Abstract: An installation assembly for a loudspeaker, in particular in a vehicle door, contains a support element having a receiving opening for the loudspeaker, a loudspeaker basket having a flange, and a sealing element in the region of a mechanical abutment interface between the loudspeaker basket and the support element. During installation, the loudspeaker extends through the receiving opening on the support side, and the flange on the basket side abuts the support element with the interposition of the sealing element. The loudspeaker basket has a number of joining elements which correspond to joining contours of the support element to produce a bayonet coupling or a push-and-turn connection.
