Abstract: The invention relates to a loudspeaker housing having a front wall and a back wall and at least two similar electroacoustic transducers. Objects of the invention are to create a loudspeaker having a limited or finite housing but which makes possible a sound reproduction with a quality similar to an electroacoustic transducer which is mounted in an infinite baffle, and to improve the known loudspeakers such that particularly the first wave fronts of the radiated sound pressure waves are properly reproduced. The loudspeaker of this invention is characterized in that one of the transducers is mounted in the front walls whereas the other transducer is mounted in the back wall of the housing, that both transducers are excited in phase and that the housing is a closed housing.

Abstract: An electro-acoustic transducer has a diaphragm with a moving coil. The diaphragm consists of a flat textile carrier impregnated with a highly attenuating filling material and is highly elastic in its plane but inelastic in bending.
