RCF L15P540 - 1000W 15-inch Ceramic Low-Frequency Driver with 3-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF L15P540 is a high-performance 15-inch ceramic low-frequency driver designed to provide excellent power handling, linearity, and very low distortion. With a continuous program power handling capacity of 1000W, this driver is perfect for subwoofer applications requiring deep bass reproduction with outstanding efficiency. The L15P540 uses a 3-inch fiberglass inside/outside copper voice coil to ensure superior power handling while maintaining a lightweight design for improved transient response. This combination of design elements makes the L15P540 an ideal choice for both professional audio systems and high-output subwoofer applications.

The L15P540 features a dual spider design with silicon-based damping control, ensuring excellent stability and minimal distortion even during high-excursion operation. The dual sealed spider system, along with an efficient radiator integrated into the basket design, facilitates superior heat dissipation and minimizes power compression. This system allows for more efficient cooling, ensuring that the driver performs consistently even under demanding conditions. The M-roll surround, combined with exponential cone geometry, provides exceptional excursion control and helps reduce distortion during large movements.

The LF15P540 has a frequency range from 40 Hz to 2000 Hz and a sensitivity of 98 dB, which ensures it can deliver both deep sub-bass and clear mid-bass frequencies with minimal distortion. Its maximum excursion before damage is 36 mm, while its maximum linear excursion is 7 mm, allowing for impressive low-frequency reproduction. The ceramic magnet structure delivers a high power-to-weight ratio, providing both excellent performance and durability. The L15P540 is engineered to perform reliably in demanding environments, offering a robust and efficient solution for subwoofer and mid-bass systems.
