Dynamo subwoofers pack an incredible feature list and impressive power into a stylish, compact, room friendly package. With extensive technology including built-in wireless signal connection, anti-vibration feet, and easy to use app control, Dynamo series subwoofers not only look and sound incredible, but are extremely user friendly. Although correct placement plays a key role in optimizing subwoofer performance, getting a cable where you need it can be challenging. With the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets, properly concealing the subwoofer cable is not always a simple task. To solve the problem, Dynamo subwoofers incorporate a built-in Wireless Receiver for use with the included Wireless Subwoofer Transmitter. With quick and easy setup thanks to direct pairing, eliminating cable clutter has never been easier and with lossless transmission and low latency, even the most discerning enthusiast will be thrilled with the results. Solid bass performance is a critical component of any audio system, and helps provide visceral impact to your entertainment. The integrated anti-vibration feet improve bass performance while reducing floor and wall vibrations. By dramatically reducing the energy transfer between the subwoofer and the floor, unwanted room rattles and buzzes are removed, leaving tighter, cleaner bass and improved system clarity and dynamics. As a less intrusive alternative to acoustic room treatments, the integrated anti-vibration feet on Dynamo Series subwoofers can also help minimize noise complaints by reducing vibration transfers into adjoining rooms. Ideal for all floors, hard surface and carpet spike options are both included. Dynamo Series subwoofers also take advantage of MartinLogan’s Subwoofer Control app for iOS and Android devices, allowing you to easily adjust settings like Volume, DSP Mode, Phase, and many others right from the comfort of your seat for ultimate control and ease of tuning. With 3 DSP modes for Movies, Music, or Night, you can optimize the performance of your subwoofer with a single press in the app. Choose Movie for the highest output, Music for lowest distortion, or Night to tame things down and help reduce noise complaints. With connections for both RCA and XLR LFE, Stereo RCA, and Speaker level, Dynamo Series subwoofers are an ideal choice for both Home Theater and Music applications, integrating seamlessly into any system. The Subwoofer Out connection also makes it easy to add additional subwoofers to your system, further increasing bass performance. As with all MartinLogan subwoofers, the Dynamo Series is designed to work with any speaker system while also being uniquely engineered to keep pace with the renowned clarity of MartinLogan loudspeakers. Dynamo Series subwoofers offer highly detailed and powerful bass performance in a stylish and compact package.

The ultra efficient Class-D Magnitude MT-1.6kW delivers outstanding power with incredible precision and control ensuring an immersive experience for all your favorite content.
  • Ultra High Resolution Vojtko DSP Engine: Dynamo subwoofers feature the cutting-edge Vojtko DSP engine, named after MartinLogan’s Chief Audio Technologist. With a best-in-class 500MHz DSP and 64-bit processing, it controls all aspects of subwoofer performance in real time. This level of computing power enables advanced wireless app control, integrated wireless signal connection, and other advanced functions, while providing maximum output and fidelity in any situation.
  • Integrated Anti-Vibration Feet: Dynamo’s Anti-Vibration Feet improves bass performance by dramatically reducing the energy transfer between the subwoofer and the floor. Unwanted room rattles and buzzes are removed, leaving tighter, cleaner bass and improved system clarity and dynamics. As a less intrusive alternative to acoustic room treatments, Dynamo’s integrated anti-vibration feet can also help minimize noise complaints by reducing vibration transfers into adjoining rooms.
  • Subwoofer Control 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 like Volume, DSP Mode, Phase, and many others right from the comfort of your seat for ultimate control and ease of tuning.
  • ARC Genesis Ready: Dynamo subwoofers are compatible with the award winning Anthem Room Correction 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 in your specific installation. Requires an ARC Calibration Microphone and PC or Mac computer (sold separately).
  • Built-In Wireless Connection: Although correct placement plays a key role in optimizing subwoofer performance, getting a cable where you need it can be challenging. To solve the problem, Dynamo subwoofers incorporate a built-in Wireless Receiver for use with the included Wireless Subwoofer Transmitter. With quick and easy setup, eliminating cable clutter has never been easier and with lossless transmission and low latency, even the most discerning enthusiast will be thrilled with the results.
  • Inputs: Dynamo subwoofers advanced Magnitude amplifiers have a suite of connection options available. In addition to the built-in wireless option, Dynamo subwoofers offer LFE RCA, Stereo RCA, LFE XLR, and Speaker Level Connections for maximum flexibility. Dynamo subwoofers also have an RCA Output making it easy to add additional subwoofers to any system.

Abyss Series subwoofers offer a twist on traditional subwoofer design. Combining the enhanced output of a ported sub, with the smaller footprint and natural sound of a sealed sub, MartinLogan’s Hybrid Woofer System allows Abyss models to offer the best of both worlds. Packing an incredible feature list and impressive power into a stylish, super-compact, room friendly design, Abyss subwoofers deliver performance completely unexpected from their size. With technologies including built-in wireless signal connection, anti-vibration feet, and easy to use app control, Abyss Series subwoofers not only look and sound incredible, but are extremely user friendly. Abyss subwoofers utilize a Hybrid Woofer System, which pairs two custom designed, aluminum passive radiators with its active aluminum woofer. This driver layout provides the increased output and lower distortion of a ported design, while maintaining the more compact sizing, and tighter bass typically associated with a sealed design. While much more difficult to design and engineer, this Hybrid system gives Abyss Series subwoofers the benefits of both sealed and ported designs all in one. Utilizing state-of-the-art Klippel analysis, these proprietary Aluminum drivers are specially engineered for high output and low distortion. Aluminum, chosen for its low weight, high strength, and excellent heat dissipation, is ideal for the big power and small size of Abyss Series subwoofers.
