Martin Logan Motion 50XTi Centre Channel Speaker

For significant impact in a multi-channel audio system, the new Martin Logan Motion 50XTi delivers wide soundstage with pinpoint details, thanks to a Folded Motion® XT tweeter, dual 6.5-inch aluminium cone woofers vented with a rear-firing bass port, and a proprietary Vojtko crossover network. XT stands for extreme: lifelike details from the lightning-fast Folded Motion XT tweeter, open and authentic midrange performance, coupled with deep, musical bass response. These classic performance technologies have been enhanced by the slightest of modifications, including the drive-stabilizing dust cap design and stiffened motor suspension. The speaker’s enclosure sports increased internal bracing, a reinforced baffle, and a fabric grille.

Engineering, Without Compromises

What makes the 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 (and most times trounces) traditional loudspeakers of similar size and price. Our ‘no compromise’ philosophy gives Motion Series a unique sound you won’t find anywhere else.


Sound Inspired by Electrostatic Speakers

The success of the 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 the Motion Series.

Folded Motion® Tweeters

MartinLogan’s signature Folded Motion tweeter utilizes an extremely low mass diaphragm that “squeezes” air, thus demanding significantly less excursion than the typical 1-inch dome tweeter. Its folded design allows for a much larger surface area (compared to that of a regular 1-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.

Equipped with dual Folded Motion XT tweeters, the Martin Logan Motion 50XTi reproduces high frequencies with unparalleled precision and detail, creating a wide and immersive soundstage. The 6.5-inch aluminium cone woofers deliver tight and impactful bass response, adding depth and richness to your music and movies.


Powerful Aluminium Cone Mid-Frequency and Bass Drivers

Custom built, low-distortion drivers pair high-power magnet structures with aluminium 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 aluminium for cones maximizes rigidity and strength of the drivers without adding excessive weight. This, along with the exceptional damping properties of aluminium, ensures the smooth, non-resonant response necessary for seamless blending with high-resolution Folded Motion tweeters. An added benefit of aluminium 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).

Modern Design Featuring Luxurious Finishes

Discreetly hidden behind fabric wrapped magnetic grilles, Folded Motion and aluminium 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. The Martin Logan Motion 50XTi and 60XTi feature additional internal bracing to further reduce cabinet resonance.
