B&C FB354V2 – High-Performance Passive Crossover for DCX354 Coaxial Driver
The B&C FB354V2 is an upgraded passive crossover network engineered specifically for the B&C DCX354 coaxial compression driver. Designed to deliver professional-grade performance, this crossover ensures precise integration between the low-frequency and high-frequency elements of the coaxial driver. Its enhanced components, protective features, and optimized frequency division make the FB354V2 ideal for portable PA systems, stage monitors, and permanent installation applications.
Optimized for DCX354 Coaxial Integration
The FB354V2 is tailored to maintain phase coherence and smooth frequency response in the DCX354 coaxial driver. By accurately splitting the frequency spectrum between the LF and HF sections, the crossover ensures that each driver receives the appropriate signal, reducing distortion and preserving tonal balance.
This precision is essential in coaxial systems, where phase alignment directly impacts imaging, clarity, and overall sound quality. The FB354V2 guarantees reliable, point-source performance, producing natural, full-range audio suitable for professional environments.
Enhanced Asymmetrical Slope Design
Featuring an asymmetrical slope crossover at 5.6 kHz, the FB354V2 provides 18 dB/octave on the low-pass side and 12 dB/octave on the high-pass side. This design allows for a smooth transition between the low-frequency and high-frequency drivers, minimizing phase distortion while maintaining optimal sensitivity across the crossover point.
The asymmetrical configuration ensures the midrange driver handles the appropriate bandwidth, while the compression driver focuses on high-frequency content. This creates a seamless and balanced sonic output, crucial for live sound applications and high-fidelity monitoring.
Industrial Filament Bulb Protection
To protect the high-frequency driver from overload, the FB354V2 incorporates industrial filament bulbs in series with the HF path. This built-in safeguard prevents excessive power from reaching the compression driver, enhancing reliability and extending the life of the coaxial system.
By using filament bulbs rather than traditional fuses or electronic limiters, the FB354V2 provides a smooth, gradual response to over-power conditions, maintaining tonal integrity while reducing the risk of sudden driver failure.
Designed for ME464 Horn Compatibility
The FB354V2 is optimized for use with the B&C ME464 horn, creating a complete point-source solution. When paired, the driver and horn deliver a flat frequency response, wide coverage, and precise imaging. This combination is ideal for both portable and fixed systems, ensuring consistent performance in any professional audio environment.
Its compatibility simplifies system design and installation, providing a reliable, plug-and-play solution that maintains the quality and performance B&C is known for.
High-Quality Component Construction
The FB354V2 features premium air-core inductors, high-grade polypropylene capacitors, and robust resistors. These components ensure low loss, minimal distortion, and long-term thermal stability. The passive network is engineered to maintain accurate sound reproduction under continuous high-SPL operation, making it suitable for demanding live sound or installation environments.
Every element of the FB354V2 is built to rigorous quality standards, ensuring that the crossover performs consistently and reliably over time.
