Hemispherical speaker system

摘要: An arrangement of divergently mounted acoustic transducers in a hemispherical air tight enclosure, the enclosure being sized with regard to loading requirements produce small size speaker system having an omnidirectional sound radiation pattern and flat frequency response without need crossover network. The comprised six equal sided pentagonal plates, five triangular shaped gussets base plate all which when assembled forms half dodecahedron polyhedron closed base, serving as mounting surface.
