    Overview Your Sunfire Subwoofer is designed to give you the best possible low-frequency sound quality for your home theater experience. It incorporates a tremen- dously powerful built-in amplifier and a pair of drivers to produce tight, floor- rumbling bass down to 22 Hz, that you can feel as well as hear.

    Control Panel Features 1. Bass Level This control lets you match the output level of the subwoofer to the level of your satellite/main speakers.

    Using the line level high-pass outputs If you are using a preamplifier which does not have a sub/LFE output, you can send its left and right front output into the subwoofer’s Line Level inputs and then connect the subwoofer’s High-Pass outputs to the inputs of your amplifier.
