FIELD: low frequency loudspeaker, in particular, devices functioning at low frequencies.
SUBSTANCE: device contains at least one pair of loudspeakers mounted in a unified case, facing opposite sides and activated as separate elements by signals, arriving from a unified source, but having different amplitude and phase. The first loudspeaker faces forward, and the second loudspeaker faces backward to send sound signal in opposite directions, where aforementioned loudspeakers are identical or different compared to each other and are activated by amplification circuits, each one of which contains an electronic delay circuit.
EFFECT: creation of loudspeaker device with configurable directivity, with simultaneous simplification of structure and reduction of size.
