Martin Logan Motion 30i Centre Channel Speaker
Smaller multi-channel audio systems will benefit from the significant dynamic impact and detailed imaging revealed by a Folded Motion® tweeter and dual, rear-vented 5.5-inch aluminium cone woofers, and a proprietary Vojtko crossover network. The Martin Logan Motion 30i delivers the classic broad soundstage of the Motion Series from a newly designed enclosure enhanced by the slightest of modifications, including the drive-stabilizing dust cap design and stiffened motor suspension. The speaker’s cabinet sports a reinforced baffle and a fabric grille. Available in two stylish finishes: gloss black, matte white.
Engineering, Without Compromises
What makes the Motion Series sound so amazing? MartinLogan’s dedicated in-house engineering and design team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering and time-honored cabinet construction techniques. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price. Our ‘no compromise’ philosophy gives Motion Series a unique sound you won’t find anywhere else.
Sound Inspired by Electrostatic Speakers
The success of the Motion Series is directly attributed to its close relation to MartinLogan’s legendary ultra-high-end electrostatic loudspeakers. The desire to transmute that level of performance into a more traditional loudspeaker at a more affordable price drove the initial design imperatives that created the Motion Series. With its sleek and modern design, the Motion Martin Logan 30i becomes a visual centrepiece in your home theatre setup, captivating both the eyes and the ears. Its compact size allows for seamless integration into any living space, while its audio prowess shines brightly, transforming your entertainment experience.
Folded Motion® Tweeters
MartinLogan’s signature Folded Motion tweeter utilizes an extremely low mass diaphragm that “squeezes” air, thus demanding 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’s able to deliver much of the high-frequency detail and speed of a large, dynamic electrostatic panel in a small space.
Powerful Aluminium Cone Mid-Frequency and Bass Drivers
Custom built, low-distortion drivers pair high-power magnet structures with aluminium cone diaphragms to deliver massive excursion and sound output, preserve minute bass details, and maximize power handling capability, all without a hint of distortion. A unique concave dust cap design reinforces the strength and rigidity of the cone while reducing break up modes.
The use of aluminium for cones maximizes rigidity and strength of the drivers without adding excessive weight. This, along with the exceptional damping properties of aluminium, ensures the smooth, non-resonant response necessary for seamless blending with high-resolution Folded Motion tweeters. An added benefit of aluminium is its outstanding thermal conduction capability which allows cones to serve as efficient heat sinks for voice coils.
To deliver accuracy in the critical midrange, mid-frequency drivers feature a specially engineered “stiff” suspension. Stiffening the suspension (the spider and surround) raises the driver’s resonant frequency and optimizes its performance to achieve a natural roll-off and inherently operate within an ideal range for a mid-frequency reproduction (as opposed to a comparably sized woofer).
The Martin Logan Motion 30i will allow you to indulge in the pleasure of hearing crisp and richly detailed dialogue, perfectly balanced with the accompanying soundtrack. Lose yourself in the immersive audio landscape, where sound is no longer just heard, but felt deep within your soul.
