On completion of the course, students are able to:
- measure speaker parameters
- describe the properties of the basic types of loudspeaker cabinets
- select the appropriate type of cabinet for given purpose and selected loudspeaker
- design the basic types of cabinet for the selected speaker
- design a crossover for a two-band and three-band loudspeaker system
- construct loudspeaker cabinet and crossover for the loudspeaker system
- measure parameters of loudspeaker system

The knowledge of basic laws and quantities in electrical circuits is required as well as the knowledge of the characteristics of electric circuit elements, circuit behaviour with inertia elements, circuit topologies with operational amplifiers and their characteristics, periodical and non-periodical signal spectra, continuous- and discrete-time systems. The student who enrols on the course should be able to use instruments for the measurement of electrical voltage, current, and resonant frequency, waveform generators and oscilloscopes.

Not applicable.

Teaching methods depend on the type of course unit as specified in article 7 of the BUT Rules for Studies and Examinations.
- Lectures provide the explanation of basic principles, subject methodology, examples of problems and their solutions.
- Laboratory exercises support practical mastering of themes presented in lectures. Active participation of students is required.
Participation at lectures is recommended. Participation at other ways of instruction is checked.

Evaluation of study results follows the Rules for Studies and Examinations of BUT and the Dean's Regulation complementing the Rules for Studies and Examinations of BUT. Up to 24 points are awarded for elaboration of all laboratory exercises and 16 points for submitting of project - design of loudspeaker system with given drivers. Up to 60 points are given for the final examination and it is necessary to get at least 20 points for its successful completion.

1. Sound waves, audio reproduction requirements
2. Design of direct-radiator loudspeakers
3. Loudspeaker parameters and their measurements
4. Horn-loaded loudspeakers, coaxial speakers
5. Horns for horn-loaded loudspeakers
6. Semi-closed and enclosed loudspeaker cabinet
7. Bass-reflex cabinet, cabinet with passive radiators
8. Bandpass loudspeaker cabinet, push-pull system cabinet
9. Crossovers - used Filters and their features
10. Design of active and passive crossovers, their advantages and disadvantages
11. Near and far field of the loudspeaker system, effect of signal delay and diffraction
12. Measurement of loudspeaker system parameters
13. Mechanical design of loudspeaker cabinets

Not applicable.

The aim of the course is to acquaint students with the construction and characteristics of the used types of loudspeaker systems and with the methods of their design and measurement of their parameters.

It is obligatory to work through all laboratory exercises in regular or alternative terms to complete the course. Other forms of checked instruction are specified by a regulation issued by the guarantor of the course and updated for every academic year.
