Dynamo 500's high-resolution driver combines a 10-inch polypropylene cone 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, Dynamo 500's advanced-technology bass driver achieves the very low distortion necessary for proper blending with MartinLogan Folded Motion™ and electrostatic speakers.
Dynamo 500's amplifier belongs to a 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, providing a tremendous true 120 watts continuously with extremely low distortion.
Dynamo 500's connections and controls are designed to enable easy, seamless integration with any stereo music or multi-channel home theater system. Its main left and right line-level inputs feed into a precision low-pass filter with a cutoff frequency variable from 50 to 200 Hz. For systems in which a surround processor supplies the crossover, Dynamo 500 provides an LFE input low-pass filter switch that completely bypasses its internal filters.
Ports are a convenient and cost-effective way of increasing low-frequency output. Dynamo 500's dual low-turbulence ports are carefully designed to provide superb low-end efficiency while minimizing port induced distortion.
