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.

Fixed Angle Performance

The “HT” version of the XTC8 features a fixed angle mounting of the tweeter and woofer in order to provide a massive improvement in performance for listeners who are farther away. This is the perfect choice for when a speaker must be mounted apart from where the listener will be standing, walking or sitting, like in a home theater.

When being used as the front or center speaker in a home theater, the listener is typically around 10 or more feet away, yet typical in-ceiling speakers point straight down placing the sweet spot directly in front of the screen. By angling the drivers toward the listener, a very noticeable increase in performance is realized. The same holds true in whole house music systems where speakers are often located farther away from where the listener spends most of their time. In situations like this, the angled “HT” models provide a very real, and very noticeable increase in performance.

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.

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.
