Like allNHT loudspeakers,the SW 10 lland SW 12's
developmenthas been guided by the study ofhuman
hearing,it’sdesignrigorouslytested,anditscomponents
optimizedto deliverclean,clearmusicalsound.
Placingthesubwooferneartoaroom boundarywilltend
to increase its apparentbass output,butmayresultin
"boomy"or"muddy"sound.Conversely,placingitfarther
away from room boundaries willtend to decrease its
apparent bass output, but may result in improved
articulationandclarity.
Since the quality ofyourspeakers is one ofthe most
importantfactorsinmaximizingthesoundyou'llgetfrom
yourmusic and home theatersystem,we're sure that
you'llfind yourpurchase ofthe SW 10 lland SW 12 a
goodinvestment,andinviteyourcomments.
W hen possible, place the subwoofer in the same
horizontalplane and along the same wallas the main
