Using Multiple Subwoofers in a Multi‐Channel System
The compact size of Ultra Subwoofers make them ideal for being used in systems that employ multiple subwoofers. This is
becoming more common in home theater environments. Action films and concerts, especially, can greatly benefit from a
substantial subwoofer setup that easily and comfortably fills the room during demanding low end sequences. The most
common multiple subwoofer setup is the use of two subwoofers, a left side and a right side, but many combinations are
possible. If you would like to use a multiple subwoofer setup, check your audio‐video processor or receiver and make sure it
has multiple subwoofer outputs.
We recommend that you initially try a left side/right side setup. Although low frequency sound waves are non‐directional in
nature, a left side/right side setup can give you a truly cohesive, powerful, smooth, and balanced soundstage.
Set the crossover, phase adjustment, and volume controls identically, then make adjustments until the subwoofers properly
integrate to your system. If you are placing the second subwoofer somewhere else in the room (other than a mirror
placement in relation to the first subwoofer), or using more than two subwoofers, experimenting with volume, crossover and
phase controls becomes crucial in achieving a balanced, well‐integrated sound for your system.
Again, practice patience! It may take a little time, but you’ll end up with an amazing sounding home theater and music
listening environment.
NOTE: When using a multiple subwoofer setup that requires different volume, crossover and phase settings between the
subs, remember to use the adjustment controls on the subwoofers themselves, instead of setting them to bypass and using
the controls on your processor or preamplifier.
