Convincing Three-Dimensional Sound

Martin Logan’s Motion FX surround speaker offers enveloping audio performance that is ideal for large, medium, and small rooms. Inspired by MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion FX features dual Folded Motion tweeters in a wide dispersion configuration. The speaker also provides powerful bass and folded reflex port technology in a compact, affordable package.

The key to Motion FX’s performance is the lightning fast response of the tweeter’s lightweight diaphragm combined with a surface area that’s eight-times larger than that of a typical one-inch dome tweeter. The 5.25″ paper cone woofer is doped for stability and damping and includes a rigid dust cap. The result of all this technology is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.

The Motion FX excels in either bookshelf or on-wall installations. The design lends itself easily to on-wall installation in a corner, flat on a wall, or angled on a wall.

The MartinLogan Motion Series

Inspired by MartinLogan’s ultra-high-end electrostatic loudspeakers, the Motion Series was created to provide stunning sound for your ultimate-performance home theater or stereo. MartinLogan’s dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends the company’s exquisite Folded Motion™ transducers with powerful, compact bass technology. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.

Engineering Genius

What makes the Motion 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 speakers their fantastically realistic highs. Lightning fast transient response, combined with a large surface area (eight-times that of a typical 1″ dome tweeter) 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 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.
