many different types of speaker systems that may or may not be able to reproduce frequencies
below 80 Hz. The Bass Management setup menu lets you configure all of your speakers to
accept low frequencies below 80 Hz, or to filter out these frequencies and route them to your
front speakers, or send them only to your subwoofer channels. THX certified speaker systems
