The chamber portion includes a generally transverse face section with a housing section extending from adjacent the periperhy of the face section along a centerline of the chamber portion. The housing section includes wall elements converging from the face section. The face section and the housing section form a speaker chamber. The sound generating portion includes a low frequency range speaker mounted adjacent the face section and facing outwardly therefrom. Middle frequency range and high frequency range speakers are mounted adjacent the housing section intermediate the length thereof with the mid-range and high range speakers facing in a direction different from the low range speaker. The sound distributing portion includes a deflecting member disposed directly outside the low range speaker and closely adjacent thereto.
