Expansive Sound and Sophisticated Aesthetics
MartinLogan's elegant Motion 20 tower speaker features the company's advanced resolution Folded Motion™ tweeter and two 5.5" aluminum bass cones. Detailed high and midrange frequencies, a tight low end, and expansive soundstage are hallmarks of the Motion 20 design.
Two Motion 20s will deliver spectacular stereo performance. For home theater, the Motion 20 also excels, and it's voice-matched to MartinLogan's Motion 30 center channel speaker and Motion FX surround speakers. Bass aficionados can add a high-performance MartinLogan subwoofer.
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.
The Motion 20's two 5.5" aluminum cone woofers use a non-resonant asymmetrical chamber format with cast polymer basket. A rigid structured dust cap reduces cone break-up. The rear-firing bass port adds extra punch in the low frequencies.
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.
MiniETC™ (Energy Transfer Coupler) Spikes
Included with your MartinLogan are sturdy, 1/4-20 MiniETC™ spikes, which can be used in place of the standard feet to enhance stability on thick carpets or to create tighter coupling between speaker and floor.
Curve Appeal
Complementing Motion's sonic accuracy is elegant yet understated styling. The flawless high-gloss, piano black finish and MartinLogan's signature perforated grille, gives Motion Series speakers an elegant and timeless look. |
