How Do I Change the Bass on a 321 Bose?
Change the bass on the Bose 321 Home Entertainment System using the Bass Compensation option in the Settings menu. According to Bose, the placement of the Acoustimass module affects how much bass you hear. Place the module close to a corner to increase the bass, or keep it far from corners to reduce the overall bass in the room.
