RCF MB15N301 - 1000W 15-inch Neodymium Mid-Bass Driver with 3-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF MB15N301 is a high-performance 15-inch neodymium mid-bass driver, designed to deliver exceptional efficiency, linearity, and power handling capabilities. With a continuous program power handling of 1000W, this driver excels in producing clean, precise mid-bass frequencies, making it perfect for professional audio systems that demand both high output and clarity. The MB15N301 features a large neodymium magnet structure, providing an extremely high flux density in the gap for exceptional efficiency and performance.

At the core of the MB15N301 is a 3.0-inch fiberglass inside/outside copper voice coil, which ensures high power handling while maintaining a light moving mass for fast transient response. The driver's advanced design incorporates a hyper-vented aluminum basket and magnetic assembly, providing excellent heat dissipation and minimizing power compression. The dual-forced air ventilation system ensures optimal voice coil cooling, allowing the driver to maintain consistent performance even during extended high-output operation.

To ensure superior excursion control, the MB15N301 uses a triple-roll polycotton surround and an exponential cone geometry. This combination allows the driver to deliver accurate and detailed mid-bass frequencies with minimal distortion. The spider design, paired with a carefully engineered cone assembly, ensures linearity and precise reproduction, even during large excursions. With a frequency range of 40 Hz to 3500 Hz and a sensitivity of 99 dB, the MB15N301 offers excellent low-end reproduction while maintaining clarity in higher frequencies.

The MB15N301 is ideal for subwoofer and mid-bass applications that require both high output and precision. Its lightweight neodymium magnet structure ensures excellent performance without unnecessary bulk, while the advanced cooling and suspension systems ensure long-term reliability and minimal distortion under high-power conditions.
