Abstract
This invention provides a speaker enclosure that is configured to minimize diffractions from occurring. The speaker enclosure includes baffle that is tapered inward both in a vertical axis and a horizontal axis to provide a smooth transition for the wave fronts to propagate from the outer edge of the speaker housing to the atmosphere. Providing a smooth transition for the wave fronts minimizes the occurrence of eddy currents so that diffractions do not interfere with the quality of sound from the driver. To stabilize or control the wave fronts in the vertical axis, the baffle may be elongated in the vertical axis to sustain the wave front in that axis.
