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 which translates into better sound. 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, like a better cabinet on a traditional speaker. With Motion XT CI, the difference is in the details. No matter which Motion XT 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.
