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
cr
ossover 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
cr
ossover contr
ol will depend on speaker placement and personal pr
efer
ence.

If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect the subwoofer in
p
arallel 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
andright speakers, and thus, to the subwoofer. Consult your receiver’s owner’s manual for more details.
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 to 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.
