Dynamo 800X ups the ante by adding a discrete LFE RCA line level input. Dynamo 1100X and 1600X go one step further by adding both XLR and RCA inputs for LFE connection.
POWERFUL, HIGH-EXCURSION, LOW-TURBULENCE, INVERTED SURROUND WOOFERS 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. ADVANCED ULTRA-EFFICIENT SWITCH MODE POWER SUPPLIES AND CLASS-D AMPLIFIERS 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 theres virtually no energy lost in the subwoofer system.
INVERSE MATHEMATICAL EQUALIZATION (IME) FILTER The 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 responsesuperior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.
LOW-TURBULANCE PORTS When properly optimized and executed, ports are a convenient, cost- effective way to increase low-frequency output. Dynamo 400 and 600X feature tuned, long low-turbulence ports designed to provide superb low-end extension while minimizing port induced distortion.
