They'll Redefine Your Idea of Bookshelf Speakers
The term 'bookshelf speakers' sounds so stuffy. It just doesn't do justice to the sleek and windswept look of MartinLogan's awesome Motion 4 speakers. Set 'em next to your TV, mount them on the wall, or place them on a stand. They work great and sound BIG as front channel speakers in a mid-size home theater system or as surround speakers in a larger set-up.
The Motion 4i is particularly well equipped to excel with two-channel music as well as with multi-channel entertainment sources. Its driver complement consists of a 1" x 1.4" Folded Motion™ high-frequency transducer with a 5.25" x 1.75" diaphragm plus a 4" low frequency driver with stamped steel basket, non-resonant asymmetrical chamber format, and rigid structured dust cap to reduce cone break-up modes.
The Motion i Series
Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 2i, 4i, 6i, and 8i feature exquisite Folded Motion tweeters and powerful bass technology in compact and affordable packages. Key to performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (much larger than a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jaw-dropping clarity certain to inspire envy in audiophiles and non-audiophiles alike.
Precision Vojtko™ crossover topology features custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low DF electrolytic capacitors for a seamless sonic presentation. Flexible installation options allow table top or on-wall installation of all four speakers. Motion 2i and 4i bookshelf speakers can also mount upside down to facilitate placement high on a wall. Motion 6i and 8i can mount horizontally or vertically around a wall-mounted flat screen television.
Engineering Genius
What makes the Motion i Series sound so amazing? MartinLogan's dedicated in-house engineering team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price.
Folded Motion™ Tweeter
MartinLogan's exclusive and highly innovative Folded Motion™ Tweeter helps gives Motion i speakers their fantastically realistic highs. Lightning fast transient response, combined with a large surface area creates clear, highly dynamic, and precise sound.
The Folded Motion™ Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90 percent less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lighting fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
Vojtko™ Crossover
Contributing to the superb performance is the legendary Vojtko™ crossover. It is carefully hand-built using only the finest polyester film and low DF electrolytic capacitors, custom air-core coils, and low DCR steel laminate inductor for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.
Curve Appeal
Complementing Motion's sonic accuracy is elegant yet understated styling. Flawless high-gloss, piano black finishes and subtle curves, along with MartinLogan's signature perforated grille, gives Motion i Series speakers an elegant and timeless look. Tower models feature a real-wood veneer finish and a stylish aesthetic certain to blend with any decor.
Hook-ups, Simplified
Convenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. So simple, you'll actually enjoy hooking up these speakers.
