Crossover Adjustments  
• Make sure the connections  
to the left and right “Speaker  
Inputs” have the correct  
polarity (+ and –).  
The Crossover Frequency  
Control determines the highest  
frequency at which the  
subwoofer reproduces sounds.  
If your main speakers can  
comfortably reproduce some  
low-frequency sounds, set this  
control to a lower frequency  
setting, between 50Hz – 100Hz.  
This will concentrate the  
subwoofers efforts on the  
ultradeep bass sounds  
required by todays films and  
music. If you are using smaller
