Connecting Your Subwoofer to Stereo or Dolby

®

Pro Logic

®

Systems

For stereo or Dolby Pro Logic systems, the easiest method is to use speaker wire 
connections as shown.

You may also use the “sub out” connection from your receiver to the input on the subwoofer
marked 

use crossover control.

When using speaker wire or the 

use crossover control

input, the subwoofer’s built-in crossover is

engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than

the lower limit of your main speakers’ bass response. Fine-tune the crossover setting by ear for

the smoothest blend with your main speakers. The best setting of the crossover control will

depend on speaker placement and personal preference.
