First, click to enter the settings page. There is an option for volume and tone. It's best to adjust it to the middle, then turn the knob below to make adjustments and select the settings. Next, there is a sound effect setting for the subwoofer's 3D effect. Choose the one that suits you best and rotate the knob below to adjust.
