Beyma 2 Ways Hi-Fi: passive two-way crossover rated 300 W AES
The Beyma 2 Ways Hi-Fi is a passive two-way crossover that splits an amplifier output into a low-frequency and a high-frequency branch. The name says where Beyma places it: not on stage, but in home and studio loudspeakers where a woofer or mid-woofer and a tweeter run passively on one channel. At 300 W AES power handling it is nonetheless built far sturdier than the term hi-fi might suggest.
The weight of 2 kg stands out. In passive crossovers, mass almost always comes from the inductors and capacitors, and heavy components point to large wire gauges and low series resistance in the LF branch. That is particularly relevant in a hi-fi context, because a high series resistance in the bass inductor raises the effective Qts of the driver and shifts the enclosure tuning. Beyma is represented at 42.audio with drivers and accessories, and this crossover belongs to that range.
Use and enclosure
The 2 Ways Hi-Fi is used in classic two-way designs: a cone driver for bass and midrange, a tweeter above it, both on one amplifier channel through the crossover. Whether the concept works depends on how well the crossover frequency and attenuation of the network match the two drivers. The tweeter is almost always more sensitive than the woofer and needs to be padded down, and the crossover point has to sit safely above its resonance frequency. So check before buying which Beyma drivers this crossover is intended for, and compare their data in the driver database at 42.audio.
For installation: bolt the board firmly to the cabinet, keep the inductors away from the woofer magnet and watch the polarity at both drivers. A reversed tweeter produces a dip in the transition region that is immediately measurable and audible. The 300 W AES is the crossover's own rating, the limit of the whole system is ultimately set by the weaker driver.
What to look out for
- Two-way crossover for home and studio loudspeakers, 300 W AES power handling.
- 2 kg weight: provide a solid mounting inside the cabinet.
- Crossover frequency and attenuation must match the chosen Beyma drivers.
- Check the polarity of both branches when wiring.
- The weaker driver, not the crossover, sets the system power handling.
Frequently asked questions
Does this crossover fit any two-way loudspeaker?
No. A passive crossover is designed for specific impedances, sensitivities and a crossover frequency. It only works cleanly when the drivers used match it. Clarify the pairing before buying, 42.audio can help with selecting suitable Beyma drivers.
Why does a hi-fi crossover need 300 W AES?
Power handling in crossovers is mainly about the voltage rating of the capacitors and the saturation limit of the inductors. Headroom means the components operate far below their limits in normal use, which benefits low distortion.
Can I replace the crossover with an active solution?
Yes, a DSP with two amplifier channels takes over the split and the level matching without passive components. The passive approach has the advantage that a single amplifier is enough and the speaker runs on any integrated amp.
