Abstract: A sound projection apparatus for projecting sound into a sound receiving space such as a room or auditorium comprises a bass unit having a housing which includes at least one cavity and at least one bass drive unit enclosed within at least one cavity and an outlet port between the at least one cavity through the housing to the sound receiving space so that sounds generated by the bass drive unit in the at least one cavity can be projected into the sound receiving space. The sound projection apparatus further comprises a pod unit having a housing which forms a cavity and a plurality of drive units which are mounted within the cavity, the housing including a sound projecting face having an orifice for each of the plurality of drive units. A cone of each of the drive units is mounted outwardly in one of the orifices. A suspension support arm is attached to the bass unit and extends from the bass unit where in use the pod unit is suspended in a vertical plane with respect to the bass unit from the suspension support arm. An improvement in high fidelity sound reproduction can be provided by the sound projection apparatus by the bass unit and the suspension support arm which is attached to the bass unit so that a pod unit can be suspended above the bass unit. The suspension support arm is arranged to reduce vibrations or sound from travelling from the bass unit to the pod unit and in combination with a suspension arrangement of the pod unit from the suspension support arm reduces sound contamination from the bass unit into the pod unit. Correspondingly, sound and vibrations reproduced by the pod unit does not interfere with the bass unit.
