The advantage of this division of labour is that each of the devices is specially designed for the reproduction of its signal component and can therefore reproduce this component perfectly in sound. Another advantage: satellites can now be built very small and thus be installed more effectively in the room. In a multi-channel sound system, at least five of the satellites must be placed at different locations in the room. So that the living room does not become some kind of speaker shrine, the possibility of being able to reduce the size of the devices is very useful.
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 systems and PC speakers> are crossover frequencies between 80 Hz and 120 Hz. In our blog you can learn about subwoofers, mid-range drivers and tweeters. Satellite speakers can be positioned differently in home cinema setups, as a centre, as rear loudspeaker or as Dipol.
