Enclosure Installation - NHT iWS Owner's Manual

5. During the drywall phase, the wood cover that protects the
woofer also serves as the cutout template. The template is 13 1/8"
square with 1/2" radiused corners (fig. 2). Once installed, the
bezel outer frame will extend out about 5/8" beyond the perimeter
of the cutout to hide minor imperfections in the cutout .
6. When painting the wall, leave the wood cover to protect the
woofer, and don't worry about overspray. If the bezel frame and
grille are to be painted, paint them separately before installing
them. (see the 'Painting' section in this manual)
7. Once the drywall and paint are complete, remove the wood cover and attach the bezel to the enclo-
sure via the (8) 8 X 2" panhead screws (fig. 3). Tighten screws snugly, making sure not to over-tight-
en, as this may compromise the fit of the bezel. DO NOT USE a power screwdriver for this. The foam
strips on the drywall side of the bezel frame reduce unwanted vibrations against the drywall and will compress
slightly to allow the bezel frame to rest flush against the wall.
8. Attach the metal grille by inserting it into the grooves in the bezel (fig. 4).
Enclosure Installation: Existing Construction (retrofitting finished walls)
Note: The iWS is primarily designed for new construction installations. Installing it into finished
walls requires cutting away a large piece of drywall and patching it once the subwoofer is
installed. If you are not comfortable or experienced with precision drywall work, consult a pro-
fessional contractor or custom installation professional. If the subwoofer bezel and grille are to
be painted to match the new wall, they must be painted first before being installed.
Warning: Exercise caution when drilling or cutting into exisiting walls. Do not drill through exist-
ing wires, pipes, conduits, heating or air conditioning ducts. If you feel resistance while drilling,
stop immediately.
1. Once you've selected the desired location for the subwoofer, use a studfinder or the "knock-
ing" method to locate the studs in the wall area where you wish to mount the subwoofer enclo-
sure. The enclosure is 14" wide, 3-3/8" deep and mounts neatly between 2 x 4 studs spaced 16"
apart on center.
2. Determine that there are no obstructions behind the desired cutout area. This is accomplished
by driling a hole in the cener of the cutout area and using a long "L"-shaped piece of metal (like a
coat hanger) to "feel around" behind the wall. Most walls will have a run of Romex (electrical
wiring) approximately one foot up from the floor (fig. 5). Do not attempt to cut the electrical
wires! In these cases, the enclosure will need to be mounted above the electrical wiring. If you
discover any other obstructions (such as pipes, conduits or ducts), fill the hole with patching com-
pound and try another location.
3. Once a suitable wall location has been found, carefully cut away a section of drywall 24" wide and 38" tall. Center the
24" wide hole over the two studs. There should be an opening 3 3/16" wide on either side of each stud (fig. 6). If the sec-
tion of drywall is cut out carefully, it may be re-used later to patch the wall once the enclosure is installed.
4. Locate the centerline of the studs that the iWS cabinet is to be installed between. For a 2 x 4 that is 3 5/8" deep, this
