This thesis presents the design, optimization, and construction of a pair of loudspeakers
intended for music playback. Based on the initial concept and defined design requirements,
suitable speaker drivers were selected. The process of simulating three different design
iterations is described in detail, with each iteration differing in a range of characteristics. Each iteration includes low-frequency simulation, driver placement on the speaker's front panel, and simulation of the corresponding crossover network.
A technical and cost comparison of the three iterations was conducted, followed by the
construction of the enclosure and installation of the selected drivers. After the proper break-in of the woofers, measurements were carried out, and the results were used to design and
implement the final crossover network. Further measurements and system testing followed.
The results confirmed that all design objectives were met, with the exception of a slight
deviation in the on-axis frequency response in the 100 Hz to 200 Hz range. The thesis concludes with a final cost analysis of the build and a review of the software tools used.
