The final paper begins with the definition and characteristics of loudspeakers. After the introductory part and introduction to speakers, speakers are divided into several types and categories. The most commonly used type are dynamic speakers and exactly one such speaker forms the base of speakers with acoustic servo feedback, and for this reason the focus of the theoretical part of the work will be on them. There are several types of dynamic speakers that can be divided according to the frequency band. Multiple speakers can be combined in boxes, thus creating a speaker system that can cover a certain range or the entire band of frequencies that the human ear can recognize. The highest quality speaker systems usually have several speaker boxes, each of which is responsible for specific frequencies. In the practical part, an example of making a speaker with acoustic servo feedback is presented. It is also stated what is needed to make such a speaker, and the programs that were used. Such a project presents unpredictable and various challenges which are also explained.
