Martin Logan Dynamo 400 Subwoofer: A Compact Powerhouse of Bass Performance

The Martin Logan Dynamo 400 Subwoofer packs a punch in a compact form, delivering exceptional bass performance that complements your audio setup. Let's delve into the features that make this subwoofer stand out.

Versatile Input Options:

The Dynamo 400, along with its siblings Dynamo 600X, 800X, 1100X, and 1600X subwoofers, offers a range of input options to cater to various audio setups. It features left and right inputs via RCA line level, as well as speaker-level connections. For home theater enthusiasts, the right inputs of Dynamo 400 and 600X also serve as an LFE (Low-Frequency Effects) input, ensuring seamless integration into home theater applications. Dynamo 800X takes it up a notch by incorporating a discrete LFE RCA line level input. Meanwhile, Dynamo 1100X and 1600X go even further by providing both XLR and RCA inputs for LFE connections, accommodating a wide array of audio sources and systems.

Advanced Inverted Surround Woofers: 

The latest generation of MartinLogan Dynamo subwoofers, including the Dynamo 400, boasts advanced-design woofers with inverted surrounds. This unique design optimizes performance in both front-fire and down-firing configurations. In front-fire mode, the inverted surround enhances excursion clearance behind the grill cover. When positioned in a down-firing setup, it significantly reduces airflow-related turbulence, resulting in articulate and detailed low-frequency reproduction. These advanced-technology woofers combine a high-power magnet structure (more robust than previous generations) with low-mass diaphragms, enabling massive excursions while preserving the finest bass details. The exceptional damping properties of the cone ensure a smooth, non-resonant response, essential for seamless blending with high-performance loudspeakers. Every aspect of Dynamo subwoofers has been meticulously crafted to deliver astonishing low-frequency performance, free from any hint of distortion.

Class-D Amplifiers and Ultra-Efficient Power Supplies:

Dynamo subwoofers, including the Dynamo 400, employ class-D amplifiers known for their extremely low distortion levels. These amplifiers deliver dynamic impact and possess ample overhead for impactful bass. The subwoofers feature low-noise, high-power switching power supplies that efficiently produce clean power within a compact space. They effortlessly supply substantial levels of current, ensuring robust performance. Both the amplifiers and power supplies incorporate high-quality MOSFET transistors, transformers, noise-suppression networks, and control circuitry. This combination of advanced components, coupled with the class-D technology, ensures minimal energy loss in the subwoofer system.

Inverse Mathematical Equalization (IME) Filter:

The Dynamo subwoofers, including the Dynamo 400, utilize an IME filter derived from the inverse of the unfiltered driver response. This precision IME filtering results in an exceptionally accurate low-frequency response, surpassing the performance of the simple second-order high-Q filters commonly found in subwoofers within this price range.

Low-Turbulence Ports: Optimized Bass Output

When executed correctly, ports are a cost-effective way to enhance low-frequency output. Dynamo 400 and 600X subwoofers feature tuned, long low-turbulence ports designed to provide outstanding low-end extension while minimizing port-induced distortion. This ensures that you can enjoy deep and impactful bass without compromising on audio quality.

  • 8-inch Inverted Surround Poly Cone Woofer: This subwoofer features a high-quality 8-inch inverted surround poly cone woofer. The inverted surround design enhances bass performance and ensures accurate reproduction of low-frequency sounds.
  • 150 Watts (Peak) Amplifier: The built-in amplifier delivers a peak power output of 150 watts, providing the subwoofer with ample power to produce clear and impactful bass.
  • Low-Turbulence, Ported Design: The subwoofer is designed with a low-turbulence, ported enclosure. This ported design allows for efficient air movement and enhances bass response, resulting in a more dynamic and immersive listening experience.
  • RCA and Speaker Level Inputs: The subwoofer offers versatile connectivity options with both RCA and speaker level inputs. This allows you to easily integrate the subwoofer into your existing audio setup, whether you're using a dedicated subwoofer output on your receiver or connecting it to your speakers directly.
