BEYMA FD-350: ready-made crossover for passive Beyma cabinets, 600 W AES
A two-way or multi-way cabinet needs something that divides the frequency range between its drivers. The BEYMA FD-350 does this passively, without its own power supply, sitting directly between power amplifier and drivers. It belongs to Beyma's FD series, in which the manufacturer offers pre-tuned networks for combinations from its own catalogue. The advantage over a DIY build: component values, level padding and component quality are defined by the driver manufacturer and matched to each other.
The network is rated at 600 W AES and weighs 1 kg. Both are typical figures for PA use: coils wound with heavy wire, capacitors built for high AC currents and resistors that must not overheat in continuous operation. Anyone who has built a crossover for this power class knows that weight is a sign of quality here, not a drawback.
Use and enclosure
The typical home for it is a passive PA cabinet with a Beyma woofer and a Beyma compression driver: tops, stage monitors, fixed installations without DSP amplification. The FD-350 is mounted inside the enclosure; make sure it is bolted down firmly, since 1 kg will move under transport and vibration otherwise, and keep it away from the woofer's magnet system.
What matters is that the network matches the drivers you actually use. A passive crossover is calculated for defined impedance curves; a woofer with different voice-coil inductance or a driver with different sensitivity shifts the crossover point and the level balance. So: choose the drivers first, then the matching network. If you are unsure which combination Beyma intends for the FD-350, 42.audio will help you sort it out.
What to look out for
- 600 W AES continuous rating, designed for PA systems with Beyma drivers
- 1 kg: large-section components, needs firm mounting inside the cabinet
- Use only with the intended drivers, otherwise crossover point and levels are off
- Not a substitute for a limiter: clipping stresses the high-frequency leg
Frequently asked questions
Which Beyma loudspeakers is the FD-350 designed for?
The network is tuned to specific combinations of Beyma woofer and high-frequency driver. Which ones, we will clarify at 42.audio based on your project. Dropping a crossover blindly onto unrelated drivers rarely gives a clean transition.
What does 600 W AES mean for a crossover?
AES describes continuous loading with a noise-like signal. The network handles this power without coils or resistors overheating. In practice your drivers usually reach their limit before the crossover does.
FD-350 or FD-2XA, which one suits me?
Both FD networks are rated 600 W AES and weigh 1 kg; they differ in their tuning for the respective driver combination. Take the network Beyma intends for your drivers, not the one with the nicer-sounding name.
At 42.audio you get the BEYMA FD-350 with all key data in the driver database. More drivers from this manufacturer: Atlas Beyma.
