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. Digital Signal Processor Ultra High-Resolution 500MHz Vojtko DSP Engine with 64bit processing Frequency Response 18–120 Hz ±3 dB (Anechoic via LFE input) Low Frequency Transducer Dual Active 12" cast-aluminum basket, high excursion, Carbon Aerocore cone woofers in a BalancedForce configuration with under spider, voice coil, and pole piece venting, plus dual copper shorting rings.
