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

a significant effect on sound, experimenting with the
effects of different placements in your own listening/view-

SW10 ll and SW12 Features & Controls
Volume: This control allows you to adjust the gain of the
Subwoofer relative to the rest of your system. Many lis-
teners 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 ll or SW12
to its lowest position (counter-clockwise).
• Turn on your audio system, including the SW10 ll or
SW12. Play some music you are familiar with and set
your receiver/preamplifier volume to a comfortable lis-
tening level.
• Slowly increase the volume of the SW10 ll or SW12, lis-
tening 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.

The Boundary EQ: This is a feature unique to NHT
Evolution products. Reflective boundaries (such as
walls) reinforce a speaker’s bass output (3dB for two
walls, 6dB for a corner) if the subwoofer is placed near
them. Conversely, placing a subwoofer out in the room
results in a relative decrease in bass output. Boundary
reinforcement may lead to low frequency response that
