Lawrence, Kansas, October 31, 2025 – MartinLogan, the leader in electrostatic and high-performance audio technology, proudly announces the Depth® Series, an all-new line of luxury subwoofers designed to redefine what’s possible in low-frequency reproduction. Representing the pinnacle of MartinLogan’s engineering expertise, the Depth Series is designed to deliver bass that’s powerful yet impeccably clean.
Anchored by reference-grade amplification and DSP, Carbon Aerocore woofers and MartinLogan’s signature BalancedForce® woofer topology, the result is articulate, distortion-free bass that enhances everything from dedicated two-channel systems to full-scale home theaters.
“Replacing our flagship BalancedForce® Subwoofers was no easy task,” said Allan Tarrant, Senior Vice President of MartinLogan. “We decided to start from scratch and design something totally original in order to take bass performance to the next level. I am happy to report that this new Depth Series has exceeded our expectations in every way. From the overall look and feel, fit and finish, feature set, and most importantly the sound quality, they really are something truly special.”

“The BalancedForce woofer configuration has been a key part of our subwoofer technologies for decades, ever since it was first used in the Statement E2 sub-bass towers,” said Andrew Lindsey, Product Manager at MartinLogan. “Depth 212 and Depth 215 utilize this balanced, dual opposed design to great effect, using an all-new woofer cone material we call Carbon Aerocore. These cutting edge woofer cones use a tri-layer, unibody construction composed of a Carbon Fiber layer, a PMI structural foam layer, and finally a fiberglass layer. This combination provides an extreme strength to weight ratio with incredible self-dampening properties – leaving nothing but clean, detailed, articulate bass.”
Key Features and Benefits of the Depth Series:
● Carbon Aerocore Woofers: Each woofer cone features a tri-layer Carbon Fiber – PMI Structural Foam – Fiberglass construction, delivering a high strength-to-weight ratio for maximum performance. Featuring advanced triple venting – under spider, voice coils, and pole pieces – that optimizes airflow and reduces thermal compression, while dual copper shorting rings suppress distortion for effortless low-frequency performance.
● High-Power Reference Grade Class-D Amplification: Depth 212 delivers 2,200W Dynamic Peak (1,100W RMS), while Depth 215 employs dual amplifiers for 4,400W Dynamic Peak (2,200W RMS) enabling exceptional dynamic range, low distortion, and precise bass response even at the most demanding listening levels.
● 64-bit Vojtko DSP Engine: Powered by a class leading 500MHz, 64-bit digital signal processor, this proprietary DSP engine actively monitors and optimizes every aspect of performance in real time for superior accuracy and effortless musicality.
● Convection-Cooled Concealed Amplifier Design: The amplifier and connections are hidden within a sleek rear trim assembly featuring dual aluminum heatsinks that also provide airflow for the convection cooling system, maintaining amplifier performance and keeping cable management discreet.
● Concealed Touch Control Interface (TCI): The TCI offers full subwoofer control without the MartinLogan Control app. Six backlit touch points and an LED display provides intuitive access to all settings, while customizable backlighting lets users tailor the look – or turn it off entirely for a stealth appearance.
● Integrated Anti-Vibration Feet: Works in tandem with Depth’s robust cabinet design and BalancedForce Woofer System to effectively eliminate the energy transfer between the subwoofer and the floor, reducing unwanted room rattles and buzzes, leaving tighter, cleaner bass and improved system clarity and dynamics.
● Anthem Room Correction (ARC®) – Supports the award-winning ARC® system for precise room equalization, tuning, and calibration, ensuring maximum bass impact and flawless integration in any listening environment. The system includes a premium calibration microphone kit, enabling a quick and effortless setup.
● Comprehensive Connectivity: Depth Series offers a full suite of wired connection options, including XLR Left and Right, XLR LFE (Right XLR), dedicated RCA LFE, RCA Left and Right, Speaker level (via banana plugs), and RCA Sub Out. For added flexibility, the system also includes lossless wireless subwoofer connectivity.
The Depth Series subwoofers are designed to seamlessly blend uncompromising low-frequency performance with timeless, luxury design. Every aspect of these systems – from the expertly sculpted cabinet to the concealed, convection-cooled amplifier– fuses form and function in perfect harmony. With Depth 212 and Depth 215, high performance and elegant design go hand in hand, delivering bass that is as clean and powerful as it is beautifully presented.
