Installation
IMPORTANT:
If the IN-BOX-155 is not used in New Construction situ-
ations, it's recommended that the wall cavity be treated with acoustic
filler and that all extraneous wires, etc. in the wall cavity are securely
"buttoned down" so there is no unwanted vibration or rattling after
the speaker is installed. Try to make the wall cavity as airtight as pos-
sible by sealing all the stud-to drywall seams with a flexible silicon
caulk or similar substance.
It is also recommended that you create an ‘enclosure’ by install-
ing cross studs between the existing vertical studs. Space these
cross studs approximately 30-36” apart. That will enclose the proper
amount of air volume needed for the 155 to achieve its optimal per-
formance. Again, take care to seal these cross studs to the sheetrock.

Construction
Removing and Installing the Grille
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.
To re-install the grille later, press it carefully into the appropriate opening in
the frame assembly. Since it’s designed to fit snugly, please take your time
and use care when installing the grille.
Cutting the Opening
After determining the best location for the speaker as outlined above, use
the enclosed template to cut the proper size hole.

WARNING:
Exercise extreme care before making any wall cuts to
ensure that you will not cut through any wires, pipes, or other items
that may be in the wall. You may sometimes, but not always, be able
to determine the approximate location of wires and pipes by looking
at the locations of nearby outlets and plumbing. But their location or
absence is never an assurance that there is not something within the
wall cavity.
Mounting the IWTS-155 Speakers
NOTE:
We always recommend a professional be involved in the
installation of the IWTS-155 LCR, if at all possible.
The IWTS-155 LCR can be easily mounted in most any standard wall mate-
rial, from ½ to 1½ inches thick.
Use the grille/frame assembly GFR-155,
sold separately.
The GFR's rotating wall clamps firmly fix it to the wall
surface after the proper cutout has been made. An important precautions
to take before mounting:
Keep the sides of the actual mounting hole at least ½ inch away from
beams or studs to ensure that the clamps have adequate room to rotate.
A stud or other obstruction that’s too close will stop them from properly
doing their job.
Installation of the IWTS-155 in New
Construction with Optional Back Box
For new construction, we highly rec-
ommend that you use the optional
Back Box IN-BOX-155. The Back
Box provides the correct acoustic
environment for the 155 LCR and
ensures its THX-level performance.
The rotator clamps (sometimes
called "dog legs") will easily grab
the combined thickness of 5/8"
sheetrock and the 3/8" back box's
front panel. The sheetrock must be
adhered to the front panel of the
back box very solidly and positively.
Use very liberal amounts of a high-quality construction adhesive, such as
Liquid Nails
, to ensure a secure, vibration-free bond.
Please see the installation instructions that come with the IN-BOX-155 for
more details.
Installation of the IWTS-155 in New
Construction without Optional Back Box
There may be new construction
situations where the Back Box
IN-BOX-155 is either not desired
or not feasible. For those situa-
tions, Atlantic Technology offers
an optional Rough-in Frame Kit
IN-NC-155 to ease installation in
new construction. Instructions for
its use are included with this kit.
Ask your Atlantic dealer for more
details.
