B&C FB12NCX – Passive Crossover for 12-Inch Neodymium Coaxial Loudspeakers
The B&C FB12NCX is a professional passive crossover network specifically engineered for use with B&C’s 12-inch neodymium coaxial loudspeakers. These high-performance coaxial drivers demand precise crossover solutions to ensure accurate integration between the low-frequency (LF) and high-frequency (HF) sections. The FB12NCX is designed to provide exactly that: seamless frequency division, phase alignment, and protection, allowing coaxial loudspeakers to deliver consistent, natural sound across all environments.
Purpose-Built for Coaxial Performance
Unlike conventional two-way systems, coaxial designs place the LF and HF drivers on the same axis, creating a single-point source of sound. This configuration delivers superior imaging, improved directivity, and a compact enclosure design. However, it also requires a highly accurate crossover to prevent tonal imbalances or phase issues.
The FB12NCX is precisely tuned to address these challenges, ensuring the woofer and compression driver blend smoothly. The result is a coherent sound that maintains clarity, balance, and definition whether used for live performance, stage monitoring, or permanent installation systems.
High-Grade Component Selection
Reliability is essential in professional sound reinforcement, and the FB12NCX is built to endure. It uses air-core inductors to reduce distortion, polypropylene capacitors for long-term stability, and high-power resistors to handle demanding conditions. The network is also equipped with HF driver protection circuitry, a critical feature for safeguarding compression drivers against overloading or failure.
This level of build quality guarantees not only sonic transparency but also peace of mind, ensuring consistent operation during both live events and long-term installed use.
Smooth Frequency Response and Phase Alignment
The FB12NCX provides a carefully engineered crossover frequency tailored to the response of B&C’s 12-inch coaxial models. This ensures an optimal division of frequencies, maintaining accurate tonal balance and minimizing overlap issues that can occur in poorly designed networks.
By aligning the LF and HF sections properly, the FB12NCX preserves the benefits of coaxial design, delivering improved intelligibility for vocals, natural instrument reproduction, and a more immersive listening experience for audiences.
Simplified System Integration
One of the major advantages of the FB12NCX is its ability to simplify loudspeaker design and system integration. For cabinet builders and manufacturers, this passive network eliminates the need for complex crossover design work, offering a plug-and-play solution optimized directly by B&C.
Because it is passive, the FB12NCX also reduces system cost and complexity by removing the need for bi-amping or external DSP processing. It delivers reliable performance while keeping system setup straightforward, making it a practical choice for both portable sound systems and fixed installations.
