MartinLogan 650-Watt Down Firing 12" Subwoofer DYN1100XD

The Dynamo subwoofer feature left and right input via RCA line level as well as speaker level connections.

The Dynamo feature 12V Trigger Inputs, allowing an external device to turn the subwoofer on and off.

The Dynamo features left and right input via robust connection and a control system that allows simultaneous connection of both 2-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.

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.

An IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response - far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.

A good sealed system will typically exhibit less transient-blurring group delay while maintaining smooth, consistent response regardless of music or movie source material. On the outside, this subwoofer's cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing acts an excellent baffle for the woofer while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.

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. The Dynamo is compact, sealed subwoofer systems that minimize transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material. The cabinets 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.
