FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, particularly to loudspeakers. Loudspeaker has housing having front wall, side walls and rear wall. Front wall is made as a waveguide surface, in the central part of which there is a dynamic head, and is able to emit the main part of the acoustic power of the loudspeaker along the first acoustic axis. Loudspeaker has an additional dynamic head attached to the casing. Additional dynamic head is fixed inside the housing so that in its inner volume a hollow section is formed, which is limited by a dynamic head, a front wall of the housing and partitions located between the dynamic head and the front wall. Hollow section is equipped with a port that communicates with the external medium through the side wall or back wall of the body. Port is connected to a hollow section made in the form of a U-shaped cutout in the side wall, wherein the plane specified by the above cutout is substantially perpendicular to the first acoustic axis.
