B&C 8CXN51 – 8″ Neodymium Coaxial Transducer for Professional Audio

The B&C 8CXN51 is an 8-inch neodymium coaxial transducer engineered for professional audio systems that require compact size, reduced weight, and uncompromising sound quality. By combining a low-frequency cone driver with a high-frequency compression driver mounted on the same axis, it delivers true point-source output. This ensures excellent phase coherence, uniform coverage, and consistent tonal balance, even in demanding acoustic environments. Designed with portability and efficiency in mind, the 8CXN51 is an ideal choice for stage monitors, compact PA enclosures, and high-performance installed sound systems.

Design and Construction

At the core of the 8CXN51 is a neodymium magnet motor system that significantly reduces weight while maintaining high power handling and efficiency. This makes the transducer especially suitable for portable systems and applications where cabinet weight is a concern.

The low-frequency section is built around an 8-inch cone driver with a 2-inch (51 mm) voice coil, engineered for stability and low distortion under continuous use. The high-frequency section features a 1-inch exit compression driver with a 1.7-inch (44 mm) voice coil and a titanium diaphragm, chosen for its durability and ability to reproduce crisp, detailed treble.

Both LF and HF elements are integrated into a single coaxial design, radiating from the same acoustic center. This approach avoids phase issues common in separate driver configurations, resulting in a smooth, coherent sound across the frequency spectrum.

Performance

The 8CXN51 delivers a balanced performance that emphasizes efficiency, clarity, and reliability. The LF driver offers strong low-end support and a clean midrange, while the HF compression driver ensures articulate vocal presence and detailed high frequencies.

Thanks to its high sensitivity, the transducer makes excellent use of amplifier power, allowing system designers to achieve higher output without oversized amplification. The HF section delivers extended treble performance with a smooth response, while the LF section provides depth and punch suitable for full-range applications.

The coaxial configuration ensures that the sound maintains uniformity on and off axis, making the 8CXN51 particularly effective in applications where consistent audience coverage is critical.

Applications

The B&C 8CXN51 is designed to be a versatile workhorse across multiple professional audio settings. Its lightweight neodymium motor makes it particularly appealing for portable PA systems and stage monitors where easy transport and high performance are equally important.

In fixed installations such as theaters, conference centers, and houses of worship, the driver’s point-source behavior ensures intelligibility and even distribution of sound across the listening area. For cabinet manufacturers and custom builders, the 8CXN51 provides a reliable and efficient solution that simplifies design without compromising performance.
