• Adjust the Variable Phase control now. This is only necessary if the subwoofer’s
position is not on the baseline between the loudspeakers or left to the left loudspeaker
and right to the right loudspeaker. If the subwoofer is before or behind the baseline, or
somewhere else in the room, adjustment of the phase might be necessary. The Phase
control is in the right position, if you’re not aware of a time difference between the
mid/high frequencies and the lower frequencies on the listening position. The system
is definitely out of phase when the bass frequencies lag behind the rest of the
spectrum or there’s a time difference anyway. If it’s not possible to get the right timing,
reverse the Phase Switch from ‘0’ to ‘180’ and try again. If this is not helpful, diminish
the distance between the subwoofer and the electrostatic panels.
•
Readjust the volume control after adjusting the phase.
• You can slightly adjust the crossover frequency. You should be unaware that there’s a
crossover ‘area’. There should be a seamless transition from the subwoofer to the
panels. Use, as an example, piano music to make the right adjustment.
• Readjust the volume control again.
•
If you have a dedicated stereo/surround setup guide/disc, refer to the directions
included in it.
• Note that you may need to try more than one location for the subwoofer to reach
optimum results.

Important information about dedicated Final subwoofers
The Final Sound subwoofers, are specially designed to match the requirements of the Final
electrostatic loudspeaker. The crossover frequencies to several models Final electrostatic panels are
programmed inside the subwoofer just as the time and phase behavior. So, contrary to common
subwoofer’s technology, the Final subwoofer is equipped with additional high pass filters for driving the
electrostatic panels. Aside of this added feature, it’s also possible to use these subwoofers in any other
non Final stereo or home theatre system.
Using these subwoofers together with the Final electrostatic panels of your choice, needs a different
approach when connecting your system.
Cross over frequency
The Final Sound Subwoofers covers the low frequency range up to 200Hz. While the F300i covers the
frequency range from 95Hz up to 20Khz, it is important to define carefully the crossover frequency
between the subwoofer and the electrostatic panels, which is influenced by the acoustic properties of
the room and the placement of the subwoofer.
The dedicated subwoofer manual, included in the subwoofer packaging, will provide
you with all the information about setting up and configuring the Final Sound
subwoofers.
How to clean and maintain the Final Sound subwoofer
After switching the Final Sound subwoofer off, always unplug the subwoofer from the amplifier and
disconnect the power cord before you start cleaning. To prevent fire or shock hazard, clean only with a
damp cloth. Never use cleansers or chemicals. Never leave a wet cloth on the surface of the cabinet.
