The key to placing your subwoofer for optimal enjoyment
is to remember that low frequencies produce sounds with
long wavelengths, which interact in complex ways with
room boundaries, such a walls and corners, and other
large objects as well.
Placing the subwoofer near to a room boundary will tend
to increase its apparent bass output, but may result in
"boomy" or "muddy" sound. Conversely, placing it farther
away from room boundaries will tend to decrease its
apparent bass output, but may result in improved
articulation and clarity.
When possible, place the subwoofer in the same
horizontal plane and along the same wall as the main
speakers.
And since small changes in subwoofer position can have
a significant effect on sound, experimenting with the
effects of different placements in your own listening/view-
ing room is the key to finding the sound you like best.
SW10 Features & Controls
GAIN:
This control allows you to adjust the volume of
the Subwoofer relative to the rest of your system. Many
listeners make the mistake of setting subwoofers too
loud, which can cause excess bloat and loss of detail and
musicality. A properly calibrated subwoofer blends in with
the speakers and does not call attention to itself. To
properly set volume:
• Turn down the volume control on the SW10 to its
lowest position (counter-clockwise).
• Turn on your audio system, including the SW10. Play
some music you are familiar with and set your receiv-
er/preamplifier volume to a comfortable listening level.
• Slowly increase the volume of the SW10, listening for
proper frequency balance. When balanced, you will hear
improved bass extension, but not be aware that it is
coming from the subwoofer.
From this point on, the volume control on your
receiver/preamplifier will control the overall volume of
your system, including the subwoofer.
AUDIO/VIDEO SWITCH:
This control allows you to
optimize the SW10's performance for either music
listening or movie viewing.
When listening to music, most listeners prefer a flat bass
response that realistically reproduces the sound of live
instruments. For this setting, flip the switch to AUDIO.
