The MartinLogan Sound

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

No matter which Motion XT CI speaker you choose for your room, they're designed to provide a consistently high level of performance and are easily compatible with other ML speakers for your unique listening space.

Elevated ML Performance

For true next level performance over the MC8 (its Motion CI counterpart), the XTC8 features ML's largest and highest performing FMT XT and a woven Kevlar woofer. These features make a noticeable improvement to the sound but also help to reduce unwanted room acoustic artifacts. With a more controlled 80° x 30° dispersion, the FMT XT is a powerful tool that delivers unheard levels of realism from a CI speaker in even the most acoustically challenging rooms. The XTC8 is a great choice for a high performance whole house music system, or for premium home theater as it allows you to control where sound is placed in a room and provides a better experience.

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" 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 delivers much of the high-frequency detail, speed and response of a large, dynamic electrostatic panel in a small space. Folded Motion XT tweeters advance thin-film transducer technology even further with a 40% larger radiating surface and 80x30-degree controlled dispersion. This upgrade increases audible bandwidth without sacrificing detail and reduces distortion to an incredibly low level while increasing efficiency and the tweeter's already lightning-fast response time. The result is superior realism and alarming specificity that is aurally astounding, and only by MartinLogan.

Woven Kevlar Cones

All Motion XT CI speakers feature very lightweight woven Kevlar cones specifically engineered to keep pace with the lightning speed of our highest performance XT FMT. While these high-performance drivers offer both increased rigidity and lightness, we took an extra step by adding a special Nomex layer on the back side of the woofer material increasing clarity and realism by reducing resonance and ringing. This layer is not something you can see after installation, but it matters to the performance of the speaker, so it matters to us.

Proprietary Vojtko™ Crossover Networks

Vojtko Crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko. His unique approach to crossover design is just as crucial to MartinLogan's Truth in Sound as are their innovative electrostatic and Folded Motion thin-film driver technologies. A Vojtko Crossover isn't just a set of design requirements - it's a philosophy. Hand-built from the highest quality components, they avoid overly complex topologies and have a straightforward objective: breathtaking realism.
