text: audio systems use a crossover which separates out the low-frequency signal, so that it can be sent to a subwoofer, and then sends the mid- and high-range frequencies to five speakers which are placed around the listener; in a typical application, the signals sent to the surround speaker cabinets are further split up with a passive crossover into a low/mid-range woofer and a high range tweeter.
