MartinLogan’s New Motion Series Unveiled
MartinLogan will make available in October seven new Motion Series music/home cinema loudspeakers: three floorstanding, two bookshelf and two center-channel models.
The company says that the new line of multi-application speakers uses proven performance technologies found in previous generations with an updated design, and is inspired by the performance of MartinLogan’s legendary ultra-high-end electrostatic loudspeakers, featuring the Folded Motion tweeter, hand-built crossovers and special cabinet construction techniques.
The company said that the desire to transmute that level of performance into a more traditional speaker at a more affordable price drove the initial design imperatives that created the Motion Series.
Key features include: Folded Motion® and Folded Motion® XT tweeters; aluminum cone midrange drivers and woofers with concave dust caps that reinforce the strength and rigidity of the cone; proprietary Vojtko™ crossover networks featuring custom air core coil and low DCR steel laminate inductors; polypropylene film capacitors in series and low DF electrolytic capacitors in parallel; and custom five-way tool-less binding posts.
MartinLogan’s Folded Motion tweeter uses a low-mass diaphragm that “squeezes” air, thus demanding less excursion than the typical 1-inch dome tweeter, the company says. Its folded design allows for a much larger surface area compared to that of a regular 1-inch dome tweeter, controlled dispersion characteristics, and low distortion – engineering that the company says delivers the high-frequency detail and speed of a large, dynamic electrostatic panel in a small space.
Models include the floorstanding Motion 60XTi ($1,599.99 each); Motion 40i ($1,099.99 each); and compact Motion 20i ($849.99 each). Bookshelf speakers are the Motion 35XTi ($649.99 each) and the Motion 15i ($399.99 each). Center-channel models are the Motion 50XTi ($999.99 each) and the Motion 30i ($749.99 each).
The Motion Series floorstanding model 60XTi, center-channel model 50XTi and bookshelf model 35XTi feature the Folded Motion XT tweeters, with a 40 percent 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 response time.
The series’ floorstanding Motion models use 2.5-way designs that feature woofers positioned low in the cabinet and close to the floor, to minimize floor bounce – a phenomenon where sound reflected off the floor, from drivers positioned high on a cabinet and those aimed directly at the listener, interfere with each other.
The speakers’ proprietary Vojtko™ crossover networks use polypropylene and low-DF electrolytic capacitors, custom-wound inductors, and thermal and current protection.
These new Motion Series speakers will be available in three 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.
