B&C FB10NCX – Precision Passive Crossover for 10-Inch Coaxial Systems
When it comes to coaxial loudspeaker design, the choice of crossover is just as important as the transducer itself. The B&C FB10NCX has been engineered to provide seamless integration between the low-frequency and high-frequency sections of 10-inch coaxial loudspeakers, ensuring accurate response, reliable protection, and natural tonal balance. As part of B&C’s dedicated passive crossover line, the FB10NCX delivers professional-grade performance while maintaining the simplicity of passive operation, making it an essential component for system designers and loudspeaker builders who want consistency and reliability without compromise.
Engineered for Coaxial Loudspeakers
The FB10NCX was specifically designed for use with B&C’s 10-inch coaxial drivers, particularly the 10NCX series. By matching the acoustic and electrical characteristics of these drivers, the crossover guarantees smooth summation of frequencies across the transition point, eliminating harshness or gaps that can occur with poorly matched networks. This optimization allows the natural tonal quality of the coaxial driver to shine through, providing excellent clarity and detail in both the midrange and high frequencies.
High-Quality Components for Reliability
Inside the FB10NCX, only carefully selected components are used. Air-core inductors and high-grade capacitors ensure low distortion, while robust resistors manage the power demands of professional audio use. This attention to detail gives the crossover exceptional stability even under heavy loads, maintaining audio integrity during demanding live sound reinforcement.
By incorporating built-in HF protection, the FB10NCX also safeguards compression drivers from unexpected overloads. This makes it a trustworthy choice in touring rigs, installed sound systems, and compact professional monitors where reliability cannot be compromised.
Seamless Frequency Integration
The FB10NCX provides a carefully engineered crossover frequency and slope that ensures seamless blending between the LF and HF sections of the coaxial driver. This design minimizes phase issues and maintains coherent wavefronts, which is critical in coaxial systems where both sources share the same acoustic axis. The result is improved clarity, precise imaging, and consistent off-axis response — qualities that make the FB10NCX suitable for applications ranging from stage monitors to portable PA systems.
Designed for Professional Applications
Whether it is installed in a small-format PA, used in stage monitoring, or integrated into custom-designed speaker cabinets, the FB10NCX brings consistency and predictability to system builders. Passive crossovers eliminate the need for bi-amping and external DSP crossover units, offering a simplified yet highly effective solution. For system integrators and designers, this reduces setup complexity while still delivering a sound that meets professional expectations.
