XT Folded Motion Ribbon Tweeter and Two Eight-Inch Woofers Lead to Intoxicating Sound: MartinLogan Motion 60XTi Tower Loudspeakers Play with Remarkable Depth and Naturalism

Offering seductively smooth, clear detail as well deep, musical bass, the MartinLogan Motion 60XTi tower loudspeaker plays with an intoxicating sound and wowing depth that attest to its high-value worth. One of the secrets behind its success pertains to its unique XT Folded Motion ribbon tweeter. Boasting a 40 percent larger radiating surface than other any other MartinLogan Motion speaker, 60XTi's incredibly wide dispersion projects multi-layered, distortion-free high-frequency information far beyond the boundaries of conventional speakers. Able to move more rapidly and effectively than a typical dome or cone tweeter, thereby playing with more speed and accuracy, it also makes room-reflection artifacts a concern of the past.

In addition to impressive tweeter performance and new enclosures with reinforced baffles that virtually eliminate cabinet resonances, Motion 60XTi arrives equipped with a 6.5-inch aluminum-cone woofer uniquely positioned in a non-resonant asymmetrical chamber and housed in a cast polymer basket. Its compelling midrange and stalwart accuracy will keep your toes tapping late into the wee hours. Two identically designed eight-inch woofers with rear-firing bass ports produce chest-thumping low frequencies, while the rigidly structured dust caps drastically reduce the cone breakup often heard in lesser designs.

Also unlike from many speakers in its crowded price category, Motion 60XTi doesn't require careful amplifier matching to deliver sweeping dynamics and chest-thumping bass response. A custom air-core coil and low DCR steel laminate inductors – as well as polyester film capacitors arranged in series and low DF electrolytic capacitors situated in parallel – are modeled on the same cutting-edge tech found in MartinLogan's more expensive flagships.

Visually, Motion 60XTi features a luxurious, high-gloss piano black finish sure to turn heads. At 48 inches tall with a 11.4 x 14.4-inch (WD) footprint, it moves plenty of air but remains compact enough to fit in space-challenged environments. Five-way bi-wire tool-less binding posts and removable spikes add to its user-friendly versatility. MartinLogan's iron-clad five-year warranty and our 100% Music Direct Satisfaction Guarantee ensure Motion 60XTi has everything else you need.

"The 60XTi's sense of focus and clarity through the mid- and high-frequency ranges was exceptional, with no sense of strain or compression even when the volume was turned up pretty high."
– Michael Trei, Sound & Vision, Top Pick review

Engineering without Compromise
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  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 advance 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 while increasing efficiency and the tweeter's already lightning-fast response time.

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. 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).

Low-Mounted Woofers Minimize Floor Bounce
Floorstanding Motion models utilize 2.5-way designs that feature woofers positioned low in the cabinet and close to the floor. This deliberate design addresses a phenomenon known as floor bounce where sound reflected off the floor (from drivers positioned high on a cabinet), and those aimed directly at the listener interfere with each other. Without addressing these issues, listeners would experience bloated bass and massive increases and decreases in sound levels throughout critical midrange frequencies. Through careful crossover design and driver positioning, floorstanding Motion speakers deliver a flat, balanced response through the bass and midrange regions. Such considerations are crucial when seeking to achieve accurate reproduction of vocals and instruments such as kick drums.

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. Motion 60XTi and 50XTi feature additional internal bracing to further reduce cabinet resonance. 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 5-Way Tool-Less Binding Posts
Premium gold-plated 5-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.
