Abstract
An apparatus for re-distributing acoustic energy. The apparatus comprises a first concave surface defined as a surface of revolution of a line or curve. This curve of revolution is rotated beyond 230 degrees and thus defines a rather small opening, which has advantages in the frequency response output. Additionally or alternatively, edges of the concave surface may be rounded to provide advantageous effects in the sound output.
