USING YOUR SPEAKER SYSTEM
Balancing tone for the sound you like
The acoustics of your room affects the sound you hear there. Upholstered furniture, carpets,
and drapes absorb sound, which can muffle the treble (high frequencies). Bare floors, walls,
and furniture have the opposite effect and can make the treble sound shrill.
A bass compensation control on the Acoustimass module enables you to balance the tones
There are two ways to adjust the bass:
Turn the control clockwise to increase or counterclockwise to decrease bass.
Reposition the module. To increase bass, turn the front of the module toward a wall or other
nearby surface. To decrease bass, aim the front from the wall.

If this does not resolve the problem for the !
originally unheard speaker, this speaker may be
the cause. Contact Bose Customer Service.
If the problem switches to the other speaker (the
one that previously performed) a defective output
channel on the sound source may be the cause.
Try a different source.
