MC4
The Motion CI MC4 is the most compact in-ceiling speaker in the Motion CI series, featuring a 4-inch driver paired with MartinLogan's Folded Motion tweeter technology. Despite its small size, the MC4 delivers impressive clarity and detail characteristic of the Motion CI lineup. The compact footprint makes it ideal for small rooms, tight spaces, bathrooms, closets, or as Dolby Atmos height channels where larger speakers won't fit. The Folded Motion tweeter provides the speed and transparency that made the Motion series famous, while the precision-engineered 4-inch woofer delivers surprising bass for its size. Features woven fiberglass cone woofer, spring-loaded binding posts, micro-perforated paintable grille, and proprietary Vojtko crossover design. Perfect for applications where Motion CI performance is desired but space is extremely limited. Pre-construction bracket and optional square grille available separately. Voice-matched with Motion CI series for seamless system integration.
All 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. To round out the assortment, pre-construction brackets are available for all models, and all in-ceiling models have square grilles and retrofittable back enclosures available separately.

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. This thin-film transducer design packs all the accuracy and delicacy of an electrostatic panel into a small space. Folding the dramatically lightweight film into an accordion-like structure increases the surface area, giving Folded Motion tweeters eight to ten times greater surface area than typical tweeters. This ideal combination of light and large produces superior accuracy, extended frequency bandwidth and higher output capability; all with a faster, more efficient transient response, and virtually zero distortion. In these characteristics, the Folded Motion Tweeter design can mimic the performance of a large electrostatic panel in the confines of a more traditional loudspeaker enclosure.
Woven Fiberglass Cones
All Motion CI speakers feature lightweight woven fiberglass cones specifically engineered for their application to blend seamlessly with the lightning speed of our signature Folded Motion Tweeter. No matter which Motion 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.
The MartinLogan Sound
MartinLogan Motion CI speakers sound great in any room. Regardless of the environment, our 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.MartinLogan Motion CI speakers sound great in any room.

Spring-Loaded Binding Posts
With easy pre-installation access, our spring-loaded binding posts feature a large 4.5mm wire access hole and connect via banana plug, pin, or 12AWG bare wire.
Micro-Perforated Grilles
MC6-HT features an ultra-low profile, paintable, micro-perforated grilles with no visible bezel for a near-invisible integration into any wall or ceiling. A series of powerful magnets hidden inside the speaker quickly secure grilles into place, reducing the risk of warping or damage during installation.
