Description
Audiophile performance without an audiophile price. Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, MartinLogan Motion 8i features a Folded Motion tweeter, dual 4-inch paper cone woofers, and a proprietary Vojtko crossover network in a compact and affordable package. Flexible installation options allow table top or on-wall installation. Motion 8i mounts horizontally or vertically, ideal for placement around a wall-mounted flat screen television. Motion 8i also features recessed push-style binding posts that accommodate banana jacks. Available in gloss black.
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.
Proprietary Vojtko ™ Crossover Networks
Compact Motion Series speakers feature proprietary Vojtko crossover networks using custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low-DF electrolytic capacitors for a seamless sonic presentation.
Modern Curves and Luxurious Finish
After refining the perfecting the acoustic details, MartinLogan designers focused on elegant yet understated styling that complements flat-panel televisions and other high-end components. To achieve this, we gave compact Motion bookshelf and center channel speakers a flawless gloss black finish and compact, slender enclosures. Subtle curves, along with MartinLogan’s signature perforated grille, add to the elegant and timeless look.
Easy Hookup
Convenient, high-quality, push-style binding posts are recessed into the speaker’s cabinet along with curved guides that allow wires to slide into place effortlessly. These binding posts are also designed to facilitate the use of banana plug connectors.
