If the subwoofer alone were responsible for the sound however, the sound would be extremely dull and imperfect, because high tones are missing here due to the construction method. Therefore, a perfect music system works together with the satellite speakers: these transducers differ from normal loudspeakers in that satellites do not reproduce the entire audible signal, but only the mid and high tones. In our blog you can read more about different speaker drivers.
For the interaction between the satellites and the subwoofer to work perfectly, a so-called crossover frequency must be defined. This value determines the frequency at which the division of labour for reproduction of low frequency or high frequency takes place. Frequency separation is usually managed in the settings menu of the 5.1 receiver. With modern receivers with automatic calibration function, the device recognizes the correct values automatically. Which crossover frequency a system needs can be read out in the technical data of the system. The most common values for home entertainment systems and PC speakers are crossover frequencies between 80 Hz and 120 Hz.
