A moveable stereo sound system (14) for use in a room (10) having a ceiling (12), the system (14) is supported by a track (30) or a cable (80, 90, 100) coupling the sound system (14) to the ceiling (12) for movement with respect to the ceiling (12). A drive motor (78, 104) is coupled to the track or cable for causing the system (14) to move with respect to the ceiling (12) either horizontally and/or vertically. Control switches (82, 98) are coupled to the drive motor (78, 104) for selectively causing the sound system (14) to move with respect to the ceiling (12) to position the sound system (14) at a desired location in the room (10). A power source is coupled to the driving motor (78, 104), to the control switch (82, 98) and to the sound system (14) to operate them. |
