This bachelor’s thesis deals with the design of a stereophonic two-way loudspeaker system with a concrete enclosure. Furthermore, the preparation and casting of the concrete itself are described. The design included theoretical tuning of the enclosure, the choice of the bassreflex configuration and computer simulation. After the enclosure was completed, the drivers were installed and measured under laboratory conditions. The measured data were subsequently used for the design and simulation of the loudspeaker crossover network. The complete loudspeaker system, including the crossover, was realized as a fully functional prototype, and its parameters were measured. The thesis is concluded with the final measurement of the functional concrete loudspeaker prototype and a summary of the obtained parameters.
