ABSTRACT:
The loudspeaker is mounted within a hollow, essentially tubular body so that the loudspeaker structure extends into the tubular body. The tubular body is at least in part insertable into an opening of a vehicle panel, such as a dashboard, rear window shelf, or the like. The rear of the panel is closed off by a housing body, shaped to leave a space or chamber behind the tubular body; preferably, the housing body is made of a foam material, or includes, at the inside, a foam rubber material which may be of open pore structure at least in the region facing the tubular body.
