The Sound of Invisibility: Folded Motion® Tweeters

MartinLogan's signature Folded Motion Tweeter utilizes an extremely low-mass diaphragm that "squeezes" air, thus requiring significantly less excursion than the typical 1-inch dome tweeter. Its folded design allows for a much larger surface area (compared to that of a regular 1-inch dome tweeter), controlled dispersion characteristics, and vanishingly low distortion. It's a miracle of audio engineering that delivers much of the high-frequency detail, speed, and response of a large, dynamic electrostatic panel in a small space.

This thin-film transducer design packs all the accuracy and delicacy of an electrostatic panel into a small space. Folding the dramatically lightweight film into an accordion-like structure increases the surface area, giving Folded Motion tweeters eight to ten times greater surface area than typical tweeters. This ideal combination of light and large produces superior accuracy, extended frequency bandwidth, and higher output capability; all with a faster, more efficient transient response, and virtually zero distortion. In these characteristics, the Folded Motion Tweeter design can mimic the performance of a large electrostatic panel in the confines of a more traditional loudspeaker enclosure.

Woven Fiberglass Cones

All Motion CI speakers feature lightweight woven fiberglass cones specifically engineered for their application to blend seamlessly with the lightning speed of MartinLogan's signature Folded Motion Tweeter. No matter which Motion CI speaker you choose for your room, rest assured they are designed to provide a consistently high level of performance and can easily be used with other MartinLogan speakers to make creating the perfect system for your unique listening space that much easier.

The MartinLogan Sound

MartinLogan Motion CI speakers sound great in any room. Regardless of the environment, these speakers just sound better, more articulate, more detailed, and more realistic. With Controlled Dispersion and one of the most responsive tweeters in the industry, MartinLogan's in-wall and in-ceiling models can compete with and often exceed the performance of traditional cabinet speakers.
