Martin Logan Dynamo 300 Black Subwoofer, Model DYN300D (Sold As Each)
Affordable Low-Frequency Accuracy
Every element of Dynamo 300, from driver to amplifier to crossover to cabinet,
is meticulously designed and manufactured to our highest standard. The result
is staggering low-frequency performance for a subwoofer of its size and price.
Perfect for either home theater or stereo applications, the Dynamo 300 is built
with high-density materials to minimize cabinet resonance and provide a solid
foundation for the high-output 8-inch woofer and high-current 75-watt, 150-watt
peak amplifier. 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 300's high-resolution driver combines a 8-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 300's advanced-technology bass driver achieves the very
low distortion necessary for proper blending with MartinLogan FoldedMotion
and electrostatic speakers.
- 75-watt (150-watt peak) Amplifier
Dynamo 300'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 75 watts continuously with extremely low distortion.
- Low-Turbulence Port
Ports are a convenient and cost-effective way of increasing low-frequency
output. Dynamo 300's low-turbulence port is carefully designed to provide
superb low-end efficiency while minimizing port induced distortion.
- High-Density Cabinet Construction
Dynamo 300's high-density cabinet is carefully designed to minimize cabinet-induced
resonances and provide an ideal baffle for linear operation of Dynamo 300's
long-excursion 8-inch low-distortion woofer.
- Seamless System Integration: Engineered for Stereo and Home Theater
Dynamo 300'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 45 to 150 Hz. For systems in which a
surround processor supplies the crossover, Dynamo 300 provides an LFE input
low-pass filter that completely bypasses its internal filters.
