Installation of the IWTS-30 LCR in New
Construction without Back Box
There may be new construction situations where the Back Box IN-BOX-
30LCR is either not desired or not feasible. For those situations Atlantic
Technology offers an optional Rough-in Frame Kit IN-NC-626/30 to ease
installation in new construction. Instructions for its use are included with
this kit. Ask your Atlantic dealer for more details.
Important: If the IN-BOX-30LCR is not used in New Construction situa-
tions, 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 possible.
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.
11 1/8 x 20 3/8”
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.
Installation of the IWTS-30 LCR in Existing
Construction
NOTE: We always recommend a professional be involved in the
installation of the IWTS-30 LCR.
The IWTS-30 LCR can be eas-
ily mounted in most any stan-
dard wall material, from ½ to
1½ inches thick. Use the grille/
frame assembly GFR-626/30,
sold separately. The GFR’s
rotating wall clamps firmly fix
it to the wall surface after the
proper cutout has been made.
An important precaution to
take before mounting:
Keep the sides of the actual mounting hole at least 1½ inches 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-30 LCR in New
Construction with IN-BOX-30LCR Back Box
For new construction we
highly recommend that
you use the IN-BOX-
30LCR Back Box. The
Back Box provides the
correct acoustic envi-
ronment for the 30 LCR
speaker and it is the only
way to guarantee that
the speaker achieves
its THX-certified per-
formance. The rotator
clamps (sometimes
called “dog legs”) will
easily grab the combined
thickness of
5
⁄8” she et-
rock 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-30LCR
for more details.
