RCF L15P540 Woofer 15" 500W 8 ohm

Description:

This high-power 15" woofer is designed for professional audio applications requiring strong output, excellent linearity, and low distortion. Suitable for use in PA systems, stage monitors, and bass enclosures, it delivers controlled and accurate low-frequency performance across a wide operating range.

Featuring a 3" inside/outside copper voice coil with a fiberglass former, the driver is engineered for efficient heat dissipation and reliable high-power operation. The combination of an exponential cone geometry and M-roll surround ensures stability and smooth movement, while the dual spider design with silicon-based damping maintains control during high excursion.

An integrated cooling system within the basket design enhances airflow and reduces thermal buildup, minimising power compression during extended use. This results in consistent performance and improved durability in demanding environments.
