RCF MB12N405 - 2000W 12-inch Neodymium Mid-Bass Driver with 4-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF MB12N405 is a high-performance 12-inch neodymium mid-bass driver, designed to provide excellent linearity, high efficiency, and powerful performance in demanding sound reinforcement applications. With a continuous program power handling capacity of 2000W, the MB12N405 delivers precise mid-bass reproduction while maintaining exceptional clarity even at high output levels. This driver uses advanced materials and innovative design elements to ensure both durability and outstanding performance, making it a preferred choice for high-output mid-bass and subwoofer systems.

The MB12N405 features a 4-inch fiberglass inside/outside aluminum voice coil, designed to provide high power handling while maintaining a lightweight structure for improved transient response. The driver utilizes a hypervented neodymium magnetic structure, coupled with a high flux neo disc, to offer exceptional magnetic strength and efficiency. A fibre-loaded exponential cone shape and a high excursion triple-roll surround combine to provide remarkable strength and a peak-to-peak excursion of 53 mm, allowing the driver to reproduce deep and accurate bass frequencies with minimal distortion.

In addition to its powerful voice coil and advanced magnetic design, the MB12N405 is equipped with a dual-forced air ventilation system to ensure efficient voice coil cooling, minimizing power compression during extended, high-output performance. The cone's curved design and the triple-roll surround contribute to excellent excursion control, enhancing the driver's linearity and precision across its operating range. With a frequency response range of 50 Hz to 2000 Hz and a sensitivity of 98.5 dB, the MB12N405 can deliver clear, accurate mid-bass frequencies while maintaining excellent control over low-frequency reproduction.

Whether used in subwoofer systems, mid-bass drivers, or high-output audio systems, the MB12N405 provides superior sound quality, durability, and performance. Its high sensitivity, efficient design, and impressive power handling make it an excellent choice for professional audio applications requiring both high output and clarity.
