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.
