B² Audio Zero 12

The B² Audio Zero 12 was developed for uncompromising SPL and high-power applications and is designed for users who want to combine top performance with maximum control. The sophisticated HI-EF Class-D technology delivers enormous output power while maintaining high efficiency. Thanks to its massive power supply with four 0-GA terminals (50 mm²), high-quality half-bridge design, and comprehensive filter section, the Zero 12 is engineered for both competition vehicles and extreme daily-drive setups.

The package includes a wired remote control with clipping, voltage, and temperature indicators, allowing for precise monitoring and optimal level adjustment of the system. The variable crossover, the adjustable subsonic filter, and the continuously variable phase control allow for precise adaptation to virtually any subwoofer system.
