Regardless of the color of the drivers and enclosure, the only visible parts - once installed - will be white (white grille and trim, if this item is trimmed).
MartinLogan Motion XTC8-HT - In-Ceiling Ribbon Speaker
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 feet or farther 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 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.
