Abstract

The present invention provides a loudspeaker which comprises:
  • a plurality of octant loudspeakers which are pivotally connected with each other;
  • each octant loudspeaker having a vertical pivotal wall provided with a bracket having a pair of projections,
  • the octant loudspeaker including a plurality of loudspeaker drivers,
  • the octant loudspeaker being an octant hollow casing made of fibrous glass reinforced plastics and having a plurality of openings on a baffle for accommodating a loudspeaker driver,
  • said loudspeaker driver including a permanent magnet and a diaphragm having a voice coil bonded thereto and an electrical terminal provided on a horizontal face of the housing; and
  • a square strut having T-shaped notches on each side face which receive the projections of the brackets for mounting the octant loudspeakers on the strut.
