Thank you for your purchase of the N H T
SW 10 llor SW 12 pow ered subw oofer.
Like all N H T loudspeakers, the SW 10 ll and SW 12's
developm ent has been guided by the study of hum an
hearing,it’s design rigorously tested,and its com ponents
optim ized to deliver clean,clear m usicalsound.
Since the quality of your speakers is one of the m ost
im portantfactors in m axim izing the sound you'llgetfrom
your m usic and hom e theater system , w e're sure that
you'll find your purchase of the SW 10 ll and SW 12 a
good investm ent,and invite your com m ents.
If you find your experience w ith the SW 10 lland SW 12
as satisfying as w e believe you w ill,and w ish to enjoy its
high quality sound through yourentire system ,you'llfind
inform ation about other sonically m atched N H T Super
Series loudspeakers on the back ofthis m anual.
B ackground
The N H T SW 10 lland SW 12 Pow ered Subw oofer is a
com pact, versatile and pow erful am plified subw oofer
designed to provide low frequency reinforcem entforhigh
perform ance audio and hom e theater system s.
The SW 10 lland SW 12 features:
• line-leveland speaker-levelinputs,for connection w ith
alltypes ofreceivers or other audio com ponents
• independentgain,phase and low pass filter controls
•boundary controlforadjusting system sound forvarious
room placem ent
Please take a few m inutes to read through this ow ner's
m anualbefore setting up yourspeakers;this inform ation
w illhelp you getthe m ostoutofthem . Also,please keep
the SW 10 ll or Sw 12’s packaging to use in case you
m ove or transportthem .
If you have questions at any tim e during setup or use,
feel free to call your N H T dealer or our Toll-Free
C ustom er H otline at1-800-N H T-9993.
Placem ent
N ote: To prevent the SW 10 ll and SW 12 subw oofer
am plifier from overheating, alw ays be sure to provide
adequate space for proper ventilation. D o not place the
subw oofer directly againstthe w allorany othersurface.
The key to placing yoursubw ooferforoptim alenjoym ent
is to rem em berthatlow 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 oofernearto a room boundary w illtend
to increase its apparent bass output, but m ay result in
"boom y"or"m uddy"sound. C onversely,placing itfarther
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 allchanges in subw ooferposition can have
a significant effect on sound, experim enting w ith the
effects ofdifferentplacem ents in yourow n listening/view ing room is the key to finding the sound you like best.
SW 10 lland SW 12 Features & C ontrols
Volum e: This controlallow s you to adjustthe gain ofthe
Subw oofer relative to the restofyour system . M any listeners m ake the m istake ofsetting subw oofers too loud,
w hich can cause excess bloat and loss of detail and
m usicality.A properly calibrated subw ooferblends in w ith
the speakers and does not call attention to itself. To
properly setvolum e:
• Turn dow n the volum e controlon the SW 10 llor SW 12
to its low estposition (counter-clockw ise).
• Turn on your audio system , including the SW 10 ll or
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 listening level.
•Slow ly increase the volum e ofthe SW 10 llorSW 12,listening for proper frequency balance. W hen balanced,
you w illhearim proved bass extension,butnotbe aw are
thatitis com ing from the subw oofer.
From this point on, the volum e control on your
receiver/pream plifier w ill control the overall volum e of
your system ,including the subw oofer.
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 outin the room
results in a relative decrease in bass output. Boundary
reinforcem ent m ay lead to low frequency response that
is uneven. Som e frequencies w ill sound exaggerated
relative to others, or the subw oofer w illsound thin and
lack im pact. The Boundary EQ control allow s you to
com pensate for the effects of room boundaries on the
frequency response
of the subw oofer. Adjusting the controlenables you to
achieve sm ooth low frequency output from the subw oofer regardless ofits location in your room .
The follow ing diagram s show n in Fig.1 show the correlation betw een subw oofer placem entand Boundary EQ .
These diagram s are guidelines only. Your room
acoustics and personaltastes w illultim ately dictate the
finalsetting.

Tw o tips on using the Low Pass Filter:
As a starting point, set Low Pass Filter to the 1 o’clock
position.This w illresultin an 80H z low pass.As the setting is typicalfor m ost D olby D igital/ D TS applications.
N ote:The LFE inputbypasses the adjustable 12dB Low
Pass Filter.
See the Fine-Tuning section for further adjustm ent
guidelines.
SU B W O O FER PH A SE: This sw itch sets the phase of
the subw ooferateitherthe 0° position (norm alphase)or
the 180° position (reverse phase) to achieve the
sm oothestpossible bass response in your system .
This phase-reversing option is im portantbecause ifbass
frequencies com e from both the subw ooferand the m ain
speakers,peaks and dips in the frequency response can
occuratthe listening position. In these cases,reversing
the subw ooferphase can im prove blending and balance.

LO W PA SS FILTER :This controldeterm ines the upperlim it frequency the subw oofer w ill reproduce. For
exam ple, setting the filter at 100H z w ill cause the
subw oofer to reproduce only frequencies below 100H z.
The Low Pass Filter is continuously variable betw een
40H z (low bass) and 180H z (upper bass), to
accom m odate differentspeakers.
• The correctsetting is the one in w hich the bass is the
loudestatthe listening position.
PO W ER M O D E: This feature autom atically sw itches
your SW 10 ll or SW 12 into m inim um -pow er m ode (ie,
sleep) w henever no signal is present for 20 m inutes.
W hen a signalis received,itim m ediately turns on again.
As AU TO M ode is autom atic, it requires no adjustm ent,
nor is there a need to turn the SW 10 llor SW 12 on and
off every tim e it is used. W hen in O N M ode, the subw oofer is alw ays on.

W e recom m end thatthe SW 10 llor SW 12 pow er be left
on,w hich w illallow the built-in Auto M ode feature to disable the subw oofer w hen notin use.
Every speaker,has lim its,and it's im portantto listen for
them .Speaker dam age m ostoften results notfrom brief
loud m usicalpeaks,butfrom sustained high volum e levels in som e or all frequencies. For this
reason,
extrem e volum e settings and excessive bass, treble or
equalizer boosts are notrecom m ended.
Ifyou hear unusualdistortion or breakup,or notice heat
com ing from the w oofer, decrease volum e im m ediately,
neutralize any excess bass, treble or equalizer boosts,
and avoid setting any controls to sim ilarextrem es again.
M aintenance
YourSW 10 lland SW 12 is designed foryears ofuse w ith
no orm inim alm aintenance,as long as you avoid exposing it to direct sunlight, high tem peratures, or m oisture.
C lean cabinets,w hen necessary,using a dam p cloth or
a m ild, non-abrasive cleaner; to clean grilles, rem ove
from speaker and use a soft brush or a vacuum on its
low estsetting. D o notattem ptto clean the actualdriver.
9.8 C hanging the Line Voltage Setting
The SW 10 lland SW 12 w ere designed to operate on tw o
line voltage settings,115VAC and 230VAC . In the event
that it is necessary to change the line voltage setting,
begin by turning the pow er sw itch to the off position.
R em ove allthe connections from the am plifier,including
the detachable pow er cord. U sing a flat blade screw driver, slide the sw itch to the correct position. U se the
115VAC position for 110 to 120 VAC , and the 230VAC
position for 220 to 240 VAC . N extyou w illlikely need a
pow er cord thatfits the AC receptacle and you w illneed
to replace the fuse (see "C hanging the Fuse" below )

Forsystem s operating at230 volts,use only a 5x20 m m ,
T2.0A,250-volt slow -blow fuse.
SW 12:

Troubleshooting
If the SW 10 llor SW 12 fails to operate at allw hen the

caused the protection fuse to blow.R eplace itw ith one of
correcttype and value.
Ifthe SW 10 llor SW 12 turns on butits status LED stays
red, the unit is gone into protect m ode, w hich could be
caused by incorrect w iring, short circuits, or excessive
volum e.Turn offthe Pow er Sw itch on the subw oofer for
tw o or m ore seconds to reset, and double check all
speakercables to be sure thatno sm allm etalstrands are
