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. 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. | | | Features: | |

 Excellent SubJun 28, 2010
this is the entry level subwoofer of the martin logan line. it produces crystal clear, wall rattling low frequencies at a moderately loud volume; loud enough for my wife to ask me to turn it down. :)
if i'd had more money to spend, i would have gone for one of this speaker's bigger siblings, preferably the dynamo 1000. all in all, this an excellent sub and a good value.

 The Subewoofer you need...Feb 21, 2010
I've listened to a lot of subwoofers. I needed a new speaker to help create basis for the type of sound system I needed for my new Onkyo 607 7.2 home theater... The Martin Logan Dynamo 500 subwoofer helped to to do just that. I was amazed at the response of this subwoofer. Whether you're listening to music or a movie soundtrack, the Dynamo 500 gives a satisfactory response to fulfill the audio experience that you need for your home theater experience. When comparing this subwoofer to others within it's class, I was treated to a bass response normally espected from subwoofers at three tiimes the cost. Lovely speaker, great price.
