B&C FB12CXT – Passive Crossover for 12-Inch Coaxial Loudspeakers
The B&C FB12CXT is a professional-grade passive crossover designed specifically for 12-inch coaxial loudspeakers. Built to ensure perfect integration between the low-frequency (LF) woofer and high-frequency (HF) compression driver within coaxial designs, this crossover network delivers the balance, phase accuracy, and reliability required for both portable and installed professional sound systems. With carefully engineered crossover points, premium-grade components, and built-in driver protection, the FB12CXT provides a turnkey solution for system designers, builders, and users who demand accurate and consistent sound reproduction.
Designed for Coaxial Accuracy
Coaxial loudspeakers demand greater crossover precision than traditional two-way systems because the LF and HF transducers share the same axis. This design offers unique advantages in terms of imaging and directivity but also requires careful crossover implementation to prevent phase issues or tonal imbalance. The FB12CXT is purpose-built to meet these needs, delivering smooth integration between the woofer and compression driver while maintaining a natural, coherent frequency response across the listening area.
Whether used in compact PA speakers, high-performance stage monitors, or installed systems, the FB12CXT ensures coaxial loudspeakers perform at their full potential.
High-Quality Components for Long-Term Reliability
Like all B&C passive crossovers, the FB12CXT is built using carefully selected, professional-grade components. It incorporates air-core inductors to minimize distortion, polypropylene capacitors for stability, and high-power resistors capable of withstanding demanding usage without degradation. Importantly, the network also includes integrated HF protection circuitry, safeguarding the compression driver from overload conditions.
This attention to detail ensures the FB12CXT can withstand both the rigors of touring applications and the demands of long-term fixed installations. For end users, this means consistent sound performance and reduced risk of costly driver replacements.
Smooth Frequency Transition
The hallmark of the FB12CXT is its ability to deliver smooth, accurate crossover performance. The frequency division is carefully matched to the characteristics of compatible 12-inch coaxial transducers, providing excellent phase alignment and tonal balance. This results in improved intelligibility, natural imaging, and an overall sound that translates accurately across different venues and listening positions.
By minimizing coloration and ensuring that the LF and HF sections complement each other seamlessly, the FB12CXT enhances the inherent advantages of coaxial systems while addressing their technical challenges.
Simplified System Design
One of the major benefits of the FB12CXT is its ability to simplify loudspeaker system design. By offering a ready-made, manufacturer-optimized passive crossover solution, it eliminates the guesswork and time investment required to develop a custom network. For speaker manufacturers and cabinet builders, this translates into faster development cycles and more consistent results.
Furthermore, because it is a passive network, the FB12CXT removes the need for complex bi-amped systems and external DSP processing. This makes system integration more straightforward and cost-effective while still maintaining professional-grade performance.
