Spherical loudspeaker enclosures require a diameter far exceeding the drive unit size
Evidence
Firstly, in order to maintain an approximately spherical shape, a spheri cal enclosure must have a diameter that is significantly larger than the diameter of the drive unit. In Figure 6.65a the sphere’s diameter is twice that of the drive unit. If the diameter of the sphere equaled that of the drive unit the enclosure shape would be a half sphere, which would have a poorer performance than a sphere. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2204
