The invention is a direct and omnidirectional radiating speaker with a spherical casing housing a bass element and treble element. A variable rheostat (4) is part of the speaker's dividing network and has a shaft (5) with a pendulum (6) situated in such a way that the impedance and thereby the treble level are automatically altered when the speaker casing is turned around a horizontal axle.<IMAGE> |
