The present invention is directed to an improved high frequency acoustic speaker center cone, which may be located at a speaker coil tubular support, tube wherein the cone has a plurality of thin, pie-shaped segments radiating outwardly with each of the segments having an arcuated cross-section, so as to create a convex shape towards its center. The segments are highly concave toward the center and less concave with increasing radial distance away from the center. The width of the segments may increase linearly with radial distance so as to create a constant acoustical resistance radially. In another embodiment, the present invention is directed to a system containing both the aforesaid center cone, an outer cone with similar radial characteristics but being concave towards its center. The segments of the outer cone preferably terminate at a flexible, high sound absorption ring. The center cone fits within an orifice at the center of the outer cone. -1-
