Abstract
An audio speaker cabinet or enclosure having a sounding board and air space for enhancing the quality of sound produced by the speaker cabinet. The speaker enclosure is characterized in a preferred embodiment by a rectangular cabinet having a sounding board mounted in the cabinet enclosure interior between the front and rear panels of the enclosure, closely spaced with respect to the rear panel. A resilient membrane such as a sheet of vinyl is mounted on the front surface of the sounding board over an opening in the sounding board behind the speaker. A bass slot is included in the front panel below the speaker for air circulation into and from the enclosure interior and facilitating the attentuated sound produced by the vinyl sheet on the sounding board. In another embodiment, the vinyl sheet covers an opening provided in substantially the entire front surface of the sounding board and an air opening is provided in the rear panel for relieving pressure on the vinyl sheet as the sound from the speaker applies pressure to it. In still another embodiment the bottom edges of each of the side panels of the speaker cabinet or enclosure are bevelled or the cabinet bottom is angled rearwardly, such that the speaker cabinet leans in a rearward configuration for superior sound distribution effects.
