Loudspeaker Box with Variable Crossover Frequency
Tomášek, Martin ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
This bachelor´s thesis deals with middle-sized loudspeaker system in D´Appolito configuration. The aim of this thesis is to design and to realize the loudspeaker system, which includes selection of suitable loudspeakers and their position in designed baffle including design of variable crossover frequency. The text is divided into a few sections, where are the points of this project described. In the first half there are briefly described basic principles of loudspeakers and design loudspeaker systems, especially 2-way loudspeakers, and specific properties of D´Appolito configuration. Then there are described principles of frequency crossovers used in loudspeaker systems and what is expected for their construction. In the second half, there is described realization of baffle itself and variable frequency crossover. Because this thesis concurs to semestral thesis, there is also a chapter about simulation. In the end there are diagrammatized the measured data of frequency and dispersion characteristics and a few dispersion characteristics for different crossing frequences.

Complete design of three-way speakers
Jalový, Michal ; Petržela, Jiří (referee) ; Slezák, Josef (advisor)
This project describes complete design of Three-way speakers. The introduction discussed the basic theoretical knowledge to the understanding of loudspeaker system design issues with regard to the physiology of hearing, the theory of acoustics, speaker characteristics, types of enclosures and the use of switches. Furthermore, based on the formula calculated parameters of a loudspeaker cabinet and speaker points to the loudspeaker of the proposed speakers.The proposal also relies on the specific measurement properties of the selected speaker impedance. Finally all data are presented for practical implementation speakers.

Three-way stereo speaker system with bassreflex
Burget, Jan ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor‘s thesis contains complete design of three-way stereophonic loudspeaker sound system with bassreflex. There is detailed description of selection of acoustic transducers, their measurements and adjustments. As an integral part of this seminar study is design of loudspeaker baffle and calculations or simulation of bassreflex. And further,this study also deals with a design of loudspeaker crossovers and their simulation. The study contains structural elements as a PCB (printed circuit board) or 3D pattern and drawings of loudspeaker box. KEYWORDS
