• The MartinLogan Sound: Regardless of the environment, our speakers sound better, more articulate, detailed and realistic. With Controlled Dispersion and one of the clearest tweeters in the industry, our architectural models can complete with and often exceed the performance of traditional speakers.
• Controlled Dispersion: Room acoustics are extremely important. Everything in the listening room has an impact on the sound of your speakers, so we try to minimize the harmful effects by focusing the sound directly on your ears. This increases clarity, and detail regardless of the rooms design.
• Performance Meets Aesthetics: While there are many choices of CI speakers out there, MartinLogan stands out for bringing unique, high-performance technologies together in a package that perfectly blends discrete sound with noticeable quality. Performance and Aesthetics, both without compromise.
• Folded Motion Tweeter: This miracle of audio engineering gives high efficiency and low distortion a new benchmark. Our signature Folded Motion Tweeter uses an extremely lightweight diaphragm, in a space saving “folded” design, to deliver incredible detail, speed, and accuracy in a small space.
• Fiberglass Woofers: 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.
• Built-In Enclosure: The MC4 has a sealed enclosure integrated into its design, which 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.
