Martin Logan - Subwoofer Setup and Optimization

Compact, Affordable Performance

No other subwoofer offers Dynamo 500's bass extension, power, and detail at such an affordable price. Perfect for either home theater or stereo applications, the Dynamo 500 is solidly built with high-density materials to minimize cabinet resonance and provide a foundation for the high-output 10-inch woofer and high-current 120-watt RMS, 360-watt peak amplifier. Additionally, dual rear-mounted low-turbulence ports maximize bass output while minimizing port induced distortions.

Whether you are looking for high performance bass to enhance your music experience or take your home theater system to the next level, a new Dynamo family subwoofer should be at the top of your list.


  • 10-Inch Low-Distortion Woofer 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 ATF (Advanced Thin Film) and electrostatic speakers.
  • 120-watt (360-watt peak) Amplifier 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.
  • Dual Low-Turbulence Ports 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.
  • High-Density Cabinet Construction Dynamo 500's high-density cabinet is carefully designed to minimize cabinet-induced resonances and provide an ideal baffle for linear operation of Dynamo 500's long-excursion 10-inch low-distortion woofer.
  • Seamless System Integration: Engineered for Stereo and Home Theater 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.


  • Frequency Response 29–200 Hz ±3dB; Anechoic through LFE effects input
  • Low Pass Filter Frequency 50–200 Hz
  • Low Frequency Transducer 10" (25.4cm) high excursion, polypropylene cone with extended throw drive assembly; ported

  • Audio Controls Low Pass Filter Switch: Bypass (LFE In), Variable (Left and Right In)
  • Inputs Left and Right/LFE RCA line level

    Comments about Martin Logan Dynamo 500 Black Subwoofer:

    Already have the JBL SB 400 unit for the bedroom and decided to go up a level for the living room. The Martin Logan Vision soundbar coupled with the subwoofer via the wireless system is a clear winner.

      Used in larger room background music system. Nice job filling in the low end. Glad I got the 500 and not the new 8" unit just out from ML.
