MartinLogan Abyss 8
Supercharged Performance. Miniaturized Size.
Abyss 8 is one of the smallest, most compact subwoofers that MartinLogan has ever built, but don’t let its small footprint fool you, it is capable of bass completely unexpected from its ultra-compact size. The key to its deceptively strong, yet detailed sound is its Hybrid Woofer System which utilizes a pair of 8” passive radiators to bolster its active 8” woofer. This woofer system is driven by powerful amplification, and a precision DSP engine, all contained inside a beautiful, yet robust, 1” thick cabinet. To complement the impressive power and musicality of Abyss 8, MartinLogan engineers included an array of connectivity options ranging from XLR to the built-in wireless option. Abyss 8 also features MartinLogan’s powerful and intuitive control app for convenient setup and adjustment, as well as being compatible with the award-winning Anthem Room Correction (ARC®) system.
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 Abyss 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.
Hybrid Woofer System – The Ultimate Compact Powerhouse
Abyss 8 is no ordinary 8” subwoofer. Featuring a unique 8” Hybrid Woofer System, Abyss 8 combines an active 8” aluminum woofer with two 8” aluminum passive radiators. This innovative design offers the enhanced output of a ported subwoofer while maintaining the compact size and tight bass associated with sealed subwoofers. Enjoy the best of both worlds without compromises like larger cabinets or port noise. Abyss 8’s custom-designed aluminum woofers are engineered for peak performance using advanced Klippel analysis. The light weight, high strength, and excellent heat dissipation properties of aluminum make it ideal for delivering clean, powerful bass in such an ultra-compact design.
Magnitude® MT-1kW Amplifier
The small but mighty Abyss 8’s Hybrid Woofer System is capable of handling a large amount of power. MartinLogan’s advanced Magnitude MT-1kW amplifier delivers up to 1000W peak (500W RMS) of clean power, ensuring incredible impact and seamless musicality. Magnitude amplifiers are designed to deliver their power reserves with ultra-low distortion to ensure maximum fidelity along with high output capability. Guaranteeing exceptional control over its long-throw 8” Hybrid Woofer System, the MT-1kW amplifier helps Abyss 8 provide an immersive audio experience from an ultra-compact subwoofer.
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 Abyss 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. Abyss subwoofer cabinets are made of 1” thick MDF (Medium Density Fiberboard) with additional reinforcement on the woofer baffles and a central brace. 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, Abyss 8 offers incredible wired installation flexibility. With both RCA and XLR LFE inputs, Stereo RCA inputs, Speaker Level inputs, and Sub Out connections, Abyss 8 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. Abyss 8’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, Abyss 8’s integrated anti-vibration feet can also help minimize noise complaints by reducing vibration transfer into adjoining rooms. Out of the box, Abyss 8’s anti-vibration feet are safe for all flooring types, and optional carpet spikes are included to further improve performance on carpeted floors.
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.
Compact Size Meets Bold Performance and Style
The ultra-compact Abyss 8 is one of the least intrusive subwoofers available, able to better fit where larger subs would seem out of place. To help further compliment your décor, Abyss 8 is available in two premium finish options. The Gloss Black version features a deep, mirror-like cabinet finish accented by gunmetal woofer trim. The Satin White version uses a bright, non-gloss cabinet finish accented by silver woofer trim. Both versions use MartinLogan’s unique, stealth grille retention system to ensure a seamless style when the grille is removed.

The Abyss 8 packs remarkably deep, tactile bass into a compact 13-inch cube, reaching into the low 20Hz region with clean authority. Audioholics found its ARC Genesis room correction meaningfully improved linearity and integration, while the triple-driver design delivers fast, articulate low end without port noise. A polished small-space powerhouse for music and cinema.

&
Cons
Larger subwoofers at a similar price can deliver greater maximum output and slam.
ARC calibration hardware and a sufficiently long USB cable are not included, making room-correction setup less convenient.
The control app does not offer a delay adjustment for integration in non-bass-managed systems.
Assessments of Build Quality, Usability, and Overall Propositions.
Bass
91/100
Audioholics heard usable output into the low-20Hz range in a desktop system, adding clearly felt depth compared with the previous subwoofer. It was praised for authoritative, clean, tactile bass and articulate speed, though the reviewer notes that larger subwoofers at similar prices can play louder and hit harder.
Integration
91/100
With ARC engaged, the reviewer found the response visibly more linear and said the Abyss 8 was better integrated with the music. The result was added low-frequency presence without a sense of distress or muddiness, rather than merely a list of adjustment options.
Dynamics
89/100
The reviewer torture-tested the subwoofer with demanding music and sweep tones and could not make it misbehave within its usable bandwidth. It delivers a visceral, tactile presentation, although its ultimate impact and output do not match physically larger competitors.
Build Quality
84/100
The review highlights the unusually substantial feel of the compact 13-inch cube, noting that it weighs nearly 50 pounds. Reviewers say little about long-term durability, amplifier reliability, or finish quality in use.
Features Usability
90/100
ARC Genesis room correction made a meaningful practical difference in the review, improving response linearity and helping the sub blend better with the system. The Abyss 8 also provides extensive Bluetooth control, flexible crossover and phase adjustment, selectable listening modes, wireless connectivity, and a useful 20-30Hz level trim.
Value for Money
90/100
At $1,400, the reviewer presents the Abyss 8 as a particularly compelling compact-performance option, saying it is very hard to exceed its performance in a 13-inch cube. Larger rivals in this price area may offer more outright output, but the MartinLogan is positioned as a strong choice for buyers who need deep, clean bass in minimal space.
