XTC8

For true next level performance over the MC8 (its Motion CI counterpart), the XTC8 features our 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. Its unique combination of high-performance drivers and controlled dispersion allows you to control where sound is placed in a room and provides an even better experience.

The MartinLogan Motion XT CI series takes performance to the next level over Motion CI. The Folded Motion XT tweeter gives each model in the Motion XT series even more of the clarity, output and efficiency that the standard size FMT is famous for. With Motion XT, we wanted to increase all aspects of performance over the Motion series, so we didn’t just stop at the tweeter.

All Motion XT models feature woven Kevlar woofers for increased rigidity and lightness as well as a special Nomex layer on the back side of the woofer material which increases clarity and realism by reducing resonance and ringing. In addition to the larger tweeter, and lighter, stronger woofers, MartinLogan’s design and engineering team has fitted the Motion XT series with a more substantial chassis to strengthen the speaker and provide a more accurate sound, similar to a better cabinet on a traditional speaker.

The Nomex layer and the chassis are not something you can see after installation, but it matters to the performance of the speaker, so it matters to us. With Motion XT CI, the difference is in the details.

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. 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.
