is to rem em ber that low frequencies produce sounds w ith
long w avelengths, w hich interact in com plex w ays w ith
room boundaries, such a w alls and corners, and other
large objects as w ell.
Placing the subw oofer near to a room boundary w ill tend
to increase its apparent bass output, but m ay result in
"boom y" or "m uddy" sound. C onversely, placing it farther
aw ay from room boundaries w ill tend to decrease its
apparent bass output, but m ay result in im proved
articulation and clarity.
W hen possible, place the subw oofer in the sam e
horizontal plane and along the sam e w all as the m ain
speakers.
And since sm all changes in subw oofer position can have
a significant effect on sound, experim enting w ith the
effects of different placem ents in your ow n listening/view -
ing room is the key to finding the sound you like best.

Volum e: This control allow s you to adjust the gain of the
Subw oofer relative to the rest of your system . M any lis-
teners m ake the m istake of setting subw oofers too loud,
w hich can cause excess bloat and loss of detail and
m usicality. A properly calibrated subw oofer blends in w ith
the speakers and does not call attention to itself. To
properly set volum e:
• Turn dow n the volum e control on the SW 10 ll or SW 12
to its low est position (counter-clockw ise).

SW 12. Play som e m usic you are fam iliar w ith and set
your receiver/pream plifier volum e to a com fortable lis-
tening level.

tening for proper frequency balance. W hen balanced,

The B oundary EQ : This is a feature unique to N H T
Evolution products. R eflective boundaries (such as
w alls) reinforce a speaker’
s bass output (3dB for tw o
w alls, 6dB for a corner) if the subw oofer is placed near
them . C onversely, placing a subw oofer out in the room
results in a relative decrease in bass output. Boundary
reinforcem ent m ay lead to low frequency response that
