A loudspeaker apparatus 1 includes a loudspeaker unit 3 and an installation device 2. The loudspeaker unit 3 includes drivers 22 and 23 and an enclosure for the drivers composed of front and rear members 20 and 21. The loudspeaker unit is detachably mounted to an installation device 2, which, in turn, is secured to an installation surface 11 to which the loudspeaker apparatus is to be installed. The loudspeaker unit is mounted rotatable about its center axis 25. The drivers have respective sound radiation center axes 22a and 23a, which are oriented to intersect the center line 25 at a predetermined angle theta. Thus, the direction in which the drivers radiate sound can be changed by rotating the loudspeaker unit about the center axis.
