Description
This MartinLogan Motion 30i MATTE WHITE High-Performance Folded Motion Speaker is in excellent overall preowned condition and working order! Shows only very, very minor use/handling/storage related wear, surface scratches, debris, etc. I acquired this unit from an Estate Sale at a high-end home on Lido Island in Newport Beach, CA. I removed it myself from a working system. It was in a seldom used media room. AudioQuest 33 8 banana-to-banana speaker cable included! DISCONTINUED! And the price was $899.99 when it was discontinued! Motion 30i Center Channel SpeakerSmaller 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 aluminum cone woofers, and a proprietary Vojtko crossover network. 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. Engineering, Without CompromisesWhat makes the Motion Series sound so amazing? MartinLogans 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 wont find anywhere else.Sound Inspired by Electrostatic SpeakersThe 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.Folded Motion® TweetersMartinLogans 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. Its a miracle of audio engineering thats able to deliver much of the high-frequency detail and speed of a large, dynamic electrostatic panel in a small space.Powerful Aluminum Cone Mid-Frequency and Bass DriversCustom built, low-distortion drivers pair high-power magnet structures with aluminum 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 aluminum for cones maximizes rigidity and strength of the drivers without adding excessive weight. This, along with the exceptional damping properties of aluminum, ensures the smooth, non-resonant response necessary for seamless blending with high-resolution Folded Motion tweeters. An added benefit of aluminum 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 drivers 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).Proprietary Vojtko Crossover NetworksPremium Motion Series speakers feature proprietary Vojtko crossover networks using polypropylene and low-DF electrolytic capacitors, custom-wound inductors, and thermal and current protection.Vojtko crossovers are named after MartinLogans chief audio technologist, Joe Vojtko. His unique approach to crossover design is as big of a part of the MartinLogan Sound as are electrostatic and Folded Motion thin-film driver technologies. A Vojtko crossover isnt so much a set of design requirements as it is a philosophy. Vojtko crossovers are designed in such a way that all drivers are kept within their optimal frequency range and balanced with one another. The drivers themselves are as much a part of a Vojtko crossover as are capacitors and resistors. Before the design of any crossover begins, drivers are carefully selected or designed to operate within a very intentional frequency range and with precise and predictable performance parameters. Vojtko crossovers are always built from high-quality parts, and care is taken to avoid overly complex topologies—a straightforward objective due to the careful selection of woofers and tweeters. The final (and most critical) aspect of a Vojtko Crossover is that final voicing is conducted in a space that is indicative of a real-world environment. This pragmatic approach allows MartinLogan speakers to sound their best in real-world rooms.Modern Design Featuring Luxurious FinishesDiscreetly hidden behind fabric wrapped magnetic grilles, Folded Motion and aluminum cone drivers are held securely in place beneath matte black trim that masks tweeter and woofer mounting hardware for a clean, modern aesthetic. Solid cabinets, designed to eliminate fidelity robbing vibrations, are constructed from 18mm (0.7-inch) MDF with 31mm (1.2-inch) thick front baffles. Motion 60XTi and 50XTi feature additional internal bracing to further reduce cabinet resonance.Custom 5-Way Tool-less Binding PostsPremium gold-plated 5-way tool-less binding posts assure a stable connection while accommodating bare wire, banana plug, spade lug, terminal pin, and (seldom used) alligator clip connections.SpecificationsSpecifications are subject to change without noticeFrequency Response65–25,000 Hz ±3dBRecommended Amplifier Power20—200 watts per channelHorizontal Dispersion80°Vertical Dispersion80°Sensitivity91 dB/2.83 volts/meterImpedance4 Ohms Compatible with 4, 6, or 8 Ohm rated amplifiers.Crossover Frequency400 & 2,600 HzHigh Frequency Transducer1 × 1.4 (2.6cm × 3.6cm) Folded Motion Transducer with 5.25 × 1.75 (13.3cm × 4.4cm) diaphragmLow Frequency TransducerTwo 5.5” (14cm) aluminum cone with cast polymer basket.
