PURPOSE: To give excellent low-frequency sounds throughout a room by providing a position-unestimatable woofer module which is attached to the outside of the room and communicated with an opening formed through one partition of the room. CONSTITUTION: A position-unestimatable (sound delocalized) woofer module 16 is attached to the lower surface of a floor 14 and communicated with the opening of the floor 14 below a grid 20. A left loudspeaker cube 24 and a right loudspeaker cube 26 are attached to the tracks 22 of a ceiling 12. To the module 16 and loudspeaker cubes 24 and 26, audible-frequency electric signals are supplied from an amplifier 30. A wall-mounting type volume adjusting switch 28 is also connected to the amplifier 30 and the amplifier 30 receives audible electric signals from a music center 32 containing, for example, a tuner and a cassette player. Therefore, the position-unestimatable property of the module 16 can give excellent low-frequency sounds throughout a room. |
