Abstract
An apparatus (100), including: a speaker (152, 154); a baffle (104) surrounding the speaker; and a dispersion cone (106) positioned forward of, aligned with, and pointing toward the speaker and having a dispersion surface (120) with: a dispersion surface central section (122); a dispersion surface surrounding section (124) therearound; and a transition (126) therebetween. From a tip (122T) of the dispersion cone outward the dispersion surface central section defines a concave cross-sectional shape (170), the dispersion surface surrounding section defines a less concave cross-sectional shape (172) than the concave cross-sectional shape of the dispersion surface central section, and the transition comprises an inflection point (124IP). A distance of each section of the dispersion surface forward of the speaker progressively increases with increasing radial distance from a radial center of the dispersion surface.
