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  
The front speakers should be  
placed the same distance from

listening position. They should  
be placed at about the same

listeners’ ears will be, or they  
may be angled toward the
