MartinLogan Motion® 20i
Floor standing speaker (Matte White)

Folded Motion Tweeter: MartinLogan's signature 1.0" x 1.4" 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 also allows for a much larger surface area than compared to that of a regular 1" dome tweeter for controlled dispersion and low distortion characteristics. MartinLogan's Folded Motion tweeter is engineered to deliver much of the same high-frequency detail and speed of their large, dynamic electrostatic panel in a small space. This Folded Motion tweeter with advanced thin-film transducer technology offers a 40% larger radiating surface and 80x80 degree controlled dispersion for an increased audible bandwidth without sacrificing any detail and minimizing distortion to an unprecedented level, while also increasing efficiency and the tweeter's already lightning-fast response time. The result is a natural, realistic, and dynamic sound.

Dual Gold-Plated Binding Posts: The Motion 20i is outfitted with two sets of gold-plated binding posts allowing youto bi-amp or bi-wire the floorstanding speaker. These binding posts ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-lugs, and bare wire (up to 10AWG). The binding posts are gold-plated for excellent audio signal transfer and resistance to corrosion.

Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.

Rubber & Spike Feet: The Motion 20i floorstanding loudspeaker comes with both rubber & spike feet. The rubber feet come pre-installed on the bottom of the speaker cabinet and are ideal for hardwood, tile, laminate, and vinyl flooring. The rubber feet can be removed and the included spike feet can be screwed into the bottom of the speaker cabinet. The spike feet are designed for carpeted floors.

 

 

 

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.

 

 

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.
