Martin Logan Dynamo 800X Active Subwoofer comes equipped with a peak 600 Watt amplifier, a 10-inch top-quality woofer, a wide range of input choices, the option for wireless connectivity, and can be controlled via a Bluetooth app. It also includes Anthem Room Correction (ARC®) and a user-configurable design that allows for front- or down-firing. With its exceptional bass detail and attack, exceptional extension, and powerful output, this device delivers an immersive and impressive music and home theatre experience.
MARTIN LOGAN SUB CONTROL APP: The Subwoofer Control app from Martin Logan simplifies the setup and configuration of Dynamo 600X, 800X, 1100X, and 1600X via Bluetooth connectivity. Users can adjust various controls through the app, including volume level, low-pass filter (frequency and order), phase, 20-30Hz level, three preset listening modes, and Anthem Room Correction. A unique feature of the app is the tone sweep, which enables users to locate troublesome rattles or resonances in their listening room. By pressing a button, the app initiates a tone sweep from 20-120Hz, and if a rattle or resonance occurs, the listener can hold any frequency to identify the source of the unwanted noise.
ARC MOBILE APP: Martin Logan engineers aim for transparency in the lab, but the listening room poses a wildcard they cannot predict. The room's size, shape, and contents can cause unpredictable behaviour in bass waves, significantly impacting a subwoofer's performance. To address this issue, Anthem Room Correction measures low-frequency sound output and compares it to optimal response curves that account for spatial anomalies. The advanced algorithms effectively remove anomalies, leaving only natural-sounding bass that blends well with other speakers. The Dynamo 600X, 800X, 1100X, and 1600X feature Bluetooth connectivity with a smartphone or USB connection to a PC to run Anthem Room Correction.
OPTIONAL SWT-X WIRELESS INPUT: Although correct placement plays a key role in optimising subwoofer performance, sometimes it imposes the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, Dynamo 600X, 800X, 1100X, and 1600X include a connection port for an optional wireless system. Martin Logan’s new SWT-X Wireless Subwoofer System (sold separately) incorporates the latest in wireless audio transmission technology, including 2.4GHz dynamic frequency selection, forward error correction, and a range up to 50 feet. Easy to install in the subwoofer, the SWT-X receiver requires no external power source or audio connections.
LEFT AND RIGHT 2-CHANNEL INPUTS
Dynamo 400, 600X, 800X, 1100X, and 1600X subwoofers feature left and right input via RCA line level as well as speaker level connections.
LFE HOME Theatre INPUT
Dynamo 400 and 600X’s right inputs double as an LFE input for home theatre applications. Dynamo 800X ups the ante by adding a discrete LFE RCA line level input. Dynamo 1100X and 1600X go one step further by adding both XLR and RCA inputs for LFE connection.
12V TRIGGER INPUT
Dynamo 800X, 1100X, and 1600X feature 12V Trigger Inputs, allowing an external device to turn the subwoofer on and off.
SIMULTANEOUS LFE AND 2-CHANNEL CONNECTIONS
Dynamo 800X, 1100X, and 1600X subwoofers features left and right input via robust connection and a control system that allows simultaneous connection of both 2-channel stereo music and multi-channel home theatre and allows each source to have individual crossover and level settings, giving listeners a perfect performance in every application. LFE inputs use no low-pass filter, leaving crossover control to the processor. Left and right inputs integrate discrete user-adjustable low-pass filters allowing different level and crossover points when playing back two channel music.
POWERFUL, HIGH-EXCURSION, LOW-TURBULENCE, INVERTED SURROUND WOOFERS The latest generation of Martin Logan Dynamo subwoofers boasts advanced-design woofers that have inverted surrounds and powerful magnet, motor, and suspension designs. The unique inverted surround design maximises excursion clearance behind the grill cover when in front-fire mode. Meanwhile, the inverted surround significantly reduces airflow-related turbulence in a down-firing configuration for a detailed and articulate low-frequency experience. These woofers use a high-power magnet structure that is more robust than previous generations and low-mass diaphragms, allowing for massive excursions while preserving the tiniest bass details. The exceptional damping properties of the cone ensure a smooth and non-resonant response that is necessary for seamless blending with high-performance loudspeakers. Every element of the Dynamo subwoofers has been meticulously designed to deliver a staggering low-frequency performance without any distortion.
ADVANCED ULTRA-EFFICIENT SWITCH MODE POWER SUPPLIES AND CLASS-D AMPLIFIERS The class-D amplifiers of Dynamo subwoofers produce dynamic impact with ample overhead while operating with extremely low distortion levels. The low-noise, high-power switching power supplies generate clean power efficiently in a compact space and effortlessly provide significant levels of current. These components include high-quality MOSFET transistors, transformers, noise-suppression networks, and control circuitry. The use of a switching power supply in combination with reliable class-D technology means that there is minimal energy loss in the subwoofer system.
UNIQUE FRONT-FIRING OR DOWN-FIRING DESIGN
Transforming the Dynamo 800X, 1100X, and 1600X subwoofers from a regular down-firing position to a front-firing setup is a simple task that requires no special skills or tools. This can be easily done when the subwoofer is placed in a cabinet or another concealed spot. Additionally, a grille is supplied to use in front-firing applications.
INVERSE MATHEMATICAL Equalisation (IME) FILTER The IME filter used in the Dynamo subwoofers is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response—superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.
SEALED CABINET WITH EXTENSIVE INTERNAL BRACING Although ports, when correctly designed, are a convenient and cost-effective way of increasing low-frequency output, when used in small cabinets their reliance on resonant energy can impair bass quality. Dynamo 800X, 1100X, and 1600X are compact, sealed subwoofer systems that minimise transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material. The cabinets are constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing provides a stable foundation for the woofer, while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.
BUILT-IN ETC™ (ENERGY TRANSFER COUPLER) SPIKES Custom ETC spikes are included with the Dynamo 800X, 1100X, and 1600X to provide improved stability on thick carpets or a tighter coupling between the subwoofer and the floor, resulting in better overall sound quality. The built-in spikes are discreetly tucked away beneath the rubber feet, making them both convenient and inconspicuous.

Frequency response is a measure of how well an audio device (such as a speaker, headphone, microphone, or amplifier) reproduces sound across a range of frequencies. It is a crucial factor in determining the overall audio quality and the ability of a device to accurately reproduce different pitches and tones in audio content.
Frequency response is usually represented graphically, with frequency (measured in Hertz, or Hz) on the x-axis and amplitude (usually measured in decibels, or dB) on the y-axis. The graph, known as a frequency response curve, shows how the device responds to different frequencies. The flatter the curve, the more neutral and accurate the frequency response.
Here are some key points to understand about frequency response:
Flat Frequency Response: An ideal audio device would have a completely flat frequency response curve, meaning it reproduces all frequencies equally accurately. In practical terms, achieving a perfectly flat response is challenging, but high-quality audio equipment aims to keep the response as flat and consistent as possible.
Bass and Treble Response: The frequency response curve helps visualise how well a device reproduces both low-frequency (bass) and high-frequency (treble) sounds. The bass and treble regions of the curve provide insights into the device's ability to handle deep lows and crisp highs.
Roll-Off and Extremes: A device's frequency response curve might show a gradual roll-off at very low or very high frequencies. This is natural and often a design choice to prevent distortion or strain at extreme ends of the frequency spectrum.
Measurement Standards: Frequency response measurements are typically conducted under controlled laboratory conditions using specialised equipment. It's important to consider whether the measurements were taken in an anechoic chamber (where reflections are minimised) or in a real-world environment, as this can affect the results.
Human Perception: While a flat frequency response is desirable, human perception of sound can vary. Some listeners might prefer a slight boost in bass or treble frequencies, known as "voicing," for a more pleasing or exciting sound.
Room Acoustics: It's important to note that the frequency response of an audio device can be influenced by the acoustics of the room in which it is placed. Room reflections, resonances, and other factors can affect how sound is perceived.
Comparing Devices: When comparing the frequency response of different audio devices, it's important to consider the context, the intended use, and your personal preferences. A device with a flat response might not always be the best choice if you're looking for a specific sound signature.
Frequency response is just one aspect of audio quality, and a device's performance should be evaluated in conjunction with other factors such as distortion, sensitivity, and soundstage. When choosing audio equipment, it's a good idea to listen to demonstrations whenever possible and read reviews from reputable sources.
Power, in the context of audio and video systems, refers to the electrical energy needed to operate and drive various components within these systems. It plays a crucial role in determining the performance, volume, and overall quality of audio and video playback. The power requirements and considerations vary depending on the specific components and setups being used.
Here's how power is relevant in audio and video systems:
Audio Systems:
Amplifiers: Power amplifiers are responsible for increasing the amplitude of audio signals to drive speakers. The power output of an amplifier is typically measured in watts per channel (WPC). Higher-powered amplifiers can deliver louder and more dynamic audio, especially for large rooms or high-performance setups.
Speaker Power Handling: Speakers have power handling capabilities that indicate the maximum amount of power they can handle without distortion or damage. Matching the amplifier's power output to the speaker's power handling is important for optimal performance and longevity.
Efficiency and Distortion: Adequate power is essential to prevent underpowering, which can lead to distortion at higher volumes. Insufficient power can cause clipping and distortion, negatively impacting audio quality.
Subwoofers: Powered subwoofers require sufficient power to reproduce low-frequency sound accurately. Subwoofers often have their own built-in amplifiers to drive the dedicated low-frequency drivers.
Video Systems:
Display Devices: Video displays, such as TVs and projectors, require power to illuminate the screen and produce images. The power consumption of displays varies based on factors like screen size, technology (LCD, OLED, etc.), and brightness settings.
Projectors: High-powered projectors are needed for larger screens or brighter environments. Projector power is measured in lumens, indicating the brightness output.
AV Receivers: AV receivers act as central hubs for audio and video systems. They require power to process and amplify audio signals, as well as to handle video switching and processing tasks.
Media Players and Streaming Devices: Devices that play audio and video content, such as Blu-ray players, streaming devices, and gaming consoles, require power to operate and provide content to displays and audio systems.
Audio-Video Processors: Audio-video processors, often used in advanced home theatre setups, require power to handle complex audio decoding and video processing tasks.
Power Management: Efficient power management, including energy-saving modes and automatic power-off features, can help reduce energy consumption and extend the lifespan of components.
Power Distribution: Ensuring proper power distribution and surge protection is crucial to safeguarding equipment from power fluctuations, voltage spikes, and potential damage.
The power requirements for audio and video systems depend on the desired performance, room size, speaker sensitivity, and other factors. Adequate power ensures clean and accurate audio reproduction, clear video playback, and an overall enjoyable and immersive entertainment experience. When setting up audio and video systems, it's important to consider the power needs of each component and ensure proper power management for optimal performance and longevity.
