Fine tuning
Once you have the rest of your speakers positioned in the room and have set speaker distances and calibrated
speaker levels with your processor or A/V receiver, it’s time to fine tune your sub.
Subwoofer Controls
When setting the subwoofer controls use music and video soundtracks that you know well. They should contain
selections with extended bass that is continuous and repetitive. When you are adjusting your subwoofer, remember:
Bass should not be overbearing—the subwoofer should not draw attention to itself—but sound shouldn’t be ‘thin’
or difficult to hear. Certain subwoofer placement may result in bass frequency cancellations—this occurs when
your front speakers and subwoofer are ‘out-of-phase,’ in other words, they work against each other through the
crossover region. This will result in bass being reduced. If bass sounds weak or dislocated adjust the phase according
to the instructions that apply to your subwoofer in the setup procedures that follow.
Setting Subwoofer Controls
Set tone or equalizer controls on your receiver or preamplifier to flat (or 0 dB) and switch any loudness controls off.
1. Turn the Subwoofer Level control completely counter-clockwise to its minimum;
2. Turn the Subwoofer Cut-Off Frequency control clockwise to ‘Bypass’;
3. Set the Phase Switch to 0°;
4. While you listen to a selection in your primary listening area, have an assistant turn up the Subwoofer Level control
until the subwoofer can be clearly heard;
5. Have your assistant try the Phase Control Switch in both positions until you determine which one delivers the most
bass. Your subwoofer and front speakers are now ‘in phase.’ Do not change phase switch again unless you move
your subwoofer or front speakers;
6. Turn the Subwoofer Level control completely counter-clockwise to its minimum;
7. Turn the Subwoofer Cut-Off Frequency control completely counter-clockwise to 35 Hz;
8. Slowly rotate the Subwoofer Level control until you match the subwoofer output level with the level of your front
speakers. Bass should be clearly audible, but not intrusive;
9. Slowly rotate the Subwoofer Cut-Off Frequency control until you hear the best subwoofer/main speaker blend. If
the sound is too ‘thin,’ you have not set the frequency high enough; if the sound becomes ‘boomy’ you have set
the frequency too high. Adjust until you find the most natural balance.

TIP! Use a slot-head screwdriver or even a large coin to adjust
the controls on the side panel of your new subwoofer
NOTE: When using receivers with Automatic Level and Crossover setting systems such as Anthem’s ARC,
refer to your receiver’s Owners Manual for correct setup procedure, otherwise follow the instructions below.
