Key Features

Seamlessly Integrating High-Performance Audio with Elegant Design
Emphasizing high performance and decor-friendly aesthetics, MartinLogan subwoofers expertly blend audiophile musicality and theatricality with dynamic output and accuracy in a compact design. As with all MartinLogan subwoofers, the Dynamo Series is designed to work with any speaker system while being uniquely engineered to keep pace with the exotic thin-film technologies utilized in MartinLogan loudspeakers.

Advanced Aluminum Woofers for Powerful, Distortion-Free Bass
Dynamo 12 features a custom-designed 12” aluminum woofer tuned using state-of-the-art Klippel analysis for high output and low distortion. The light weight, high strength, and excellent heat dissipation properties of aluminum make it ideal for delivering clean, powerful bass in a compact design. Meticulously engineered for maximum precision and dynamics, Dynamo subwoofers offer versatile performance to meet your musical and powerful bass needs.

Magnitude® MT-1.6kW Amplifier
Keeping Dynamo 12’s woofer fed with as much power as it can take advantage of is no easy task. Stepping up to the plate is MartinLogan’s Magnitude MT-1.6kW amplifier. Delivering up to 1600W peak (800W RMS) of clean power, ensures remarkable impact and seamless musicality at all volume levels. MartinLogan’s Magnitude amplifiers are designed to deliver their power reserves with ultra-low distortion to ensure maximum fidelity along with high output capability. MT-1.6kW maintains exceptional control over Dynamo 12’s woofer, guaranteeing precise, and powerful bass exactly when you want it.

Advanced Vojtko DSP Engine: Elevating Subwoofer Performance
Dynamo subwoofers utilize the cutting-edge, ultra-high-resolution Vojtko DSP engine, named after MartinLogan’s Chief Audio Technologist. Featuring a best-in-class 500MHz DSP with 64-bit processing, the Vojtko DSP engine is the maestro that commands all aspects of subwoofer performance in real-time. This level of computing power allows MartinLogan engineers to fine-tune performance for maximum output and fidelity with complete audible transparency as well as enabling advanced features like wireless app control, integrated wireless signal connection, and other advanced DSP functions.

Built-In Wireless Capability
Although correct placement plays a key role in optimizing subwoofer performance, getting a cable where you need it can be challenging. For ultimate convenience, our Dynamo subwoofers come with a built-in Wireless Receiver and Wireless Transmitter, making it easier than ever to eliminate cable clutter. With lossless transmission and low latency, even the most discerning enthusiast will be thrilled with the results.

Sound Structure
The cabinet plays a critical role in the sound quality of a speaker. Dynamo subwoofer cabinets are made of 1” thick MDF (Medium Density Fiberboard) with additional reinforcement on the woofer baffle. This solid construction provides a more stable platform for the high performance woofer to play from, resulting in cleaner, more articulate bass.

Robust Connectivity
In addition to the built-in wireless connection option, Dynamo™ 12 offers incredible wired installation flexibility. With both RCA and XLR LFE inputs, Stereo RCA inputs, Speaker Level inputs, and Sub Out connections, Dynamo 12 can be easily integrated into even the most complex systems. Simultaneous connections are also supported.

Reduced Vibration, Enhanced Bass
Solid bass performance is a critical component of any audio system and contributes to the visceral impact of your entertainment. Dynamo 12’s integrated anti-vibration feet improve bass performance while reducing floor and wall vibrations. By dramatically reducing energy transfer between the subwoofer and the floor, unwanted room rattles and buzzes are eliminated, resulting in tighter, cleaner bass and improved system clarity and dynamics. As a less intrusive alternative to acoustic room treatments, Dynamo 12’s integrated anti-vibration feet can also help minimize noise complaints by reducing vibration transfer into adjoining rooms.

Fine-Tune Your Subwoofer Settings with MartinLogan's Intuitive App
By far the most convenient way to adjust a subwoofer, MartinLogan’s Subwoofer Control app for iOS and Android devices allows you to easily adjust settings such as Volume, DSP Mode, Phase, and many others right from the comfort of your seat for ultimate control and ease of tuning.

Optimize Bass Performance with Award-Winning Anthem Room Correction
Dynamo 12 is compatible with the award-winning Anthem Room Correction (ARC®) system. This highly advanced software measures subwoofer performance in your room and then performs custom equalization, tuning, and calibration to achieve the highest levels of bass impact and accuracy possible for your specific installation. Requires an ARC® Calibration Microphone and a PC or Mac computer (sold separately). Buy ARC Calibration Kit

Incredible Performance Dressed In Black
Dynamo 12’s impressive performance is exclusively available in Gloss Black, featuring a beautiful, mirror-like finish accented by gunmetal trim around the woofer, and a matching trim band surrounding the cabinet. MartinLogan’s unique grille retention system, which uses no visible mounting hardware, further enhances Dynamo 12’s unique style while ensuring a clean look when the grille is removed.
