In the thesis the influence of MDF and chipboard material on the acoustic properties of speaker enclosures was studied. First, the damping properties of the material with and without bitumen were measured. It was found out, that MDF has much lower damping values as particle board. Then identical inner volume speaker enclosures from both materials with panel thickness of 12 mm, 19 mm, 22 mm and 28 mm were constructed. The modal analyses of all enclosures were made and the boxes were modelled with the finite element method. The analysis showed very good correlation between the measured and modelled frequencies. The transfer functions of the boxes with the build in speakers were also measured. Based on this measurements it was found out that the enclosure, made from MDF board thickness of 19 mm corresponds well to the general requirements of the loudspeaker boxes and that for the enclosure of such dimensions there is no need for larger thicknesses panel.
