The present disclosure is directed to devices and systems for auto configuration of directional sound. The system comprises: a first and second portable bass loudspeaker, each arranged to radiate sound waves responsive to audio signals. Each portable bass loudspeaker has a sensor for determining whether the portable bass loudspeaker is in an aligned state or non-aligned state, wherein in the aligned state, the first portable bass loudspeaker is oriented in a generally parallel and opposite direction relative to the second portable bass loudspeaker. Each portable bass loudspeaker has an equalization device providing a first equalization setting for outputting audio in response to detection of the aligned state, and a second equalization setting for outputting audio in response to detection of the non-aligned state, wherein the first equalization setting is configured to generate a radiating output from the first and second portable bass loudspeaker in a cardioid pattern.
