The Martin Logan Motion 15i bookshelf speakers offer the following features.

Motion 15i Bookshelf Speakers

The high-performance Motion 15i bookshelf speaker features a Folded Motion® tweeter, a 5.25-inch aluminum cone woofer

with a rear-firing bass port, and a proprietary Vojtko crossover network to deliver refined sound with stunning dynamic range

and jaw-dropping clarity. Motion 15i delivers the classic broad soundstage of the Motion Series from a newly designed

enclosure enhanced by the slightest of modifications, including the drive-stabilizing dust cap design and stiffened motor

suspension. The speaker’s cabinet sports a reinforced baffle and a fabric grille. Available in three stylish finishes: gloss black,

matte white, and red walnut.

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.

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).

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.
