The sphere: the ideal loudspeaker casing
Sound expands spherically. Therefore, a spherical speaker casing meets all physical requirements of a loudspeaker. And when it is a spherical, high-end broadbandspeaker, the product is simply convincing.
A sphere has no parallel walls, no angles and edges, so the soundwaves don’t interfere with each other inside the sphere. Therefore, sound is reflected differently, frequency response is calmer, the sound space is wider and three-dimensional. Music is experienced as if present in the room.
A ball speaker has less self-oscillation
Of all existing casing shapes, a shere has the smallest surface area in relation to its volume. If the surface area is smaller, the oscillation is reduced because there simply is less material to vibrate in the first place. It is all about the membrane in the chassis transfering the sound impulses correctly.
Ideal stereo imaging
Spherical accoustic point sources allow sound to expand in all directions. There are no interfering angles and edges, so the sound is reflected much later. The three-dimensional, cone-shaped space in which sound expands is much wider, so listeners get more of the sound – independent from their position in the room.
Round is the most natural form for sound.
