Fine Tuning the Subwoofer
The key to good subwoofer / speaker integration is
repeated listening, followed by making small re-adjust-
ments of the subwoofer controls. The most important
bass tuning functions you will control are the LOW-PASS
FILTER, followed by the VOLUME CONTROL settings
and then PHASE SELECTOR.
The frequency chart below lists some terms commonly
used to describe different bands of the frequency
spectrum. Listen to your system and make adjustments
to achieve a seamless blend between your main
speakers and the SW10 ll or SW12. Four common prob-
lems are outlined below. Follow the flow chart to correct
these. See the glossary for any terms you are unfamiliar
with.
