Different frequencies have different wavelengths. This happens differently, depending on the frequency of the sound. When this happens, the sound wave is distorted or its direction is modified. This has to do with diffraction from the edges of the cabinet, also known as edge diffraction, which we will discuss in depth.ĭiffraction happens when a sound wave meets an obstacle. A cube would be a worst choice, for example. Make sure if you divide the dimensions of the box between each other (height / width or width / length etc), you don’t get a whole number. The proportions of the box are important as well. However, other solutions like sound deadening material, will work wonders. Making a cabinet more angular, will minimize this drawback. Parallel surfaces encourage standing waves. Lets split the shape of the box into 2 categories : Of course, making sure the you got the right volume for the box is paramount, but taking care of the small details will ensure a great result. They have to make sense in terms of size and visual appeal. It is easier to integrate in your living room as a furniture. Making a rectangular box has the advantage of being easier to build, both for the mass producer and for the hobbyist. Does that mean that the best shape is a rectangle ? Not quite. They are producing rectangular shaped cabinets. But let’s dive into the subject, by observing what most of the speaker manufacturers are doing. Does speaker box shape matter ? Is baffle design important ?īaffle design and cabinet shape is important for a hi-fi loudspeaker build.
