RCF MB15N405 - 2200W 15-inch Neodymium Mid-Bass Driver with 4-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF MB15N405 is a high-performance 15-inch neodymium mid-bass driver engineered for high efficiency and linear frequency response. With a continuous program power handling of 2200W, this driver is designed to deliver powerful, accurate mid-bass frequencies with minimal distortion, making it ideal for professional audio systems that require both clarity and high output. The MB15N405 combines cutting-edge design features, including a high flux neodymium disc magnet and a fiber-loaded exponential cone with a high excursion triple-roll, constant geometry surround, ensuring remarkable strength and control throughout its operating range.

One of the standout features of the MB15N405 is its advanced cooling system. The dual-forced air ventilation ensures efficient voice coil cooling, minimizing power compression even during extended high-output use. The driver's fiberglass former and aluminum voice coil provide exceptional power handling while keeping the moving mass light for faster transient response and a proper Q factor for bass alignment. The optimized design ensures that the MB15N405 performs with minimal distortion, even when pushed to its limits.

With a frequency range from 45 Hz to 2500 Hz and a sensitivity of 100 dB, the MB15N405 excels in producing deep, controlled mid-bass frequencies while maintaining clarity in the upper bass range. Its maximum excursion of 53 mm allows for impressive low-frequency extension, and its neodymium magnet structure ensures a high power-to-weight ratio, delivering exceptional performance without sacrificing weight. This driver is perfect for use in high-output subwoofer and mid-bass systems, where both power handling and efficiency are key factors.
