ABSTRACT:
A loudspeaker enclosure is shaped as a truncated pyramid with all vertical edges being smoothly rounded. A high-frequency speaker is mounted in an individual spherical shell and affixed to the top of the truncated pyramid. Other speakers are mounted inside the enclosure, and the portion of enclosure adjacent the speaker in a horizontal plane is kept to a minimum to reduce standing waves. An individual sound chamber is provided for each speaker mounted inside the enclosure. The speakers are also mounted with vibration isolation mounts which vibrationally decouple the speakers from the enclosure.
