For significant impact in a multi-channel audio system, the new Motion 50XTi delivers wide soundstage with pinpoint details, thanks to a Folded Motion® XT tweeter, dual 6.5-inch aluminum 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. 


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® 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 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. 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.
