There are no adjustable tone controls on the Bose system. However, there are some ways to adjust the sound if there is too much bass:
How can I adjust the bass and treble?
Placing the system near a wall or corner can increase bass. To decrease bass, move the system farther from a wall or corner
Set the BASS setting in the system menu to NORMAL or REDUCED:
- On the remote, press and hold ALARM SETUP until “SETUP MENU” appears on the system display
- Use the TUNE/MP3 buttons to find the “BASS” setting in the setup menu
- Use the TIME +/- buttons to select the desired bass setting
- Press ALARM SETUP to exit the menu
NOTE: If the BASS option does not appear in the setup menu, a software update will be required
