Exciting 3.1-Channel Speaker and Sub ComboEnjoy this powerful yet compact 3.1-channel speaker and subwoofer kit from MartinLogan, starring two Motion 4i bookshelf speakers for front channels, one MartinLogan Motion 8i center channel speaker, and a MartinLogan Dynamo 800X powered subwoofer. MartinLogan Motion 4i Bookshelf SpeakerThe term 'bookshelf speakers' sounds so stuffy. It just doesn't do justice to the sleek and windswept look of MartinLogan's awesome Motion 4 speakers. Set 'em next to your TV, mount them on the wall, or place them on a stand. They work great and sound BIG as front channel speakers in a mid-size home theater system or as surround speakers in a larger set-up. The Motion 4i is particularly well equipped to excel with two-channel music as well as with multi-channel entertainment sources. Its driver complement consists of a 1" x 1.4" Folded Motion™ high-frequency transducer with a 5.25" x 1.75" diaphragm plus a 4" low frequency driver with stamped steel basket, non-resonant asymmetrical chamber format, and rigid structured dust cap to reduce cone break-up modes. The Motion i SeriesInspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 2i, 4i, 6i, and 8i feature exquisite Folded Motion tweeters and powerful bass technology in compact and affordable packages. Key to performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (much larger than a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jaw-dropping clarity certain to inspire envy in audiophiles and non-audiophiles alike. Precision Vojtko™ crossover topology features custom air core coil inductors, low DCR steel laminate inductors, and polyester film and low DF electrolytic capacitors for a seamless sonic presentation. Flexible installation options allow table top or on-wall installation of all four speakers. Motion 2i and 4i bookshelf speakers can also mount upside down to facilitate placement high on a wall. Motion 6i and 8i can mount horizontally or vertically around a wall-mounted flat screen television. Engineering GeniusWhat makes the Motion i Series sound so amazing? MartinLogan's dedicated in-house engineering team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering. The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price. Folded Motion™ TweeterMartinLogan's exclusive and highly innovative Folded Motion™ Tweeter helps gives Motion i speakers their fantastically realistic highs. Lightning fast transient response, combined with a large surface area creates clear, highly dynamic, and precise sound. The Folded Motion™ Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90 percent less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lighting fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage. Vojtko™ CrossoverContributing to the superb performance is the legendary Vojtko™ crossover. It is carefully hand-built using only the finest polyester film and low DF electrolytic capacitors, custom air-core coils, and low DCR steel laminate inductor for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source. Curve AppealComplementing Motion's sonic accuracy is elegant yet understated styling. Flawless high-gloss, piano black finishes and subtle curves, along with MartinLogan's signature perforated grille, gives Motion i Series speakers an elegant and timeless look. Tower models feature a real-wood veneer finish and a stylish aesthetic certain to blend with any decor. Hook-ups, SimplifiedConvenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. So simple, you'll actually enjoy hooking up these speakers. MartinLogan Motion 8i Center SpeakerMartinLogan's Motion 8i is a sleek, high performance center channel speaker that looks great with today's TVs. Inspired by the clarity and detail of MartinLogan's ultra-high-end electrostatic loudspeakers, Motion 8i features a Folded Motion™ tweeter and powerful bass technology in a compact and affordable package. Set it under you set or mount it on the wall for superb sound quality. The Motion 8i excels with music, movies, and other multi-channel entertainment sources. Its driver complement consists of a 1" x 1.4" Folded Motion™ high-frequency transducer with a 5.25" x 1.75" diaphragm plus two 4" low frequency drivers with stamped steel basket in a non-resonant asymmetrical chamber format wit rigid structured dust cap to reduce cone break-up modes. MartinLogan Dynamo 800X Powered SubwooferMartinLogan's Dynamo 800X powered subwoofer features a 600-watt peak-power amplifier, 10-inch audiophile grade woofer, extensive input options, optional wireless connectivity, control via a Bluetooth app, Anthem Room Correction (ARC), and user-configurable front-firing or down-firing design. Dramatic bass detail and attack, superb extension, and room-shaking output ensure a compelling music and home theater experience. "MartinLogan's Dynamo 800X is the first subwoofer I've reviewed that combines digital control, signal connection, and room correction – all three wirelessly – in a small, powerful package," raves Larry Greenhill in Larry Greenhill in his February 2019 review for Stereophile. "I heard no difference between the wireless and wired connections," Larry Greenhill continues. "And, once I'd found good positions for the Dynamos, set their output level correctly, and identified their optimal crossover frequencies, their sound seamlessly blended with that of my Quad electrostatics, deepening the ESL-989's soundstages and deep-bass extension and expanding their dynamic range, and enhancing their three-dimensionality, all at a price far below that of larger subwoofers I've reviewed." "Virtually Invisible""For the price and feature set, the Dynamo 800X accomplishes exactly what it needs to do, and unlike other subwoofers, you can achieve its full potential without needing a high-end receiver that can handle room correction," notes Chris Heinenon, Reference Home Theater, October 2018. "With integrated Anthem Room Correction, you get a flat bass response in your room without much work, and the transition from the sub to the speakers is virtually invisible." Left and Right Two-Channel Inputs Plus LFEDynamo 800X features left and right input via RCA line level as well as speaker level connections. It also adds a discrete LFE RCA line level input. Simultaneous LFE and Two-Channel ConnectionsThe Dynamo 800X features left and right input via robust connections and a control system that allows simultaneous connection of both two-channel stereo music and multi-channel home theater and allows each source to have individual crossover and level settings, giving listeners a perfect performance in every application. LFE inputs use no low-pass filter, leaving crossover control to the processor. Left and right inputs integrate discrete user-adjustable low-pass filters, allowing different level and crossover points when playing back two channel music. MartinLogan Sub Control AppMartinLogan's Subwoofer Control app for iOS and Android uses a Bluetooth connection to simplify setup and configuration of the Dynamo 800X. App based controls include volume level, low-pass filter (frequency and order), phase, 20–30Hz level, three preset listening modes, and control of Anthem Room Correction. A unique tone sweep feature assists users in locating areas in listening rooms where troublesome rattles or resonances may occur. A single press of a button allows listeners to initiate a tone sweep from 20–120Hz. If a rattle or resonance occurs in the room any frequency can be held, allowing the listener to investigate and identify the source of the unwanted noise. Anthem Room Correction (ARC) Mobile AppIn the lab, MartinLogan engineers strive for transparency. Outside the lab, there's one wildcard its engineers can never account for—the listening room. The unique size and shape of a listening space (and its contents) can make bass waves do unpredictable things, greatly affecting a subwoofer's overall performance. The Anthem Room Correction app for iOS and Android measures low-frequency sound output in a room and compares it to optimal response curves that account for spatial anomalies. The advanced algorithms of Anthem Room Correction effectively remove anomalies, leaving only the ideal standard— realistically blended, natural-sounding bass. Dynamo 800X utilizes a Bluetooth connection with a smartphone or USB connection with a PC to run Anthem Room Correction. Optional SWT-X Wireless InputAlthough correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, Dynamo 800X includes a connection port for an optional wireless system. MartinLogan's new SWT-X Wireless Subwoofer System (sold separately) incorporates the latest in wireless audio transmission technology, including 2.4GHz dynamic frequency selection, forward error correction, and a range up to 50 feet. Easy to install in the subwoofer, the SWT-X receiver requires no external power source or audio connections. Unique Front-Firing or Down-Firing DesignWhen placed in a cabinet or other discreet location, the Dynamo 800X subwoofer can easily convert from standard down-firing to front-firing orientation, with no tools or special skills required. A grille is provided for use in front-firing applications. Powerful, High-Excursion, Low-Turbulence, Inverted Surround WoofersThe latest generation of MartinLogan Dynamo subwoofers feature advanced-design woofers with inverted surrounds and powerful magnet, motor, and suspension designs. In front-fire mode the unique inverted surround design maximizes excursion clearance behind the grill cover. When positioned in a down-firing configuration, the inverted surround significantly reduces airflow related turbulence for an articulate and detailed low-frequency experience. These advanced-technology woofers pair a high-power magnet structure (significantly more robust than previous generations) with low-mass diaphragms to provide massive excursions while perfectly preserving the tiniest bass detail. The exceptional damping properties of the cone ensure a smooth, non-resonant response necessary for truly seamless blending with high-performance loudspeakers. Every element of Dynamo subwoofers has been meticulously designed to deliver a staggering low-frequency performance – all without a hint of distortion. Advanced Ultra-Efficient Switch Mode Power Supplies and Class-D AmplifiersDynamo subwoofer class-D amplifiers operate with extremely low levels of distortion and deliver dynamic impact with plenty of overhead. Low- noise, high-power switching power supplies produce clean power efficiently in a small space and effortlessly provide tremendous levels of current. Both feature high-quality MOSFET transistors, transformers, noise-suppression networks, and control circuitry. The switching power supply combined with reliable class-D technology means there's virtually no energy lost in the subwoofer system. Inverse Mathematical Equalization (IME) FilterThe IME filter used in the Dynamo subwoofers is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response—superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range. Sealed Cabinet with Extensive Internal BracingAlthough ports, when correctly designed, are a convenient and cost-effective way of increasing low-frequency output, when used in small cabinets their reliance on resonant energy can impair bass quality. Dynamo 800X is a compact, sealed subwoofer system that minimizes transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material. The cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing provides a stable foundation for the woofer, while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels. Built-In ETC™ (Energy Transfer Coupler) SpikesDynamo 800X comes with custom ETC spikes which can be used to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality. The built-in spikes are conveniently and discretely hidden underneath the rubber feet. Kit Includes
