MartinLogan Motion 50XTi Centre Speaker (Red Walnut)

For significant impact in a multi-channel audio system, MartinLogan's new Motion 50XTi center channel speaker delivers wide soundstage with pinpoint details, thanks to a Folded Motion XT tweeter, dual 6.5" aluminum cone woofers vented with a rear-firing bass port, and a proprietary Vojtko crossover network. The "XT" stands for extreme, and the Motion 50XTi offers lifelike details from the lightning-fast Folded Motion XT tweeter, open and authentic midrange performance, plus 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. MartinLogan's signature Folded Motion tweeter utilizes an extremely low mass diaphragm that "squeezes" air, thus demanding significantly less excursion than the typical 1" dome tweeter. Its folded design allows for a much larger surface area (compared to that of a regular 1" 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 advance thin-film transducer technology even further, with a 40% larger radiating surface and 80 x 30-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 superior realism and alarming specificity is aurally astounding. 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. 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). Premium Motion Series speakers feature proprietary Vojtko crossover networks using polypropylene and low-DF electrolytic capacitors, custom-wound inductors, and thermal and current protection.
