Installation: New Construction
(unfinished walls)
1. Begin by installing the iWB mounting bracket between adjacent studs.
NHT in-wall loudspeakers should only be used in the vertical orientation
(fig.5). Attach the mounting wings to the bracket by inserting them into the
locking plastic tabs in the side of the bracket (fig.2).
2. Select the desired location for the speaker, using a level to ensure that it
is precisely positioned. The wings feature progressively elongated sections
(1”, 1”, 2”, 2”, 2”, 3”, 3”) with screw holes spaced in one-inch increments.
Attach the wings to the studs with the 5 x 50mm flathead screws or staples.
For maximum stability, use two screws for each wing. Bend back the extra
portion of the wing at one of the “break” lines (fig.3).
3. Complete the pre-wiring before the drywall goes up (see “Tech Tips: Pre-
Wiring for New Construction”). Leave an extra few feet of speaker wire, and
secure it close to the mounting bracket
4. During the drywall phase, cut a hole 10 1/4” high by 8 1/8” wide around
the bracket. When installled, the frame will extend out about 1 inch beyond
the perimeter of the cutout to hide minor imperfections in the cutout.
5. If the NHT in-wall loudspeaker assembly and grille are to be painted to
match the room color, paint them now before installing the baffle (see
“Painting”).
6. After the drywall is complete, install the frame. The frame attaches to the
bracket via six plastic mounting clamps on the back of the frame that swivel
to “sandwich” the drywall between the speaker assembly and the clamps
(fig.4). First rotate the mounting clamps inward so that the body of the frame
can slide through the mounting bracket. Tighten the screws snugly, making
sure not to over tighten, as this may compromise the fit of the frame. The
gasket on the drywall side of the speaker assembly lip reduces unwanted
vibrations against the drywall and will compress slightly to allow the frames
lip to rest flush against the ceiling. The spring loaded mounting clamps pro-
vide tension once installed.
7. Connect the speaker wire to the spring posts on the back of the baffle,
making sure to observe correct polarity (see “Connections”).
8. Put the baffle into the frame so the holes on the baffle line up with the
holes in the center of the raised bosses on the frame (fig. 5). Push each 4 x
16mm screw through the holes on the baffle and into the hole on the frame
and tighten it by hand temporarily so that the baffle and the frame stay togeth-
er. Once all the screws are started, tighten each of them snugly, making sure
not to overtighten, as this may compromise the fit of the baffle. The use of
power screwdrivers is not recommended. Exercise caution to not damage the
drivers when inserting the screws.
9. Remove the protective cover from the tweeter/midrange bridge.
10. Attach the metal grille by inserting it into the grooves in the baffle.
