Course detail

Loudspeaker Systems

FEKT-BPC-REPAcad. year: 2023/2024

The course deals with description of the construction of direct-radiator and horn-loaded loudspeakers, the parameters of these loudspeakers and their measurement, the design of different types of loudspeaker cabinets and crossovers for two- and three-way loudspeaker systems, measurement of parameters of loudspeaker systems and their mechanical design. In the first part of the laboratory exercise, students measure loudspeaker parameters and design loudspeaker cabinets and crossovers and simulate their properties using LspCAD. In the second part, they construct the designed loudspeaker system, perform tuning of its crossover and measure its parameters.

Mode of study

Not applicable.

Entry knowledge

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.

Rules for evaluation and completion of the course

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.
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.


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.
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
