Abstract
The invention is a loudspeaker for use in home theater or multi-channel sound systems that includes an enclosure, a wideband transducer, a sound absorbing pad and an aiming knob. The wideband transducer is rotatably mounted in the enclosure so that the wideband transducer can be rotated around its vertical axis and an aiming knob mechanically coupled to the wideband transducer. The wideband transducer has a front side and a rear side open so that said wideband transducer operates as a dipole transducer. The aiming knob controls the rotation angle of the dipole transducer. The loudspeaker uses the dipole transducer to create either a diffuse field or direct radiating surround sound.
