MartinLogan Motion Series 6" In-Ceiling Speakers (Single)
MartinLogan Motion CI Series speakers feature our signature Folded Motion Tweeter or FMT. This innovative piece of audio technology provides incredible detail, precise clarity, clean output and high efficiency in a small but mighty package. Pairing this tweeter with lightweight woven fiberglass woofers means that Motion CI delivers a clean and balanced sound that is perfectly suited for any application. Whether you listen to music, movies or a little bit of everything, Motion CI gives you a true high-end audio experience at an affordable price.
By far the most popular size for in-ceiling speakers, the MC6 features a 6.5” woofer with higher power handling, greater output capability, and improved bass response over the smaller MC4. This model works without a built-in enclosure to allow the speaker to use more airspace for higher performance. For applications where sound control is desired, an optional retrofittable back enclosure is available separately. As with all Motion series CI speakers, the MC6 uses MartinLogan’s signature Folded Motion Tweeter for precise clarity and incredible realism to meet all your entertainment needs.
The MC6-HT is the angled version of the MC6. By designing the speaker with a fixed tweeter and woofer angle, MartinLogan was able to tune the performance of the speaker far more accurately than universal pivoting designs. By eliminating the variable of tweeter and woofer angle, the precision Vojtko crossover network has been tuned for more accurate and predictable results. The MC6-HT is recommended for applications where the listener will spend most of their time not directly underneath the speaker.
