A8 – Diffraction is a difficult subject. I will try to give a simplified explanation of how diffraction works for an open baffle speaker after looking first at diffraction in general, and then for a closed box speaker. See FAQ 38 for actual measurements of diffraction. Fundamentally, diffraction is about the transition between an acoustic wave propagating into one space first and then into another space of different volume later. The effect, at a given point in space, is a change in sound pressure and, correspondingly, a change in the frequency response. The effect will be different whether the point is on-axis or off-axis. Take, for example, a small source on a flat baffle. At low frequencies, where the wavelength is much larger than the distance from the source to the baffle edge, the source radiates essentially unimpeded into full space (4pi). At higher frequencies and shorter wavelengths, the baffle begins to look more like a large plane because it takes increasing numbers of wavel
