Audio Physic Luna - Setting Up Your Subwoofer; Fine-Tuning Volume and Crossover

English High End Series
Now start to play the music again. For this step, it is best to use a piece of music involving acousc
instruments, ideally a double bass and a male voice (bass or baritone). The song “Fever“ by Elvis Presley,
for example, is parcularly suitable for this setup process and can be found in many music collecons. The
track can also be accessed on one of a number of dierent websites if you have the opportunity to do so.
Step 2: Slowly turn the crossover frequency control knob and increase the crossover frequency
Please concentrate on the voice reproducon. Voices will most probably sound thin or cool with the
current seng at the lowest crossover frequency. Now increase the crossover frequency in small
increments unl the voices sound natural and full bodied. If you can clearly hear that the voices are
coming from the direcon of the subwoofer, this is a sign that the crossover frequency seng is too
high. When carrying out this procedure, please also pay aenon to the bass reproducon. If the bass
tones start to sound inated and sluggish at a certain point, reduce the crossover frequency somewhat
unl the sound reproducon is balanced. In this case, you may have to slightly turn the volume of the
LUNA back up.
Step 3: Finely adjusting the volume
If you can clearly hear the subwoofer, turn down the volume at this point until the sound reproduction of
the subwoofer no longer clearly stands out from that of the right and left loudspeakers.
