Product Description

MartinLogan Dynamo 800X Powered Subwoofer – Black

Superb Extension And Room-Shaking Output

MartinLogan’s Dynamo 800X powered subwoofer features a 600-watt peak-power amplifier, 10-inch audiophile grade woofer, extensive input options, optional wireless connectivity, control via a Bluetooth app, Anthem Room Correction (ARC), and user-configurable front-firing or down-firing design. Dramatic bass detail and attack, superb extension, and room-shaking output ensure a compelling music and home theater experience.

Left And Right Two-Channel Inputs With LFE

Dynamo 800X features left and right input via RCA line level as well as speaker level connections. It also adds a discrete LFE RCA line level input.

Optional SWT-X Wireless Input

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.

Built-In ETC (Energy Transfer Coupler) Spikes

Dynamo 800X comes with custom ETC spikes which can be used to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality. The built-in spikes are conveniently and discretely hidden underneath the rubber feet.

MartinLogan Sub Control App

Uses a Bluetooth connection to simplify setup of Dynamo 800X. App based controls include volume level, low-pass filter, phase, 20-30Hz level, three preset listening modes, and control of Anthem Room Correction. A tone sweep feature assists users in locating areas in listening rooms where rattles or resonances may occur. A 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

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 800X utilizes a Bluetooth connection with a smartphone or USB connection with a PC to run Anthem Room Correction.

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.

Built With Outstanding Features, The Dynamo 800X Looks As Good As It Sounds
