• As a general rule, bass
response increases as a
subwoofer is placed closer
to a wall. Therefore, bass
output is maximized when
the subwoofer is placed in
a corner.

Low-frequency sounds are
normally omnidirectional,

tell where they are generated
from. However, frequencies
between 75Hz – 150Hz can
be localized, especially at
higher volume levels.

the best possible performance
combined with the most flexi-
