RCF MB12G301 - 800W 12-inch Ceramic Mid-Bass Driver with 3-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF MB12G301 is a high-efficiency 12-inch ceramic mid-bass driver, designed to deliver outstanding sensitivity, excellent linearity, and low distortion. With a continuous program power handling of 800W, this driver excels in providing precise and controlled mid-bass frequencies while maintaining exceptional sound quality. Built with high-quality materials, the MB12G301 is engineered to withstand 400W RMS power, making it perfect for high-output audio applications such as live sound reinforcement and professional sound systems.

The MB12G301 features a 3-inch fiberglass inside/outside copper voice coil, providing excellent power handling and thermal efficiency. This design allows the driver to handle high power levels while keeping the moving mass light for fast transient response. The driver's advanced cooling is further enhanced by its M-roll surround and curved cone geometry, which offer excellent excursion control and minimal distortion. The combination of these design elements ensures that the driver maintains clarity and accuracy even during high-excursion operation.

With a frequency range of 50 Hz to 3000 Hz and a sensitivity of 98 dB, the MB12G301 is capable of delivering deep, powerful bass and clear mid-bass frequencies. The driver's maximum excursion before damage is 38 mm, and its maximum linear excursion is 6 mm, allowing it to handle significant signals with minimal distortion. The ceramic magnet structure ensures excellent efficiency and a high power-to-weight ratio, making the driver both efficient and durable. The MB12G301 is CE compliant, ensuring it meets safety standards for professional installations.
