Abstract: LOUDSPEAKER SYSTEM A loudspeaker system embodies an enclosure defining a sound chamber having a front wall with a sound emitting opening therein. An outwardly and forwardly flaring speaker cone is mounted within the enclosure and adjacent the opening therein with the innermost portion of the speaker cone emitting more distorted sound than the outermost portion thereof. At least one reflector is mounted outwardly of the enclosure and forwardly of an outer portion of the speaker cone with the innermost edge of the reflector being located at least 15 per cent of the radial distance measured outwardly from the outer edge of the loudspeaker voice coil to the outer edge of the cone diaphragm with the sound being reflected by the reflector being directed outwardly of the enclosure at least 90% from a line extending forwardly along the axis of the loudspeaker cone.
