Description
The RCF CX15N351 is a high-performance 15-inch neodymium coaxial driver, designed for exceptional linearity, high power handling, and minimal distortion. Featuring a 3.5-inch copper voice coil for the mid-bass and a 2.5-inch pure titanium diaphragm compression driver, it delivers powerful, clear, and dynamic sound. Its dual-force air ventilation and demodulation ring ensure low power compression and fast transient response. The structural polyurethane horn provides a coherent wavefront and controlled dispersion, making it ideal for high-quality professional audio applications.
