Martin Logan Motion MC6 Motion CI Series 6.5" In-Ceiling Speaker (Each)

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 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.

Micro-Perforated Grilles
All Motion CI models feature 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. Optional square grilles are available for the MC8, MC6-HT, MC6 and MC4.

Proprietary Vojtko Crossover Networks
Vojtko Crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko.

His unique approach to crossover design is just as crucial to MartinLogan's Truth in Sound as are our innovative electrostatic and Folded Motion thin-film driver technologies. A Vojtko Crossover isn't just a set of design requirements; it's a philosophy.

Vojtko Crossovers are hand-built from the highest quality components and avoid overly complex topologies. This crossover has a straightforward objective: breathtaking realism.

Hand-Selected Components
In designing each crossover topology, we take the drivers themselves into consideration. Carefully selected drivers, engineered for specific performance characteristics, are kept within their optimal frequency range by the custom Vojtko Crossover.

Each crossover is handcrafted using exceptional polypropylene and polyester capacitors, custom wound and large steel laminate low-DCR inductors, and double thick PCBs. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source. It's a recipe for vanishingly low distortion and seamless driver integration.

The most critical aspect of a Vojtko Crossover design is the final voicing, always conducted in a real-world environment. This uniquely pragmatic approach guarantees that even the most amazing MartinLogan loudspeakers deliver Truth in Sound in any room, including yours.
