MartinLogan Motion 50XTi Features Wide Sound Dispersion, XT Folded Motion Tweeter, 6.5-Inch Woofers

The most tricked-out home-theater receiver in the world won't be nearly as satisfying as it could be if your speakers can't deliver everything the very latest surround technologies have to offer. Engineered to unveil the incredible detail and life-like imaging embedded in your favorite movies, and given updated enclosures with reinforced baffles that virtually eliminate cabinet resonances, Martin Logan's Motion 50XTi center-channel speaker comes equipped with the company's widely acclaimed XT Folded Motion tweeter, which moves more rapidly and effectively than a typical dome or cone tweeter. Combined with low distortion, its wide sound dispersion delivers the finest nuances of critical dialogue and important spotlight action to every person sitting in your home-theater space – something lesser center-channel designs cannot do. And with an amazing 94dB efficiency rating, Motion 50XTi can be driven comfortably by everything from a 30Wpc receiver to a 300Wpc audiophile-grade amplifier.

Further ensuring the wide dynamics of center-stage thrills arrive at your listening position with full force, Motion 50XTi's two 6.5-inch high-excursion woofers work in conjunction with two low-turbulence, rear-firing bass ports. The special design also incorporates a custom air-core coil and low DCR steel laminate inductors as well as polyester film capacitors in series and low DF electrolytic capacitors in parallel. And while Motion 50XTi only stands 7.6 inches tall with a 22.8 x 12.8-inch (WD) footprint, guests will be surprised by its ability to offer chest-thumping sound effects while also rendering instruments and effects with effortless realism.

If you've been thinking that a limited budget would prevent you from experiencing world-class sound, it's time to try out Motion 50XTi – backed by MartinLogan's five-year warranty and Music Direct's 100% Satisfaction Guarantee.

"Because dialogue clarity is so critical when watching a movie, there is a temptation to design a center channel that emphasizes certain portions of the audio spectrum that enhance dialogue. Not so with the 50XTi, which uses the exact same drivers as the other speakers, so the tonal balance remains smooth across the front stage."
– Michael Trei, Sound & Vision, Top Pick review

Engineering without Compromises

What makes Motion Series sound so amazing? MartinLogan's dedicated in-house engineering and design team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering and time-honored cabinet construction techniques. The result is an emotionally engaging sound that rivals traditional loudspeakers of similar size and price.

Sound Inspired by Electrostatic Speakers
The success of Motion Series is directly attributed to its close relation to MartinLogan's legendary ultra-high-end electrostatic loudspeakers. The desire to transmute that level of performance into a more traditional loudspeaker at a more affordable price drove the initial design imperatives that created Motion Series.

Folded Motion XT Tweeters
MartinLogan's signature Folded Motion tweeter utilizes an extremely low mass diaphragm that "squeezes" air, thus demanding significantly less excursion than the typical one-inch dome tweeter. Its folded design allows for a much larger surface area (compared to that of a regular one-inch dome tweeter), controlled dispersion characteristics, and vanishingly low distortion. It's a miracle of audio engineering that's able to deliver much of the high-frequency detail and speed of a large, dynamic electrostatic panel in a small space. Folded Motion XT tweeters, advanced thin-film transducer technology even further, with a 40% larger radiating surface and 80x30-degree controlled dispersion. This tweak increases audible bandwidth without sacrificing details and minimizes distortion to an unprecedented level while increasing efficiency and the tweeter's already lightning-fast response time. The result – superior realism and alarming specificity is aurally astounding, and only by MartinLogan.

Powerful Aluminum Cone Mid-Frequency and Bass Drivers
Custom built, low-distortion drivers pair high-power magnet structures with aluminum cone diaphragms to deliver massive excursion and sound output, preserve minute bass details, and maximize power handling capability, all without a hint of distortion. A unique concave dust cap design reinforces the strength and rigidity of the cone while reducing break up modes. The use of aluminum for cones maximizes rigidity and strength of the drivers without adding excessive weight. This, along with the exceptional damping properties of aluminum, ensures the smooth, non-resonant response necessary for seamless blending with high-resolution Folded Motion tweeters. An added benefit of aluminum is its outstanding thermal conduction capability which allows cones to serve as efficient heat sinks for voice coils. 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).

Proprietary Vojtko Crossover Networks
Premium Motion Series speakers feature proprietary Vojtko crossover networks using polypropylene and low-DF electrolytic capacitors, custom-wound inductors, and thermal and current protection. Vojtko crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko. His unique approach to crossover design is as big of a part of the MartinLogan Sound as are electrostatic and Folded Motion thin-film driver technologies. A Vojtko crossover isn't so much a set of design requirements as it is a philosophy. Vojtko crossovers are designed in such a way that all drivers are kept within their optimal frequency range and balanced with one another. The drivers themselves are as much a part of a Vojtko crossover as are capacitors and resistors. Before the design of any crossover begins, drivers are carefully selected or designed to operate within a very intentional frequency range and with precise and predictable performance parameters. Vojtko crossovers are always built from high-quality parts, and care is taken to avoid overly complex topologies – a straightforward objective due to the careful selection of woofers and tweeters. The final (and most critical) aspect of a Vojtko crossover is that final voicing is conducted in a space that is indicative of a real-world environment. This pragmatic approach allows MartinLogan speakers to sound their best in real-world rooms.

Modern Design Featuring Luxurious Finishes
Discreetly hidden behind fabric wrapped magnetic grilles, Folded Motion and aluminum cone drivers are held securely in place beneath matte black trim that masks tweeter and woofer mounting hardware for a clean, modern aesthetic. Solid cabinets, designed to eliminate fidelity robbing vibrations, are constructed from 18mm (0.7-inch) MDF with 31mm (1.2-inch) thick front baffles. MartinLogan's premier Motion Series speakers are available in three luxurious finishes and matching metallic trim – gloss black with black grilles and gunmetal grey trim, matte white with silver grilles and silver trim, and red walnut with black grilles and champagne colored trim.

Custom Five-Way Tool-Less Binding Posts
Premium gold-plated five-way tool-less binding posts assure a stable connection while accommodating a wide range of connections. Two sets of binding posts accommodate bi-wire connections to increase signal carrying conductors and allow each portion of the crossover to be directly coupled to the amplifier.
