„Fine Tuning the Subwoofer

The frequency chart below lists some terms commonly used to describe different bands of the frequency spectrum. The key to good subwoofer / speaker integration is repeated listening, followed by small re-adjustments 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.
