Connecting the Subwoofer to Stereo or Dolby
®
Pro Logic
®
Systems
For stereo or Dolby Pro Logic systems, the easiest method is to use the same speaker wire connections as shown on page 5.
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 (for Boston Acoustics front speakers, refer to the included “Optimal Crossover Settings...”sheet). 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.

switch. This switch
must be turned
on
before
setting the
power mode
switch (see next page).
Adjusts the frequency of
the low-pass filter for
the subwoofer. This
control is inactive when
using the
“bypass crossover
control”
input jack.
Selects regular (0°) or inverted
(180°) polarity for the
subwoofer. Set this switch to
provide the fullest, most
dynamic bass. The effect of
phase will be most audible on
low-frequency percussion
instruments or music with a
continuously repeating bass line.
