comfortably between studs and works with both 1/2- or 5/8-inch wallboard.
The low profile, paintable, micro-perforated grille presents a clean, near-invisible aesthetic. One of the world's most incredible audio performances, from practically invisible loudspeakers!
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.
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.
