ABSTRACT:
A loudspeaker system having an enclosure having a narrow opening or slot for radiating high frequency acoustic energy. The loudspeaker system has a cover member defining a slot between the cover member and a boundary of a listening space. The loudspeaker system may also include a fixed or adaptive equalizer for modifying frequency response anomalies resulting from the interaction of the acoustic energy, the narrow opening, and the boundary.
