Martin Logan Dynamo 800X Active Subwoofer Black

Dynamo 800X features a 600 Watt (peak) 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- 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 Subwoofer Control app uses a Bluetooth connection to simplify setup and configuration of Dynamo 600X, 800X, 1100X, and 1600X. 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. The 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. Dynamo 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. Although 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, 1100X, and 1600X are compact, sealed subwoofer systems that minimize transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material. The cabinets are 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.Dynamo 800X, 1100X, and 1600X come 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.
