The low-frequency material
reproduced by the subwoofer is
mostly omnidirectional, and this
speaker may be placed in a
convenient location in the
room. However, the best
reproduction of bass will be
heard when the subwoofer is
placed in a corner along the
same wall as the front
speakers. Experiment with
subwoofer placement by
temporarily placing the
subwoofer in the listening
position and moving around the
room until the bass
