MartinLogan Depth 212 Subwoofer

The Depth Series is the culmination of MartinLogan’s decades long experience in designing high-performance subwoofers. Depth subwoofers are meticulously engineered to produce dynamic and powerful bass as cleanly as possible, making them an ideal choice for both dedicated two-channel systems as well as home theater applications. Depth 212’s force-canceling dual 12-inch woofer layout drastically reduces performance-robbing cabinet resonances, allowing the custom Carbon Aerocore woofers to deliver pure bass energy without coloration. The system is backed by robust, incredibly precise amplification, and controlled by a class leading 64-bit Vojtko DSP engine. Every scrupulous detail has been implemented to achieve massive output with vanishingly low distortion, while maintaining exceptional accuracy.
