Embodiments for one-way sound absorbing systems are described herein. In one example, a sound absorbing system includes a waveguide having open ends for receiving an incoming acoustic wave and wall portions defining a first port and a second port. A first electroacoustic absorber is mounted to the first port and is electrically connected to a shunting circuit, while a second electroacoustic absorber is mounted to the second port and is electrically connected to an open circuit. The sound absorption of the system is directional dependent.

A acoustic horn includes an input port configured to acoustically couple with a front cavity of a loudspeaker, a pair of output ports leading to exterior of the horn, and a pair of channels each communicating the input port with a corresponding output port. Each of the channels has a cross section of which the area increases gradually in a direction from the input port to a corresponding output port and the areas of the cross sections of the channels in the same plane are substantially equal to each other such that the channels are acoustical symmetrical, which improves the high-frequency performance the sound waves and reduces distortion of the sound waves at low frequencies.
