SP-CX12N251-4 Coaxial Driver for RCF NX 12-SMA

The SP-CX12N251-4 is a high-performance replacement coaxial driver designed for the RCF NX 12-SMA stage monitor system. Built for professional audio applications, this lightweight yet powerful transducer delivers exceptional clarity, high output, and reliable performance for demanding live sound environments.

Featuring a 12” coaxial design with integrated high-frequency compression driver, the CX12N251 provides accurate phase response, smooth vocal reproduction, and controlled dispersion from a single acoustic source. Its advanced neodymium magnet structure and hyper-vented aluminum basket help reduce power compression while maintaining excellent thermal efficiency during extended high-output operation.

Professional Performance

The CX12N251 is engineered to produce a coherent single spherical wavefront with consistent coverage and outstanding intelligibility. Its coaxial architecture ensures precise alignment between low and high frequencies, making it ideal for stage monitoring and critical live sound applications.

The large neodymium magnet structure provides high magnetic flux density and increased efficiency while keeping overall weight low. Advanced ventilation throughout the basket, voice coil, and magnet assembly improves cooling and minimizes thermal compression under heavy use.
