RCF LF15N401 - 1800W 15-inch Neodymium Low-Frequency Driver with 4-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF LF15N401 is a high-performance 15-inch neodymium low-frequency driver designed to deliver exceptional bass performance with minimal distortion and low power compression. With a continuous program power handling of 1800W, the LF15N401 excels in high-output subwoofer applications, providing deep, powerful bass with impressive efficiency. This driver features a fiber-loaded cone assembly paired with a high-excursion triple-roll surround, enabling a peak-to-peak excursion of 52mm. This combination of materials and design provides remarkable strength and control, ensuring that the LF15N401 can handle extreme low-frequency signals with ease.

At the core of the LF15N401 is a 4-inch fiberglass inside/outside copper voice coil, which provides superior power handling while maintaining a light mass for quick transient response. The dual-forced air venting system ensures efficient voice coil ventilation, minimizing power compression and enhancing long-term performance, even during extended high-output use. The driver's dual spider design, with silicon-based damping control, offers excellent stability and control during large excursions, while the straight cone geometry further enhances the driver's efficiency and transient response.

With a frequency range from 35 Hz to 1500 Hz and a sensitivity of 97 dB, the LF15N401 delivers powerful and accurate low-end reproduction while maintaining clarity in mid-bass frequencies. The neodymium magnet structure provides a high power-to-weight ratio, ensuring exceptional performance without adding unnecessary weight. The LF15N401 is an ideal choice for high-performance subwoofer systems, where both power handling and efficiency are critical for optimal sound reproduction.
