Details: Motion 20i Floorstanding Speakers
A compact floorstanding loudspeaker with a performance that is anything but small, the new Motion 20i features a Folded Motion tweeter, dual 5.5–inch aluminum cone woofers with a rear–firing bass port, and a proprietary Vojtko crossover network. Motion 20i delivers the classic broad soundstage of the Motion Series from a newly designed enclosure enhanced by the slightest of modifications, including the drive–stabilizing dust cap design, stiffened motor suspension, and low–mounted woofers.
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 XT 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, 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.
Powerful Aluminum Cone Mid–Frequency and Bass Drivers
Custom built, low–distortion drivers pair high–power magnet structures with aluminum cone diaphragms to deliver massive excursion and sound output, preserve minute bass details, and maximize power handling capability, all without a hint of distortion. A unique concave dust cap design reinforces the strength and rigidity of the cone while reducing break up modes. The use of aluminum for cones maximizes rigidity and strength of the drivers without adding excessive weight.
