(1} Completely non-directional sound
a
Four 5"(I3cm) rolled free-edge woofers and four 2"(5cm) horn tweeters are radially arranged at equal intervals around the
spherical surface. This ensures the same frequencv characteristics in all directions. The sound field is the same wherever
the listener mav be.
(2) A rich and heavy bass
The bass characteristic of the spherical waves from a breathing sphere is twice as efficient as that of the 2-dimensional waves
from an oscillating diaphragm. Since the enclosure of this speaker system is l3-1/2"(34cm) in diameter its bass reproduction
is equivalent to that of a plane baffle with two 12"(30cml woofers.
