SF10 / SF12 POWERED SUBWOOFER Installation & Operation Manual
Introduction Congratulations on your purchase of an Destination Audio powered subwoofer! Your subwoofer is the result of many years of research and development dedicated to producing powerful, accurate bass in home audio systems. This manual contains operating procedures and specifications. We recommend you thoroughly read through the material contained in this manual before connecting your subwoofer.
SF10 and SF12 Powered Subwoofer SF10 Subwoofer SF12 Subwoofer Break In Period Allow several hours of listening time to adequately break-in the subwoofer. As the subwoofer breaks-in, the driver suspensions will loosen. The result of break-in will be an increase in low frequency response, improved definition, and increased clarity and detail. Care and Cleaning To maintain your subwoofer’s appearance, we recommend wiping it down with a clean damp soft cloth.
Features A powered subwoofer is a must-have component for any home theater or audio system. The performance of your subwoofer can greatly affect the overall performance of your system. Without a powered subwoofer, the deep bass on your music CDs and special effects on DVDs may not be heard and/or felt. Think of a subwoofer as a vital component that adds excitement to your theater or music experience.
Room Setup Suggestions In order to obtain the best possible sound from your subwoofer and speaker system, it is important to determine where the subwoofer and speakers will sound best in your listening room. Room reflections from the floor, ceiling and side walls influence the balance, imaging and overall sonic quality at the listening position. Experiment with placement to determine which location offers the best overall sound.

Subwoofer Amplifier Controls and Setup IMPORTANT NOTICE REGARDING BASS MANAGEMENT: It is important the signal being sent to the subwoofer be a non-boosted or “flat” signal. To be sure of this, check the settings on your receiver or processor to make sure any “bass boost”, “super bass” or “loudness” is set to Off. In most cases a home theater receiver or processor will determine the crossover frequency through bass management settings.
Subwoofer Amplifier Controls and Setup (continued) to auto, the amplifier automatically turns on when a signal is detected at the preamplifier or high level inputs and turns off when no signal has been detected for 15 minutes. 5. Phase Control: This control changes the phase of the subwoofer. Changing the phase will change the way the subwoofer and main speakers interact with each other at the crossover frequency.
