Powerful Affordable Sub with Wireless Control and Wireless Room Correction
MartinLogan's Dynamo 600X features a 240-watt peak-power amplifier, 10-inch audiophile grade woofer, extensive input options, optional wireless connectivity, control via a Bluetooth app, and Anthem Room Correction (AR). Dramatic bass detail and attack, superb extension, and room-shaking output ensure a compelling music and home theater experience.
In his August 6, 2018 review for WiFi HiFi, David Susilo calls the Dynamo 600X "an affordable little sub with an enormous growl… Listening to the Casiopea Perfect Live II LaserDisc, it's clear to me that the sub is extremely tight. When a drum is whacked, this sound is accurately reproduced with the same tightness. Bass guitars are accurately reproduced. You can hear the distinction when the bassist goes between open and closed notes as well as how tight he is gripping the strings. The bass drum kicks in Conjunction and Tetsuo Sakurai's bass guitar slaps are so impressive. Now that is accurate!"
Left and Right Two-Channel Inputs with LFE
Dynamo 600X features left and right inputs via RCA line level as well as speaker level connections. The right input doubles as an LFE input for home theater applications.
MartinLogan Sub Control App
MartinLogan’s Subwoofer Control app for iOS and Android uses a Bluetooth connection to simplify setup and configuration of Dynamo 600X. App based controls include volume level, low-pass filter (frequency and order), phase, 20–30Hz level, three preset listening modes, and control of Anthem Room Correction. A unique tone sweep feature assists users in locating areas in listening rooms where troublesome rattles or resonances may occur. A single press of a button allows listeners to initiate a tone sweep from 20–120Hz. If a rattle or resonance occurs in the room any frequency can be held, allowing the listener to investigate and identify the source of the unwanted noise.
Anthem Room Correction (ARC) Mobile App
In the lab, MartinLogan engineers strive for transparency. Outside the lab, there’s one wildcard its engineers can never account for—the listening room. The unique size and shape of a listening space (and its contents) can make bass waves do unpredictable things, greatly affecting a subwoofer’s overall performance.
The Anthem Room Correction app for iOS and Android measures low-frequency sound output in a room and compares it to optimal response curves that account for spatial anomalies. The advanced algorithms of Anthem Room Correction effectively remove anomalies, leaving only the ideal standard— realistically blended, natural-sounding bass. Dynamo 600X utilizes a Bluetooth connection with a smartphone or USB connection with a PC to run Anthem Room Correction.
Optional SWT-X Wireless Input
Although correct placement plays a key role in optimizing 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 includes a connection port for an optional wireless system.
MartinLogan’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.
Powerful, High-Excursion, Low-Turbulence, Inverted Surround Woofers
The latest generation of MartinLogan Dynamo subwoofers feature advanced-design woofers with inverted surrounds and powerful magnet, motor, and suspension designs. In front-fire mode the unique inverted surround design maximizes excursion clearance behind the grill cover. When positioned in a down-firing configuration, the inverted surround significantly reduces airflow related turbulence for an articulate and detailed low-frequency experience.
These advanced-technology woofers pair a high-power magnet structure (significantly more robust than previous generations) with low-mass diaphragms to provide massive excursions while perfectly preserving the tiniest bass detail. The exceptional damping properties of the cone ensure a smooth, non-resonant response necessary for truly seamless blending with high-performance loudspeakers. Every element of Dynamo subwoofers has been meticulously designed to deliver a staggering low-frequency performance – all without a hint of distortion.
Advanced Ultra-Efficient Switch Mode Power Supplies and Class-D Amplifiers
Dynamo subwoofer class-D amplifiers operate with extremely low levels of distortion and deliver dynamic impact with plenty of overhead. Low- noise, high-power switching power supplies produce clean power efficiently in a small space and effortlessly provide tremendous levels of current. Both feature high-quality MOSFET transistors, transformers, noise-suppression networks, and control circuitry. The switching power supply combined with reliable class-D technology means there’s virtually no energy lost in the subwoofer system.
Inverse Mathematical Equalization (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.
Low-Turbulence Ports
When properly optimized and executed, ports are a convenient, cost-effective way to increase low-frequency output. Dynamo 400 and 600X feature tuned, long low-turbulence ports designed to provide superb low-end extension while minimizing port induced distortion.
