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. Folded Motion XT tweeters advance thin-film transducer technology even further with a 40% larger radiating surface and 80x30-degree controlled dispersion. This upgrade increases audible bandwidth without sacrificing detail and reduces distortion to an incredibly low level while increasing efficiency and the tweeter's already lightning-fast response time. The result is superior realism and alarming specificity that is aurally astounding, and only by MartinLogan. 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.
Woven Kevlar Cones
All Motion XT CI speakers feature very lightweight woven Kevlar cones specifically engineered to keep pace with the lightning speed of our highest performance Folded Motion Tweeter XT. While these high-performance drivers offer both increased rigidity and lightness, we took an extra step by adding a special Nomex layer on the back side of the woofer material which increases clarity and realism by reducing resonance and ringing. This layer is not something you can see after installation, but it matters to the performance of the speaker, so it matters to us. No matter which Motion XT 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
All architectural speakers 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 all current in-ceiling speakers.
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.
