Connecting the 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.
When using the speaker wire hookup, the subwoofer’s built-in crossover is engaged. As a starting point, set the
crossover control on the subwoofer at roughly the lower limit of your front/main speakers’ bass response. Fine-
tune the crossover setting by ear for the smoothest blend with your front/main speakers. The best setting of the
crossover control will depend on speaker placement and personal preference.
For stereo or Dolby Pro Logic systems, the easiest method is to use the same speaker wire connections as shown above.
You may also use the “sub out” connection from your receiver to the input on the subwoofer marked use crossover con-
trol. When using speaker wire or the use crossover control input, the subwoofer’s built-in crossover is engaged. As a start-
ing 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.

If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect the subwoofer in
parallel with your front/main speakers (see diagram below). The subwoofer does not present any additional load
to your receiver.
Select “subwoofer-no” from your receiver’s set-up menu. This sends the subwoofer signal to the front/main left
and right speakers, and thus, to the subwoofer. Consult your receiver’s owner’s manual for more details.
