Adjust Subwoofer Controls for Listening Preferences
Now it’s time to adjust the subwoofer controls to match your listening environment and preferences.
1. Play some music through your receiver.
2. Turn the subwoofer’s VOLUME to a level that balances with the output volume of your satellite speakers
and doesn’t distort the bass sounds. You might also want to adjust your receiver’s LFE output volume
higher, if you can’t get a loud enough subwoofer output, or lower, if the subwoofer output is too loud.
3. If you didn’t use the LFE INPUT on the wireless transmitter, optionally, adjust the subwoofer’s LOW
PASS FREQUENCY to provide a wireless transmitter input equivalent to an LFE input. The LOW PASS
FREQUENCY is the frequency at which the subwoofer’s output starts to decrease as the frequency
increases. Your satellite speakers output the frequencies not covered by the subwoofer. You want to
not be able to hear the transition from the subwoofer output to your satellite speakers’ output. You can
adjust this frequency from between 50 Hz to 200 Hz. To adjust this frequency:
a. If your satellite speakers are small with limited low frequency output, choose a LOW PASS
FREQUENCY of between 100 Hz and 120 Hz.
b. If your satellite speakers are larger with better low frequency output, choose a LOW PASS FREQUENCY
of around 80 Hz.
c. Adjust the LOW PASS FREQUENCY based on listening to your audio system until it sounds pleasing to
your ear.
4. Optionally, switch the subwoofer’s PHASE to 180°. This reverses the phase of the subwoofer to correct
for sound cancellations between your subwoofer and your satellite speakers. To determine which PHASE
is best for your room and subwoofer location:
a. Listen to the system with music playing.
b. Ask a friend to switch the PHASE switch from 0° to 180° while you listen for a change in the mid-
bass loudness.
c. The correct PHASE is the one that you hear as having louder mid-bass.
d. If you can’t tell a dierence, keep the phase at 0°.
5. Go to the Adjust Subwoofer Location for Listening Preferences instructions next.
Adjust Subwoofer Location for Listening Preferences
Optionally, you can now optimize the location of the subwoofer for your listening preferences by either using the
“Crawl Test” or the “Move Test.”
Crawl Test
In this test, the subwoofer stays in one spot and you move around the room to dierent listening spots. To do
the “Crawl Test”:
1. Place the subwoofer on the oor or table near your most often used seating location. Velodyne doesn’t
recommend placing the subwoofer on the actual seating surface. The weight of the subwoofer or its
corners could damage the seating surface or structure. Also, placing the subwoofer on a very soft
surface, such as a sofa cushion, will not allow the downward ring speaker cone to extend out freely
without hitting the surface and causing damage to the speaker.
2. Play some music on the audio system.
3. Crawl around to various spots in the room until you hear the best sounding bass output to you. When
you hear the best bass output, you have determined the placement of the subwoofer for your listening
preferences.
4. Re-locate the subwoofer from the seating location to the spot you crawled to that sounded the best.
5. You’re done with this best placement test and setting up the subwoofer. Enjoy!
