Design and Implementation of Active Loudspeaker System with Digital Input
Uchytil, Filip ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
The work is focused on a design of an active loudspeaker system with a bi-amp amplifier and a digital input. There is described the theory of a loudspeaker enclosure design and its practical implementation. Furthermore the work deals with a design and construction of input circuits such as a preamplifier, Baxandall tone control, active crossover, all-pass filter and S/PDIF. On the basis of the amplifier´s theory the optimal construction of amplifiers and their design are selected. The complex design of the loudspeaker box is devised so that it would reach a maximum acoustic power during the preservation of a low distortion.

Audio speaker system with baffle made from alternative materials
Hüttl, Ondřej ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This thesis firstly consists of an analysis and a description of materials suitable for construction of loudspeaker enclosures and a design of the loudspeaker system with the enclosure made of a synthetic stone. Electro – acoustics drivers have been described with a focus to a frequency range, a principle and a construction for an explanation of their function. Drivers based on electrodynamic principle have been described closely. An analysis of materials used for the loudspeaker enclosure production has been done and tradicional and alternative materials have been described as well. Specific modulus, density and stiffness have been taken as an objective evaluative criterion. An evaluation indicates appropriate properties of plastic, aluminum and stone based materials. The function and kinds of loudspeaker enclosures have been described. The function, properties and design of a vented box loudspeaker system have been described closely. The last part of this thesis is individual design of a two-way vented box loudspeaker system with the enclosure made of synthetic stone. A simulation of a driver behavior built in the enclosure and compensation circuits and crossovers design and simulation have been done. The enclosure has been designed with high stress to minimize negative effect of the enclosure to the final sound quality.

Design of PC Speakers
Smrčková, Milada ; Řezníček, Svatopluk (referee) ; Zvonek, Miroslav (advisor)
The goal of this bachelor thesis was the design of PC speakers, which it should be included innovative solving of all construction, function and too design, that it had to be keep all technical, ergonomical and economical aspects. This goal was based on a previous analysis of the issues and than it was used for processing of this bachelor thesis.

Design of Speaker
Kulich, Petr ; Sládek, Josef (referee) ; Zvonek, Miroslav (advisor)
Subject of this bachelor thesis is design of speakers. I aimed at sound system type 2.1, two satelite speakers and subwoofer. Main point of this design is simple portability and adjustability of speakers. With that corresponds used technology and ergonomic parameters. I took into account price and interier variability.

The instrumentation of the theater hall
SUFČÁK, Pavel
The goal of this bachelor thesis is to summarize technical equipment of the theater hall in Prachatice, make calculations of reverberation times of specific hall and come up with adjustments to improve acoustic characteristics of examined hall. Come up with electroacoustic improvements of installed technical devices in the hall and make a list of improvements for future.
