Abstract: A folded-horn loudspeaker system adapted for high-power audio applications. The system preferably comprises a rigid enclosure of generally cubicle dimensions and an integral, exponentially curved horn projecting outwardly from the enclosure toward the listening area. A transducer housed within a sealed chamber interiorly of the enclosure communicates through an aperture into a waveguide system of substantially rectangular dimensions. A baffle plate system deflects sound energy from the waveguide into the throat of the horn. The baffle plate system is positioned to avoid the reflection of sound waves back into the waveguide to thereby minimize distortion.
