ABSTRACT:
A loudspeaker enclosure, for a loudspeaker with a diaphragm, having a front wall, a mounting and spacing device for mounting the loudspeaker spaced from the front wall such that there is significant air friction in the back wave passing through the space between loudspeaker and front wall, and an aperture defined in the front wall which is substantially smaller than the diaphragm. The enclosure can include an elliptical panel mounted to the diaphragm and spaced from the front wall. The enclosure provides for a greater bass sound and a flattened frequency response curve, as well as other improved acoustic qualities.
