Beyma SG-6: SG-series waveguide for Beyma compression drivers
The SG-6 is a waveguide from Beyma's SG series and weighs 0.8 kg. A waveguide differs from a classic horn in its aim: less about raising efficiency through strong loading, more about controlled dispersion that stays as even as possible across frequency. The contour is shaped so that the transition from throat to mouth runs without abrupt steps, which counteracts reflections inside the horn and the ripple in the frequency response that comes with them.
With its SG and TD ranges, Beyma offers a broad selection of horns and waveguides for its own compression drivers. With its weight, the SG-6 sits in the middle of that palette. Which throat size the waveguide accepts and which coverage angle it offers is given in the product drawing and the manufacturer's specifications, so check those before settling on a driver.
Use and enclosure
A waveguide like the SG-6 is typically meant for two-way cabinets in which a compression driver works above a mid-woofer: PA tops, installation speakers, monitors or ambitious DIY projects. The advantage over a free-radiating dome lies in the combination of higher efficiency and a dispersion pattern that matches the mid-woofer in the crossover region; ideally both sections focus similarly at the crossover frequency, so the power response in the room shows no step.
Matching drivers are found in the Beyma compression driver category at 42.audio; what matters is that the driver's horn fitting matches the waveguide's throat size and that the bolt holes line up. The crossover frequency depends on the chosen driver and the lower limit of the waveguide; a steep filter and a clear margin above the driver's resonance frequency are advisable in any horn system. For matching with the mid-woofer, the driver database at 42.audio is available.
What to look out for
- Weight 0.8 kg: design the mounting and baffle accordingly.
- Check throat size and bolt pattern against the intended Beyma driver before buying.
- The waveguide contour aims for even dispersion, not maximum loading.
- Choose a crossover with a steep filter and margin above the driver's resonance.
Frequently asked questions
What is the difference between a waveguide and a horn?
The boundary is blurred. A horn is usually designed for high efficiency and low-frequency loading, a waveguide for dispersion that is as even as possible with a smooth transition to the baffle. Both guide the sound of a compression driver, and the waveguide often behaves more neutrally.
Which Beyma drivers fit the SG-6?
All Beyma compression drivers at 42.audio whose horn fitting corresponds to the throat size of the SG-6. Check diameter and bolt pattern against the manufacturer's data before buying.
Do I need a different crossover for a waveguide than for a horn?
The principle is the same: crossover well above the lower limit, steep slope, level matching to the mid-woofer. With a waveguide the frequency response is usually smoother, which simplifies equalisation.
Beyma SG-6: manufacturer, spellings and classification
Beyma and Acustica Beyma refer to the same manufacturer: Acústica Beyma S.L. of Moncada near Valencia, Spain. The SG-6 is a horn / waveguide from the SG series, available from 42.audio, Beyma dealer in Germany, with datasheet and full specifications in the driver database.
At 42.audio you get the BEYMA SG-6 with all key data in the driver database. More drivers from this manufacturer: Atlas Beyma.
