Starting Fresh: The Birth of the Depth Series

Replacing a flagship model isn't a small feat, especially when it’s as revered as MartinLogan’s BalancedForce® Subwoofers. Allan Tarrant, Senior Vice President at MartinLogan, shared how the company chose to completely rethink and redesign their subwoofers to leap beyond previous performance levels.

“Replacing our flagship BalancedForce® Subwoofers was no easy task. We decided to start from scratch and design something totally original in order to take bass performance to the next level. 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.”
— Allan Tarrant

The Depth Series pushes the envelope in both sound fidelity and style, packing cutting-edge technology into a stunning package that suits the most discerning audiophiles and home theater enthusiasts.

BalancedForce Meets Carbon Aerocore: A Woofer Revolution

Andrew Lindsey, MartinLogan’s Product Manager, emphasized how the famed BalancedForce woofer technology has been a staple of their subwoofers since the days of the Statement E2 sub-bass towers. This dual-opposed woofer configuration cancels out cabinet vibrations, producing bass that’s tight and pure.

The Depth 212 and Depth 215 models take this concept further by incorporating the brand-new Carbon Aerocore woofer cones, crafted from a tri-layer unibody construction:

• Carbon Fiber layer for strength
• PMI structural foam layer for lightweight durability
• Fiberglass layer for smooth sound damping

This combination yields an ultra-strong yet featherweight cone that self-dampens, resulting in bass that's as articulate as it is powerful without any distortion creeping in.

Key Features and Benefits of the Depth Series

What truly makes the Depth Series stand out? Let’s break down the highlights:

• BalancedForce Woofer System: Two active woofers—12-inch in the Depth 212, 15-inch in the Depth 215—work in perfect opposition. This setup wipes out cabinet resonance and distortion, delivering pure, articulate bass that you can feel in your bones.
• Carbon Aerocore Woofers: Their tri-layer design optimizes strength-to-weight ratio. Triple venting allows for better airflow, reducing thermal compression. Plus, dual copper shorting rings suppress distortion, contributing to effortless low-frequency reproduction.
• High-Power Reference Grade Class-D Amplification: The Depth 212 pumps out a dynamic peak power of 2,200W (1,100W RMS), while the Depth 215 doubles that with dual amplifiers achieving 4,400W dynamic peak (2,200W RMS). This ensures your bass stays precise and powerful, even at heart-racing volume levels.
• 64-bit Vojtko DSP Engine: Operating at 500MHz, this advanced DSP actively monitors and fine-tunes the subwoofer’s performance in real time, ensuring accuracy and natural musicality.
• Convection-Cooled Concealed Amplifier: The amplifier is neatly tucked away behind a rear trim with dual aluminum heatsinks, keeping things cool without noisy fans. Plus, cable management stays discreet and tidy.
• Concealed Touch Control Interface (TCI): Who needs an app when you have six backlit touch points and a clear LED display right on the subwoofer? Customize everything from volume to presets with stealthy backlighting.
• Integrated Anti-Vibration Feet: These babies minimize energy transfer to your floor and room, resulting in cleaner, tighter bass that doesn’t blur your soundstage.
• Anthem Room Correction (ARC®): The Depth Series supports MartinLogan’s award-winning ARC® tech, which calibrates your subwoofer precisely to your room’s acoustics. It includes a premium mic kit for easy setup.
• Comprehensive Connectivity: Balanced XLR and RCA inputs, speaker-level inputs, RCA Sub Out, plus lossless wireless subwoofer support cover all your hookup needs.

Where Design Meets Performance

One of the most impressive aspects of the Depth Series is how it brings together engineering prowess and elegant aesthetics. The cabinets sport a sculpted, minimalist design that whispers luxury without shouting for attention.

Every detail from the sleek, glossy black finish to the hidden amplifier compartment shows a dedication to marrying form with function. Whether sitting in a minimalist two-channel setup or a fully immersive cinema room, the Depth subwoofers blend right in while delivering earth-shaking lows with pristine clarity.
