RCF MB12N405 12" Neodymium Mid-Bass Speaker Driver 2000W 4" Voice Coil

The RCF MB12N405 is a high-performance 12" mid-bass transducer engineered for superior power handling, efficiency, and linear response. Built with a 4-inch fibreglass inside/outside aluminum voice coil and a neodymium magnet structure, it delivers 2000W of continuous program power and boasts a sensitivity of 98.5 dB. Designed for professional audio systems where deep, defined mid-bass is critical, the MB12N405 features dual-forced air ventilation for minimal power compression, a triple roll surround for high excursion, and an exponential cone geometry for exceptional clarity and control across the 50 Hz – 2 kHz range.
