About the Depth 212
The MartinLogan Depth 212 subwoofer represents the pinnacle of the Depth Series, drawing on decades of expertise in high-performance subwoofer design. It delivers dynamic, powerful, and articulate bass with exceptional clarity for both two-channel audio systems and home theater setups. The force-canceling dual 12-inch woofer layout in a BalancedForce configuration eliminates cabinet resonances, allowing the custom tri-layer Carbon Aerocore cones—composed of carbon fiber, PMI foam core, and fiberglass—to produce pure, uncolored bass energy. Powered by a reference-grade 2,200W dynamic peak (1,100W RMS) Class-D amplifier and controlled by an ultra-high-resolution 500MHz Vojtko DSP engine with 64-bit processing, it achieves massive output with vanishingly low distortion. Advanced features include Bluetooth app control for precise adjustments, integrated wireless connectivity, Anthem Room Correction (ARC Genesis) compatibility, and multiple input options. The cabinet is extensively braced with variable thickness (1-3 inches) for optimal rigidity. Finished in gloss black, it combines luxury design with uncompromising low-frequency performance.
