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.

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.

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. Optional square grilles are available for the MC6-HT.

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.

Optional Retrofit Enclosure
All Motion CI in-ceiling speakers have the option for a retrofittable back can or enclosure. This helps contain the sound coming off the back of the speaker to dramatically reduce unwanted sound that can travel through the floor and up into the living space above the speaker. For those desiring increased bass output, or for when sound control is not required, you can simply choose to use the MC6-HT without the optional enclosure so it can take full advantage of the larger air volume provided by the space in the ceiling.
