Bose Corporation RC48S2-27 User Manual

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 the cautious 
use of the treble and bass adjustments in the audio settings menu.

Rooms with too few sound-absorbing furnishings, especially those with bare floors and walls, 
may sound overly shrill or “bright.” Lowering the Treble Compensation setting to a negative 
value from –1 to –15 decreases the 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 far-
ther away from soft furnishings increases treble. You can increase the treble sound by raising 
the Treble Compensation setting to a positive value from +1 to +14.

Placement of the Acoustimass module affects the amount of bass you hear. Placing the mod-
ule closer to the corner of the room will increase the bass. Moving the module away from the 
corner will decrease the bass.

You can decrease the bass sound by lowering the Bass Compensation setting to a negative 
value from –1 to –15. To increase the bass, raise the bass compensation setting to a positive 
value from +1 to +14.
