Atlantic Technology IWTS-8e User manual

Installation Instructions
IMPORTANT NOTE: The IWTS-8e SUB Woofer Module must be used
only with its matching Atlantic Technology amplifier (SA-380, SA-350 or
SA-700). The 8e SUB Woofer Module also must be installed and used
only within its dedicated in-wall enclosure (IN-BOX-8e SUB).
Please take a few moments to read these instructions. They're intended
not only to tell you how to mount the speakers, but how to get the
best performance from them. We always recommend a professional be
involved in the installation of Atlantic InWall Theater System speakers.
Please refer to the Installation Instructions that come with
the IWTS-8e SUB In-Wall Enclosure before installing drivers.
Important Considerations Before
Installation of IWTS-8e SUB Woofer Module
Mounting and Vibration Concerns
The 8e SUB module is designed to mount into its dedicated in-wall enclosure
which must be mounted into the wall before the sheet rock is applied. The
8e SUB Module requires 5/8 inch or thicker sheet rock to mount properly.

For use with Atlantic Technology SA-350, SA-380 Mono or
SA-700 Dual Mono Subwoofer Amplifier Only
The most critical aspect of installing the 8e SUB module is to ensure that
there are no air leaks around the unit and that the speaker wires behind the
assembly can’t vibrate against any internal part of the assembly. Take your
time when installing the foam gaskets and the module and also use great
care when attaching and locating the wires while you are mounting the
module in the enclosure.
Recommended Wire Sizes
The amplifier that accompanies 8e SUB module is very powerful. In addi-
tion it is quite likely that there will be a significant distance between the
amplifier and the woofers,necessitating long wire runs.And the longer the
wire run,the heavier the wire should be.Therefore,we strongly recommend
that you use high quality speaker wire between the subwoofer amplifier and
the 8e SUB Module. Please use at least 16 gauge for lengths up to 30 feet.
Beyond 30 feet please use larger wire; 14 gauge up to 60 feet, 12 gauge up
to 100 feet.) Remember that the wire increases in size as the gauge number
decreases. If you're in doubt, remember that it never hurts to get the next
heavier grade of wire.

Tighten the mounting screws, which will cause the bezel and the rear
clamping assembly to capture the wall board between themselves.The
bezel will conform to the wall board as it should, but BE VERY CARE-
FUL NOT TO OVERTIGHTEN THE SCREWS.
Removing and Installing the Grille
The Grille is packed separately in the box with the 8e SUB module. This
grille must fit very snugly, as the pressure and vibration created by the 8e
SUB module is quite capable of shaking the grille off the assembly. There
is a specific method of installation that must be followed in order to
properly insert the grille.
After the woofer assembly has been installed and tested for air leaks install
the grille by pressing it carefully into the side of the in-wall frame and then
slowly “rocking” it towards the opposite side making sure that the top and
bottom fit as you go along. Attempting to install the grille by putting the top
or bottom in first will generally not work. Since it’s designed to fit snugly,
please take your time and use care when installing the grille.If the grill is
very difficult to install, try backing out the mounting screws just a bit to
reduce warping of the assembly. However, be sure that the frame remains
tight against the wall board.
Remove the grille from the speaker using an awl or the point of a drywall
screw in a grille opening near one of the grille corners.Slowly pry the grille
out, being careful not to damage the speaker’s frame or its finish.
Painting the Speaker Assembly
The white plastic frame of the speaker
baffle assembly and the metal grille
may be left as is or painted to match
your decor. You can paint the frame
before or after it is installed in the
wall. Use the included paint shield to
protect against getting any paint on
the front of the speaker and only use
plastic-compatible paint.Spray paint-
ing (using paint thinned 4 to 1) is the
best method to use for painting the
grille. Multiple light coats are much
better than a single heavy coat.Be sure,no matter what method you use to
paint the grille, that you use air pressure to “blow out”any grille holes that
become covered over with paint.

InWall Enclosure/Woofer Module Installation
The woofer assembly is very heavy. Use care and caution when handling it
and mounting it in the in-wall enclosure.
1
Before mountingthe8eSUBmodule you must
first apply the 3/4 inch self-adhesive foam
sealing gasket (supplied) to the rear side of the
8e SUB white plastic frame (Fig 2). Remove
the 8e SUB assembly from its box and place it
face down on a flat surface,being careful not
to let anything damage the drivers.
2
Begin applying the foam gasket by peeling
back approximately 2 inches of the adhesive’s
protective paper cover.Starting in the middle
of one side of the back of the frame, apply
the foam gasket to the frame,being careful to
keep it at least 1/8 inch away from the outside
edge.At the corners simply continue around
the trim (do not cut the foam in any corner)
being careful not to let the foam bunch up
enough to hold the frame off the wall. Be sure that the entire frame is
gasketed with the foam.You can cut the foam on the straight sections
if necessary, but it must overlap any gaps by 1/8 inch to ensure an air
tight seal.Leave no gaps or openings as there will be serious (and clearly
audible) air leaks if you do.
3
Locate the speaker wire
that you previously ran
into the in-wall speaker
enclosure. Packed in the
8e SUB box is an 18 inch
piece of hollow core round
foam. Cut this foam to the approximate length of the wire, leaving
enough wire exposed to connect to the speaker. Run the speaker wire
through this foam and tuck it into the in-wall enclosure in such a man-
ner that it will sit within the enclosure and around the woofer magnets
when the woofers are installed in the enclosure. The foam eliminates
any possibility that the speaker wire will buzz or vibrate inside the
enclosure. (Fig. 3)
4
Strip about 1/2 inch of insulation from the connecting wires. Connect
them to the appropriate terminal on the 8e SUB being careful to observe
polarity (positive to the red terminal, negative to the black terminal).
5
Place the 8e SUB into
the enclosure, align-
ing the screw open-
ings with the screw
holes in the rear
mounting assembly
in the in-wall enclo-
sure. Be sure that
the round foam wire
insulation fits in between the magnet assemblies.If it doesn’t you may
want to trim the wire/foam to make sure it does.Use the included 3 inch
#8 self-tapping screws to attach the two assemblies together. (Fig.4)
