A loudspeaker unit comprising a frame ( 1 ), an acoustic panel ( 3 ), an electric exciter ( 5 ) for exciting the acoustic panel, and a tuning element ( 7 ). The panel suspends from the frame and has two substantially parallel main sides. The exciter is disposed at a first main side ( 13 a) and comprises a stationary part and a translatable part, the translatable part being secured to the acoustic panel, the panel producing acoustic radiation upon energization of the exciter. The tuning element is disposed at a second main side ( 14 a) and extends opposite the electric exciter and is connected to the frame. In order to facilitate the manufacture of the unit, the tuning element is provided with a mounting element ( 7 a) extending through a passage in the acoustic panel, the stationary part of the electric exciter being mounted on the mounting element.
