Martin Logan Motion 20 Black Floorstanding Speakers, Model MO20GBK
The Motion 20 is a breathtaking visual statement regardless of its compact dimensions. Dual 5-1/2” aluminum-cone woofers are paired with a rear-firing bass port for extra punch in the low frequencies. With the addition of our exquisite Folded Motion™ tweeter it’s a design that delivers solid low-frequency reinforcement, superb sound dispersion and precise, highly dynamic high frequencies. Sitting on top included MiniETC™ Spikes, this combination creates audible acoustic alchemy across the frequency spectrum and offers an extremely expansive soundstage, richly detailed highs, and an open & revealing midrange.
Features:
- This is one sweet tweeter
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% less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
- 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. Although our engineers won't reveal exactly how they make the sausage, here are a few technologies that help give MartinLogan Motion Series such a unique sound.
- A Versatile Performer
Each model feature dual sets of custom 5-way binding posts for bi-wire/bi-amp capabilities and powerful rear-firing bass port. Stability is enhanced to create tighter coupling between speaker and floor with the included spikes.
