What is the proper setting for the crossover on my powered subwoofer?
A. If you are using Digital 5.1 home theater electronics, the best results will be obtained if you bypass the subwoofers built-in crossover altogether. Receivers with 5.1 channel processing perform their own bass management functionsthat is, they do the crossing over themselves. In this case, set the receivers set-up menu to subwooferyes and connect your subwoofer through its bypass crossover inputs. If you are not using Digital 5.1 electronics (you have an older Dolby Pro Logic receiver or a regular two-channel system, for example), or have an older subwoofer that does not have bypass crossover inputs, then the best way to adjust the variable crossover is to experiment with different settings. A good place to start is slightly above he -3dB point of your main left and right speakers. If they’re rated down to 70 Hz, for example, start around 80 Hz. Use the subwoofer’s volume control to smoothly blend its output with the rest of your system and to adjust for personal taste.
