Abstract
Acoustic loudspeaker (10) comprising a cabinet (12) extending in a direction (L), and a speaker (14) defining an acoustic axis (X). The cabinet defines a first axis (V1) perpendicular to the direction, and a second axis (V2) perpendicular to the direction and to the first axis.The acoustic loudspeaker is intended to be used in a first configuration, wherein the first axis is essentially vertical, and a second configuration, wherein the second axis is essentially vertical.The speaker is movable relative to the cabinet around an axis of rotation (D) between a first position, wherein the acoustic axis defines with the second axis a first angle less than 30°, and a second position, in which the acoustic axis defines with the first axis (V1) a second angle less than 30°. The axis of rotation makes two angles between 40° and 50° with the first axis and the second axis.
