FINE TUNING
Once you have your speakers positioned in the room and have set speaker distances
and speaker level calibration with your Processor or A/V Receiver, it’s time for a
little fine tuning.
When fine tuning your subwoofer to best integrate with the rest of your system, use
music and video soundtracks that you know well. They should contain selections
with extended bass that is continuous and repetitive.
Assess subwoofer bass output for best blend with your main speakers. It should not
be overbearing or draw attention to itself, nor should it be thin and difficult to hear.
It should add ‘weight’ and ‘punch’ to the overall sound and keep pace with your
main speakers.
If you are using a receiver, preamplifier or preamp/processor with tone controls,
set them to flat (i.e. ‘0’) and switch loudness controls off.
Some subwoofer locations may result in bass frequency cancellations. If bass sounds
dislocated or weak, adjust the phase according to the Phase Alignment Control
instructions that follow below.
SETTING SUBWOOFER CONTROLS
1. Turn the Level control completely counter clockwise to its minimum.
2. Turn the Cut-Off control to its highest frequency (i.e.150 Hz).
3. Turn the Phase control to 0° (completely counter clockwise).
4. Listen to a bass music or video selection while seated in your primary listening
area and have an assistant turn up the Level control until the subwoofer can be
clearly heard.
5. Have an assistant slowly rotate the Phase control until you hear the most bass.
Your subwoofer and front speakers are now in phase. Do not change phase
alignment again unless you move the subwoofer or front speakers to a different
location in your room, or move or remove any large items of furniture or room
furnishings (i.e. carpet, draperies, etc.)
6. Turn the Level control completely counter clockwise to its minimum.
7. Turn the Cut-Off control to its lowest frequency (i.e. 50 Hz).
8. Slowly rotate the Level control until you match the subwoofer’s volume with the
volume of your front speakers. Bass should be clearly audible, but not intrusive.
9. Slowly rotate the Cut-Off control until you hear the best subwoofer/front 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 bass balance.
