Polk Audio Subwoofer PSW1200 - Manual (Page 13)

“Large” Advantages–
• You will probably get better blending
between main speaker and subwoofer.
• The bass “attack” or “tightness” may

HOW THE PSW1200 CAN HELP
If your system has no bass manage-
ment/speaker setup feature or if it does
not meet your needs, the PSW1200 can
help. For example, if you are torn
between setting your front main speak-
ers as “Large” or “Small”, you can use
the high pass filters on the PSW1200 to
roll off their response at 40 Hz instead
of relying on the fixed 80 Hz filter in
your receiver or processor.
Here’s another example: you have a
large full-range Center speaker like the
Polk CS1000p. You want it to play
Center bass frequencies (for better
imaging) and you also want to send
those Center bass frequencies to the
Subwoofer (to get better system
impact). But if you set your center to
“Large” and you hook up the Subwoofer
