My understanding is that AF wavefronts behave the same as RF wavefronts. How big does the rounding have to be to make a difference?

I'd very much like to hear it from someone who actually understands this stuff.ĭoes edge rounding really do much difference if crossing around 1kHz using a HF driver + CD waveguide and a large DR woofer? When dealing with lower frequencies the wavelengths are so great that the rounding won't do much good anyway. Since the waveguid has such a focused directivity diffraction problems in the higher frequencies should be a non-issue. The woofer will probably match the directivity fairly well if done right. In a document found at Pi speakers you can read about the baffelwidth being a major issue and edge rounding not so much when it comes to lower frequencies.Ī waveguide might for an example exhibit a 90degree radiating pattern at the crossover frequency. Linkwitz who is a pioneer and authority in himself as well stipulates that rounding the edges will only provide benefits when the radius is greater than 1/8 of the wavelength. He recommends as large a edge radius as practical. Geddes is a pioneer and authority in the field. I'm planing on a two-way build with focus on constant directivity.

However it would be nice to have a few questions aired. I'd be lying if I claimed to actually know the truth about any of it. I've been trying to read up on diffraction problems and cabinet construction.
