PURPOSE: To select easily the desired location of a speaker, by attaching a woofer and a sub-baffle plate selectively to either one of two attachment holes of the same shape which are formed to a baffle plate and therefore changing the attaching position of the woofer and speaker other than the woofer.
CONSTITUTION: A woofer 8 and a sub-baffle plate 10 are attached to attachment hole of the same shape which are formed to a baffle plate 7. It is possible to exchange easily the attaching position between the woofer 8 and the plate 10. Furthermore it is easy to have selection, by changing the attaching position of the plate 10 by 90°, a state in which the squawker 12 and the tweeter 13 are arranged in a direction rectangular to the lengthwise direction of a speaker box 6 (upper figure) and a state in which the squawker 12 and the tweeter 13 are arranged in a direction coincident with the lengthwise direction of the box 6 (lower figure). Then eight ways are available for the speaker location by combining above-mentioned two states. Thus it is possible to select the optimum location of the speaker in accordance with the space of a room and other factors.
