6. If the iW4 bezel frame and grille are to be painted in the wall, paint

now before installing the baffle (see "Painting" on the last page).

7. NHT offers iWF foam blocks to optimize the performance if your

iW4. See the web site for more information: nhthifi.com Refer to the

diagram (fig. 6) for orientation of the foam blocks. Insert one of the 4"

x 4" x 8" foam blocks vertically through the speaker cutout. Push this

block down below the edge of the cutout. Insert the second 4" x 4" x

8" foam block and push up above the top edge of the speaker cutout.

Bend one of the 4" x 4" x 16" foam blocks into a U shape and push

down into the wall horizontally so that it is below the speaker cutout.

Make sure that there is a good seal with the edge of the foam and

both the left and right wall studs. Repeat for the upper 4" x 4" x 16"

foam block. The foam should also make a good seal around the

speaker wires.

8. Add a 26" long piece of unbacked R19 fiberglass insulation to the

enclosure. (Be sure to wear protective gloves and goggles when han-

dling fiberglass to avoid contact with the fiber). You may need to cut

a 11" wide by 7" high rectangular hole in the center of the piece of

fiberglass to make room for the crossover on the back of the baffle.

screws that line up with the 12 holes in the bezel (fig.7). Exercise cau-

tion not to damage the drivers. Tighten screws snugly, making sure

not to over-tighten, as this may compromise the fit of the baffle. The

use of power screwdrivers is not recommended.
