ABSTRACT:
To prevent the generation of audible resonation of the baffle plate by rigid connection of the weighty speaker unit, the speaker system having a cabinet including a speaker unit uses a support structure which allows movement of the speaker unit in its axial direction, and a flexible seal member fitted into a gap formed between the baffle plate of the cabinet and the frame of the speaker unit or a sub-baffle connected to the frame of the speaker unit. In one embodiment, the support structure includes a swingable plate to which the speaker unit is fixed. A clamp device is provided to prevent movement of the movable part during the transportation of the speaker system.
