Forty drivers. Seven feet tall with a 52-inch stack of thin-film tweeters. It's the flagship of the Masterpiece CI Series. The Statement 40XW is an enormous, self-contained in-wall loudspeaker system using a super-efficient line-source design to deliver a massive dynamic attack in even the largest listening areas. And it's virtually invisible, taking up no floor space at all. Statement 40XW is an audio experience like no other—only from MartinLogan.

• Sixteen lightning-fast Folded Motion XT Obsidian tweeters.
• Sixteen 3.5-inch unidirectional carbon fiber multi-section cone midrange drivers with Nomex backers.
• Eight timbre-matched 6.5-inch unidirectional carbon fiber multi-section cone woofers with Nomex backers.
• Proprietary Vojtko crossover networks seamlessly blend drivers across the full spectrum.
• Phenolic baffle and acoustically-inert sealed back box enclosure that easily installs.
• Low profile, paintable, micro-perf grilles vanish into any decor.

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.

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.

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.
