Martin Logan Dynamo - 10 Inch Powered Subwoofer (Silver)



Drawing on seven years of dedicated research into driver, amplifier, cabinet, control, and systems technologies, Dynamo establishes new benchmarks for performance and versatility in a subwoofer of such compact dimensions and moderate price. It is user-configurable for either front- or down-firing operation. That capability together with flexible crossover controls ensures that Dynamo can deliver excellent bass from any location in your room. No other subwoofer in its class offers Dynamo's combination of bass extension, power, and detail.

Low Distortion Aluminum Cone 10-Inch Driver

Dynamo's high-resolution driver combines a 10-inch aluminum-cone diaphragm with a high-intensity magnet structure to achieve huge excursion and output capability without sacrificing detail. By eliminating cone flexure, even at long voice-coil excursions, aluminum diaphragms help our advanced-technology bass drivers achieve the very low distortion necessary for proper blending with MartinLogan electrostatic speakers.

User-Configurable Front/Down Firing Option

To maximize performance when installed inside of a cabinet or other custom installation, Dynamo's standard down firing configuration easily converts into a front firing configuration. A grill cover and 90° RCA adaptors are provided for use in front firing applications.

Advanced Switching Amplifier

Dynamo's amplifier belongs to recently developed class of switch-mode designs that incorporate a variety of innovative techniques to reduce noise, distortion, and heat to the lowest possible levels. In particular, the switching frequency is much higher than in typical subwoofer amplifiers of this type. It can produce a true 200 watts continuously.

Musical Accuracy and Sealed Enclosure Design

Although ports are a convenient and cost-effective way of increasing low-frequency output, they rely on resonant energy in a way that impairs bass quality. A good sealed system will exhibit less transient-blurring group delay while maintaining smooth, consistent response regardless of output level or voice-coil temperature. Listen carefully to the sound of a bass drum, and you'll hear the difference.
