Patented Bose® signal processing technology provides a natural tonal balance over the full range of volume settings. In most situations, placing the speakers per our recommended guidelines will provide excellent sound quality. If desired, you can further fine-tune your system as explained below.
The TREBLE and BASS controls are located on the Acoustimass® module. They allow you to adjust the treble (high frequencies) and bass (low frequencies). Each control is set from the factory in the normal, 12 o’clock, position. Turn the controls clockwise to increase, and counterclockwise to decrease, the amount of treble or bass.
The acoustics (sound qualities) of your room can affect the overall sound quality of any speaker system. In general, you can reduce many problems with acoustics by using the TREBLE and BASS controls sparingly.
Rooms with too few sound-absorbing furnishings, especially those with bare floors and walls, may sound overly shrill or “bright.” Turning down the treble control toward – decreases treble sound
Rooms with a lot of sound-absorbing furnishings, such as upholstered furniture, wall-to-wall carpet or heavy drapes, may reduce the treble sound of your system. Moving speakers farther away from soft furnishings increases treble. You can increase treble sound by slightly turning up the treble control toward +
You can decrease bass sound by turning down the bass control toward –. To increase bass, turn up the bass control toward +
Acoustimass module placement affects the amount of bass you hear. Placing the module closer to the corner of the room will increase bass. Moving the module away from the corner will decrease bass
